Fan’s NC Miata: Truncating Ten Years

Pursuing a PHD prevents a serious student from doing much else, both for temporal and financial reasons. Fan You recognized the limitations he was under while going for another degree, but had already committed to finding a way realizing his newly-realized ambition of running track days. 

“I had no idea they existed before I moved to San Francisco in 2021,” he said. 

In his typical investigative fashion, he began researching what paths people took to getting acquainted with track driving techniques and how to best practice. For the amount of money he had available at the time, the simulator made the most sense. 

“I read and asked around, and realized the fidelity of modern simulator equipment is very good and would help me learn the techniques of driving.

After driving the simulator, I enjoyed it as a standalone and, even if I never actually raced on a track, I saw it as a good investment. My friends and I started a team, Drag-On Racing, and I dedicated nearly 1,000 hours to the simulator in the first 18 months of ownership.”

That analytical approach shaped his four-step process designed to sharpen his sword in the shortest time possible. 

All his sim preparation was put to the test on his first day of real-world track driving. This, the second step in his plan, depended on two changes: an acceptance of his limitations and disposable income.

A new job allowed him to buy his first track car: a Hyundai Veloster N, a “perfect beginner’s car” which he left untouched. “I was impressed with the suspension, the brakes, and the balance. The transmission was also quite responsive — some call it the ‘Korean PDK.’”

“Based on the research I did, I thought that starting track driving in an automatic front wheel-drive car would be safest to begin track driving; I was not sure I could deal with a RWD’s tendency towards oversteer.”

After a few DEs with his new acquisition, Fan started to probe. “I played with tire pressures and the rear sway bar to make the car a little more playful.”

That calculated sort of curiosity turned out to bolster his confidence in a way he hadn’t anticipated. “Turned out correcting oversteer is easier in real life. When you have the sensations from the car telling you before it begins to slide; you don’t have to rely completely on your vision.”

That was his first impression. As it happened, the tendency to oversteer caused by these setup changes, combined with his growing confidence, nearly cost him big. “It got away from me in Sonoma’s Turn 10, but I just barely saved it. Without my simulator preparation, I would’ve totaled the car,” he admitted. 

The third step in his process was again facilitated by a bump in income. As part of acquiring a rear-drive car with a manual transmission, a platform he felt comfortable with only after his front-drive introduction, he had to wait for a reasonable time to make a purchase. 

As all his prudence would’ve guaranteed, a big win in a poker game helped him secure the funds to pick up a cheap track toy. His deep-pocketed indifference even kept him from looking underneath the car before buying, but, fortunately, he found a mint example of a 2014 Mazda MX-5 Club package. As he would learn, the car was not stock. 

“It’s a shame more people don’t seriously track the NC. It is the redheaded stepchild in the Miata family but for me, it’s a cheap, reliable, and fun platform,” he said. 

Before he could have it inspected, he had to admit to his own shortcomings: he couldn’t drive a stick well enough to bring it home from the dealership. They transported it to him the next day. 

Over the following month, he found slow streets and cul de sacs to practice all he’d learned from his YouTube research. His shifting skills weren’t world class, but by the end of two weeks, he’d been able to coordinate his inputs well enough to make it from stoplight to stoplight. 

Then Gary Yeung at Elite Performance looked underneath and relayed tale of buried treasure. “It actually came with Ohlins DFVs and Whiteline Swaybars. “A nice bonus,” he said. “I’d watched Gary drive his Mango S2000 before and realized he was a very good driver as well as a very good mechanic, so I left all future work on my car in his and Melody’s hands after that. Elite Performance is a great shop and deserves more recognition.”

Following its post-purchase inspection, Fan ordered a Hard Dog rollbar and a set of Hawk DTC-60 pads, as well as a set of 225-section Nankang CR-S tires. During his first event in the Miata, a damp day at Laguna Seca, he remained cautious due to the way a shower the night before left a few rivers running across the track. 

The conditions and Fan’s unfamiliarity with an h-pattern gearbox were his greatest hindrances that day, but despite running the full track in fourth gear alone, he snagged an impressive 1:51.2. Relative to some of the full-out benchmark laps, Fan felt he wasn’t far off his potential performance. “That made me recognize the car’s potential,” he said. 

At Gary’s recommendation, he went ahead and prepped it for pushing harder with a small selection of modifications. With a better Hawk DTC 70/60 split, 17x10” Apex VS5-RS wheels wrapped in 255-section RE71RS tires, a Goodwin Racing radiator, and a camber kit, the MX-5 was ready for Fan’s second attempt at the famous Monterey circuit.

Favorable conditions and improved contact patch helped him snag a 1:48.2 at Laguna — with his AIM goading him on with an optimal time of a 1:47.0 — a time that put the S5 record in his sights. 

After an encouraging demonstration at Sonoma, he returned to Laguna Seca to log his current best of a 1:45.29, even with a silly mistake in T2 that robbed him of half a second. 

If he can find a cool morning free from traffic and commit more to Turns 6 and 8, he’s confident he’ll claim something in the high-44s. “It’s a matter of bravery; the car is more than capable at this stage.”

When he reaches the limits of current setup, he’ll start his fourth step: increasing power, improving aerodynamics, and reducing weight. “With these modifications, a sub 1:40 lap might be possible, but it’s too early to say conclusively.”

The rapid progression from novice to aspiring record-breaker can’t be attributed to anything other than two things: his two-thousand hours of sim driving accrued over the last few years and, of course, his need to realize his current setup’s potential. The main motivation behind my four-step plan was to train myself to be a well-rounded driver, capable of both manual and automatic, both FWD and RWD, with and without power, with and without aero. Actually, the reason for more power isn't to go faster, but to improve my throttle control.”

It was Fan’s analytical powers and prudent planning that helped him acquire the experience that would typically take ten years in just three. “From my research, I could tell that the important thing was seat time. If you want to be good at driving, you need to drive more than twenty events a year, which is already a lot for me — this is the main advantage of the simulator.”

If Fan’s been able to prove anything by truncating ten years, it’s the value of simulated seat time. Go get a rig – it’s one of the few ways you might make a return on your racing investment. 

Chris’ Evora: Penny-Pinching Pays Off

After several successful years in time trials with two different E36 M3s, Chris Mayfield decided to modernize his equipment.

After that came a short spell with a supercharged E92 M3. As fast and capable as it was with stock power, once adding the supercharger, no matter what he tried, it would not put the power down effectively. He then recognized what the limitations of a front-engined, rear-drive GT sans transaxle were — particularly when the power figure creeped too high. The more power a road racing car must handle, the more value there is in moving the center of mass closer to the driven wheels.

Frustrated with the heavy GT, Chris contemplated hanging up his helmet, but fortuitously, a friend mentioned that one of his contacts happened to be selling a European sports car for a reasonable price. This Lotus Evora’s 2GR engine would make comparable power to the S54, and the chassis would be able to put it down quite easily. It also came with plenty of go-fast bits from factory, so it wouldn’t require as much fettling as the heavier front-engine GTs had. Best of all, if it wasn’t what he wanted, he could make a few quick fixes and turn it for a profit. Considering the bargain he got on the Evora, he named it Penny and began tracking it.

Fabulous From Factory

Even in stock trim, the Evora was refined enough for thousand-mile journeys and direct enough for respectable times at more technical tracks. Though its helical LSD would lock abruptly and induce a little more rotation than intended, it was soft in its breakaway, and always communicative thanks to a fast, feelsome hydraulic steering rack.

Having a torquey motor and sixty percent of the weight over the rear axle make the Evora easy to slide in stock trim. 

Before testing the Evora, he’d expected something more along the lines of a heavier Elise, but the bigger brother was far more forgiving. Even in stock trim with excessive body roll, its soft edges helped him clock a 1:58 around Buttonwillow 13CW his first time out — an impressive time for a factory car weighing 3,100 pounds with a tick over 350 horsepower

It wasn’t just the natural balance which helped him log such a lap. The AP Racing brakes, Ferodo DS2500 pads, adequate cooling, a flat underbody, a decently sized diffuser, double wishbones at both ends, and other features that came from factory contributed to a well-rounded car that could deliver lap after lap without faltering.

The bones were clearly good, but Chris had a few critiques of the car which, though extremely capable, was not quite sharpened enough to be placed precisely in every siThe abrupt lockup was quite exploitable in the slow stuff; bordering on over-rotation, but in faster corners like Bus Stop and Riverside, this characteristic wasn’t as useful. When lifting, the car would rotate as expected, but settling the rear with any throttle would induce a little bit of understeer — even without any weight transfer taking place. For this reason, he found himself overslowing the entries Laguna Seca’s T5 and T10 to ensure he wouldn’t be going for a trip through the dirt.

Beauty Under the Knife

Its suspension design requires less static camber than the E92 does, but there was need for more. With the help of custom upper control arms from Fred Zust at Black Watch Racing, Chris was able to dial in 2.7° up front and 3.5° at the rear. Not much for a full-on track car, but ample in practice, as it turned out.

Along with those custom arms, Fred Zust specced a set of custom Penske 7500 two-ways to sharpen the car and keep the aero platform level over — a must with the elements Chris had planned. With high school friend and founder of Zebulon Ryan Neff leading the charge, the two ran a series of 3D scans to devise the right aero package for the Evora’s sleek but surprisingly draggy body.

Even though the coke-bottle shaped Evora is a sports car, the weight and power produced give it some GT-esque traits which Ryan addressed in his aero design. With this car, he adhered to his typical philosophy for heavier, front-engine cars when designing the aero package: the front gets precedence. Generally speaking, the Evora needs more aero loading at the front axle to get the desired balance with a car like this. So, Neff built the six-inch splitter — which provides the ideal combination of downforce and efficiency — from the front of the bumper and extending all the way to the front axle line, where is blends seamlessly into the factory flat floor.

At the rear, Ryan devised a mounting system which would save Chris from having to hack up the beautiful rear clamshell. Only two holes in the rain gutter were needed to attach the mounts, which connect to a support that bolts directly to the chassis. Ryan’s careful touch is obvious in the design of the two elegant swan necks that pass through the panel gaps between the rear clam and the fenders.

The finishing touches on the first iteration of the aero package were: a set of skirt extensions which widen the surface area of the floor, and bolted on a set of his “ankle cutters,” which manage the inflow of air underneath the car. “The cutters function like a virtual sliding skirt,” he added.

To top off this first round of aero additions, Chris stuffed as much tire as he could fit under the factory bodywork — with 265s up front and 315s at the rear. The car wears its tires well and doesn’t necessarily need a massive footprint, but if the fender wells are wide enough to make room for more, he realized he may as well.

In its second iteration, the Lotus was swift enough to cut seven seconds off Chris’ previous best at Buttonwillow 13CW in the second session that day. A 1:51 is something to rejoice, but he couldn’t be happy too long — at the end of that exciting day, the factory powertrain showed its shortcomings. Simply put, the crankcase ventilation system was not built for 1.5 G and dumped too much oil into the intake manifold; choking the motor and breaking a ringland.

Thankfully, this didn’t mean his budget supercar would be breaking the bank. These Toyota motors have been used in a wide range of cars; making them cheap and plentiful. In went a new motor, to which Chris fitted a set of aftermarket stainless headers for a total of 360 horsepower and 300 lb-ft of torque.

There’s a planned diffuser on the way, as well as an OS Giken 1.5-way differential, which should make the car that much more accurate and predictable in the faster corners. There’s talk of turbocharging the engine for 500+ horsepower, but that’s still undecided.

If Chris does decide to venture down that route, a platform this strong, with this much aero, a friendly balance, and a great deal of mechanical grip should make great use of that bump in power on the track — unlike his old E92. It may be the best test for a versatile chassis like this. Perhaps it will cease being the friendly thing it’s been, but then it’ll be hard to complain when the times continue to drop rapidly. For the money, Penny has provided far more than most cars in this class ever could with similar levels of work invested.

Joe’s RX-7: Long Time Coming

Joe didn’t let fear keep him from starting his love affair with the rotary engine quite young. After a fling with a CRX, he picked up his first RX-7 at 17. This Turbo II, the first of eleven second-gen RX-7s he would go on to own, was a surprisingly swift car that earned him street cred he never asked for. “I once beat this girl’s boyrfiend in a drag race. He had a new Mustang Cobra and I’d just turned the boost up. She came to school the next day telling me about how her brother wanted to kill me. I didn’t get it — it was just a street race.”

He came a long way from teenage antics just as quickly as he got started in cars. The second-gen RX-7 would carry him first into drifting with Nor Cal Drift Academy back in 2004, where he was able to start getting his speed fix in a pro-social manner. Four years later, he picked up a third-gen RX-7 and jumped into track days with the intent of building a dedicated race car, but life intervened.

When his financial predicament forced Joe to take a break, he considered a more cost-effective hobby, but his love for racing won out and pushed him to find a better-paying job. Shortly after selling a lot of Gamestop stock, he put together enough money to purchase a mint third-gen. The only modifications were a set of coilovers, an exhaust, and a v-mount intercooler.

After flying to San Diego to inspect the car, he had to roll the dice. “I knew it was a gamble, but I decided to drive it back to the Bay Area. Not something anyone would do with a thirty-year-old rotary car, but this one was nice enough to convince me it’d probably make it. As soon as I got home, I replaced the OEM suspension — I mean every piece — with adjustable or track-focused parts.”

Along with a set of Tein Flex-Z coilovers, Enkei RPF1s wrapped in 275-section NT01s, and Hawk Blue brake pads, he had made his first step towards making this pristine car into a full-on race car.

Sadly, he’d have to wait longer than he anticipated to experience the RX-7s potential on track, since, after a year of enjoyable, issue-free canyon driving, it failed his first time out on track. “First time to Thunderhill in this thing, and it gave me one full session before it went bang,” he laughed.

With the car back on the track without an engine in its bay, Joe pondered his predicament for a while. As he’d rebuild the motor for more reliability and leave no stone unturned in the process, he figured he’d go ahead and make the cosmetic and aerodynamic changes he’d initially planned for a step much further down the road. Along with a Racebred splitter, he added a Battle Aero wing and both a diffuser and a widebody kit from Shine Auto, as well as their carbon hood.

As he knew what the odds of an engine failure were, he’d planned for the worst and had already picked up a Mazda crate motor, complete with an old-school Turbonetics single kit.

To spare himself any frustration, he had to adopt modern ways. “I went from having a hot rodder’s mentality to a twenty-first-century tuner’s,” he added. After picking a Haltech 1500 ECU, largely for the failsafes it offered him, he had it tuned conservatively by DK at a modest twelve pounds of boost. With a rich mixture and a healthy 300 horsepower at his disposal, he’d have adequate power and some peace of mind the next time he took the car to the track.

“I rely on a heavy premix ratio: two-stroke oil and 101 octane fuel. That’s one of the best precautions you can take.”

All the preparation paid off. During his shakedown at Thunderhill, the water never got above 180 degrees — the v-mount setup and large Fluidyne radiator doing their jobs. The oil, however, was hovering around the 215-mark most of the day. To remedy that issue, he installed a set of thirty-row oil coolers. He’s confident that the car in its current state can handle the next few track days without issue, so he’s moved from focusing on the car and addressed the loose nut behind the wheel.

“The plan for ’25 is to visit all the NorCal tracks, work on my driving, and start competing in Speed SF Challenge. There are other things I’d like to do to the car: a wider widebody, 315s at all four corners, Bosch ABS, and traction control through the Haltech. The plan is to get the car running at its best before I can dump any more money into it.

Wisely, Joe decided to throttle the power output until he’s grown accustomed to big turbo power. Once the next round of modifications is installed and operational, he’ll turn the boost up a bit, but he won’t go crazy. As much power as a tuned 13B-REW can provide, is known first for its handling, and that’s what Joe’s prioritizing alongside reliability. 

His thirteenth-ever RX-7 has been an emotional investment as well as a financial one, but it seems that twenty-odd years of working with rotaries has taught him what the platform can do when all the proper precautions are taken, including the necessary TLC, fueling, and oiling to keep things copasetic.

CSG Brake Pads: Details Make the Difference

Much like tire technology has evolved rapidly in the last several decades, so has brake technology. There are hundreds of brake compounds produced all over the world, and the majority of off-the-shelf brake compounds offered decades ago still exist today. These compounds that may have been great in the past may not be ideal for today’s performance requirements.

CounterSpace Garage have tried to make their mark by putting together a detailed, comprehensive understanding of the entire braking system (across numerous makes and models) as well as the general demands of the entire racing landscape. After spending years testing hundreds of discs, fluids, compounds, and calipers to identify their respective limitations, they’ve been able to satisfy a wide array of performance cars, tracks, and tire compounds.

Contrary to popular opinion, outright braking performance is only one part of the puzzle. Not only are CSG concerned with improving the pad’s outright performance, but they also think about pad control and the context in which the pad will be used. If a pad isn’t suited to the driver’s preferences or the car’s limitations, it will never be used to its full.

To improve control, maintaining consistency is paramount. If the brake pad breaks down, then it snowballs into fluid failure, excessive caliper flex, and excessive disc wear. Consistency also means friction characteristics at different pressure applications, pad modulus through the temperature range, and performance from fresh to the backing plate.

Expending Energy Efficiently

Aiming for a consistent friction material often yields higher pad stiffness, which allows for a more responsive braking feel or “bite.” This doesn’t mean the brake torque is delivered in spikes, which can cause early ABS intervention, but rather with smoother engagement and smoother release. Primarily, the driver feels a more intuitive relationship between his brake application and the way his car decelerates.

Thanks to CSG's custom setup, Gary Wong enjoys reliable, reassuring braking performance in his high-horsepower heavyweight Supra.

Stiffness has secondary benefits including: better pad wear, lower overall heat generation and less heat transfer into critical components like the caliper and hydraulic fluid compared to the existing compounds on the market. A stiffer pad is usually a denser pad, and more material means more thermal capacity.

In order to understand how stiffness plays a role in response, we should use a simple physics equation with the assumption of infinitely rigid structures:

Friction Force (Ff) = Coefficient of friction (mu) x Normal Force (Fn)

This equation helps us visualize the effect of using two different sanding blocks to hold a piece of sandpaper against a sanded surface. A sponge requires more vertical force to generate the same level of friction force at the sanded surface compared to using a piece of hardwood. Now it’s obvious why having a good pad compound can result in better pedal communication and improved control over braking events — it maximizes tire adhesion and improves peak deceleration characteristics more consistently and with less force.

Tailor Made

When we’re trying to assess the level of control their particular pad offers, we consider things like: whether or not they need to build up the threshold pressure, whether they need to reduce their brake pressure carefully like with an aero car. This helps us establish the control objectives,” CSG’s David Leung notes.

“If a driver is dealing with a lot of ABS intervention, a digressive pad can help. As it limits some of that power at higher pressures, it makes it less likely to activate ABS.

Part of Gary Yeung's remarkable speed in his normally-aspirated S2000 comes down to its ability to decelerate, courtesy of CSG.

For cars with aero, a progressive pad might be best. As temperature and pressure increase, breaking power increases at an exponential rate. However, when the aero bleeds off (often very rapidly), this compound makes it easier to reduce pedal pressure quickly enough to avoid lock-up.

All of these profiles are taken into consideration to deliver what is ultimately an intuitive braking experience that allows the driver to focus on other aspects of driving and racing.

To demonstrate the ways in which driver preference factors into the equation, consider just the well-known users of the Supra A90 who’ve partnered with CSG: Jonathan Wong, Jackie Ding, Gary Wong, Allen Patten, Dave Kramer, Drew Turner, and even Toyota Engineering have turned to CSG for their own bespoke setup.”

Thermal Constraints for Different Applications

To get the most from a particular set of pads, some turn to ducting, which helps keep a brake system in its operating window. Some pads need to operate at a much lower temp to generate the performance and better wear (especially pads that generate excessive heat). High levels of heat generation also transfers into the caliper, causing them to get soft, and also transfers into the fluid.

Some pads need heat to perform, which is where ducting can be a detriment, since heat may be required for some friction materials to improve wear consistency in racing situations. Ducting also subjects a brake system to a wider spread of temperatures, which can shorten the lifespan of various components.

Viz paint is used to establish the exact thermal parameters their brakes must operate within.

Ducting does have some benefits especially when you’re operating a spec/homologated brake system that may have undersized calipers/discs (they usually get replaced after each race) and require the brakes to be regulated in a more consistent temperature range.

At the end of the day, ducting should really be a fine tuning tool, not a complete solution to resolve brake issues. It all comes down to designing for the appropriate application and optimizing the performance zone.

Maximizing Both Ends

“We also assess the rear brakes’ utilization. Regardless of whether they’re optimizing their rears to work with the factory bias or they’ve added a proportioning valve, we want the brakes to aid in slowing the car and assisting in rotation.

Jackie Ding's able to make his Supra turn like a much smaller car thanks in part to the well-chosen pads at the rear axle that facilitate usable rotation. 

By maximizing the rear brakes, we can utilize the tire grip from all four corners of the car. Using tire grip from all four tires means better distribution of brake load, maximum deceleration, better wear, and better temperature management to keep the brakes in the optimal operating zone.

A Compendium for All Invested

To take every conceivable factor into consideration is how CSG has been able to develop a wide range of pad solutions. It’s also due to driver feedback and motorsport data, as shared with them by their loyal customers. This information is then filtered down into a range of solutions that meet spirited driving activities to racing at every single level between HPDE and professional racing applications.

"All relevant areas of braking performance must be understood to provide a truly premium product," David adds.

CSG have made countless strides towards finding the right products for most of today’s platforms, They’ve built a compendium of braking data over years through internal development goals, brake dyno work, interacting with their customers, and using their feedback to tailor their products to the customer’s demands. They offer a huge array for different conditions, setups, and for different driving styles.

“CSG is a premium product and the costs reflect that. With that cost, we offer free consultation since we want to meet our customer’s needs and optimize results. All we ask is that they provide data. Ideally, this comes in the form of telemetry, but onboard video, photos, and anything else that can contribute to a clearer picture of what’s happening at the track,” David adds.

The brake system is an ecosystem in itself, which is better understood through constant communication between customer and manufacturer. This interaction is the backbone of CSG’s feedback loop, and only through this and the high-quality data it relies on has high-grade deceleration been made available to drivers of all stripes.

Forced Induction For Track Work: Supercharging Two Popular Platforms

Among E46 M3 and S2000 owners, power is almost considered a four-letter word. The majority of those who regularly lap these cars, for reasons of simplicity and cost, prefer to optimize their car’s handling and braking performance in pursuit of impressive lap times. Also, they typically pride themselves, though usually tacitly, on their ability to lap quickly without a big motor to lean on. However, the ratio of grip to power usually falls in favor of the former with most of these builds, which forces the builder to consider whether a significant bump in grunt is worth the time, expense, and possible hassle.

Two of our fastest drivers decided the relatively cost-effective path of forced induction to determine if more power makes a worthwhile difference with these two popular HPDE platforms.

Seigo Ma had been swooning over the videos of the Arvou S2000, a lightweight AP1 using an HKS supercharger to make a touch more than 400 horsepower. The already capable package could exploit that power bump well enough to lap the technical Tsukuba circuit in a remarkable 53.887 seconds.

Seigo wanted to double his engine’s output, but worried that the famously fragile platform wouldn’t be able to handle it. So, in an attempt to get some much-needed encouragement (and see F1 in person), Seigo took a trip to Tokyo. Three days in, he visited Arvou to consult with Mr. Shibata, who encouraged him to take the plunge.

Back in San Francisco, Seigo started speccing his own HKS kit. He did his homework and chose the option of the smaller pulley needed to make 400+ horsepower. After he installed the kit, he sent his car to Blacktrax for the first pass at tuning his Hondata Pro ECU. They were able to make a knock-limited 350 horsepower at the wheels available over a very narrow powerband. “It only revved to 7,000 safely. That lowered redline, the shorter AP2 gearing, and 4.3 final drive made it a challenge to drive; it required constant shifting.”

To make the most of his new kit, Seigo ordered a higher flow fuel pump, 1050cc injectors, colder spark plugs, and a surge tank with an integrated fuel pressure regulator — all the items needed to run E85 safely. A retune of the Hondata brought power up to a knock-free 420 horsepower available at 8,500 rpm. “Power delivery was like a stock F22, but with a lot more at the top end,” Seigo said.

Even with 285-section rear tires and an OS Giken differential to help meter out that power, the bump in grunt was challenging to manage. “Second gear was pretty much useless,” he added. It also proved too much for the factory gearbox; breaking fifth gear broke on his second track day at that power level. To get himself back on track, he picked up a used AP1 box and a larger supercharger pulley to drop boost and lower the power output.

Relocating the oil cooler made lowered temps enough to run full sessions on moderately warm days.

The AP1 box’s longer gearing combined with the lowered output — about 360 horsepower — helped Seigo get to grips with the car at his next outing. Usable power, strong traction, and drastically improved top speeds has helped him keep up with higher horsepower cars that previously left him in the dust. Before braking for Thunderhill East’s Turn 1, he was traveling at 133 miles per hour — roughly 15 miles an hour faster than he ever had before.

The only notable issue with the car were creeping supercharger oil temps, which he resolved by relocating the supercharger’s oil cooler under the right headlight. With that upgrade, the car has been mostly reliable.

On moderately warm days, the car can run full sessions without issue. Only on the hottest days does it begin to falter, but it still works well enough to run three consecutive laps before engine oil temperatures get too high.

A drawback of running E85 is that combined with the new powerplant, it gets quite thirsty. “I burn half a tank per session, so I’ve gotta bring a few jugs of e85 with me every day. It’s still cheaper than running 91 octane and is much safer for the engine though.”

For Christian Fernandez, power was the last box to be ticked after aero, weight reduction, and a solid suspension setup. He’d already set impressive times with his E85-fed E46 M3, but he wondered if there might be an easy solution to extract a little more from his S54.

Dan from RCrew, Christian’s dependable mechanic, made him an offer on an ESS supercharger kit which promised easy power and little-to-no hassle.

As Christian had already installed a larger pump and 550cc injectors in preparation for corn juice, there wouldn’t be much more he’d need for a successful install.

“Multiple YouTubers who’d used the same kit complained of overheating issues, though. The front-mounted intercooler wasn’t necessary with this entry-level kit, so I decided to take the band-aid solution and install a water injection kit to keep intake temps low.”

On a Dynojet, HTE Performance tuned the stock ECU to handle six pounds of boost from the the supercharged S54 put down 487 horsepower — 157 more than what the atmospheric, E85-fed motor had made on the same dyno.

The bump in power is felt largely at the top of the rev range; making the motor feel similarly linear in its delivery, but notably faster at the end of straights. “It’s pretty easy to put the power down, but the extra 3-4 miles an hour it nets at the end of the straights forces me to reconsider my braking points.”

This bump in straightline speed doesn’t overwhelm the current cooling system, which consists of a larger radiator, an oil cooler, and the water injector. “Even on 80° days, the needle never moves past the ¾ mark!

That said, I’m not sure I’m getting all that peak power over a whole session. It probably needs an intercooler.”

The blower hasn’t made maintenance a nightmare, but it has exposed a few leaks that weren’t an issue before. Running a leakdown test revealed a leak from the valve cover seal and around the aftermarket injectors, which never seat properly and require a washer for passable fitment.

Both drivers are content with their new engine setups, which have proven to be reliable after the little issues were addressed. Seigo bought a usable 150 horsepower and 2.5 seconds at his regular tracks. “So far, it’s been money well spent,” he said.

Christian is content with the improvement, though the M3 was never lacking power in the way the S2000 was. To be fair, the former has gone a step further in addressing all their supercharger’s shortcomings, while the latter has taken a more relaxed approach.

There’s still more to be done before the bare-basic ESS kit offers track-worthy performance, but once it’s sorted, there’s no reason it shouldn’t have that funny effect of shortening straightaways — so much so that Christian will have to start thinking of braking point right after he starts to accelerate.

AP’s Spec Corvette: Ferrari Fill-In For Forty Large

After a lifetime spent racing karts, Outlaws, and everything in between, AP Miranda decided to take a good chunk of the change he’d made over his career as a professional pilot and buy a Ferrari Challenge car. However, he found that the Challenge drivers he met weren’t too welcoming to his outlaw attitude. The series he’d dreamed about for so long quickly lost its luster, and he was curious if there was a better way to spend his money.

AP decided to seek out a cost-conscious alternative among a more welcoming bunch. “I met a couple of the Spec Corvette guys at a Speed SF weekend and they pulled me right in. They were a bunch of renegade guys looking to have a lot of fun — so I signed up and I haven’t looked back.”

Within a few months, he’d built a budget club racer with V8 power, a large footprint, and more than enough performance to keep a driver with racing experience in twin-turbo Ferrari entertained. Best of all, he’d done it for about a sixth the price of his old Ferrari.

The C5 Corvette doesn’t have to be expensive to run. Well, it’s always going to be hard on consumables, but compared to other cars running in the 1:37s on the old Laguna Seca, this version of the C5 Corvette can’t be called pricey. Simple, too — the formula for Spec Corvette is meant to be basic so that the fields can be fairly fat without too much expected from the participants in terms of vehicle prep.

This meant that the competition would likely be close, and so AP put some more money into a knowledgeable instructor to help him get the most from his new old car. He hired Tim Moser, a respected coach with a background in Formula Dodge-Barber, LMP3, and other serious machinery, to show him how to extract all the potential from his low-downforce, high-torque middleweight.

Strengths

Building a Spec Corvette requires little. There is the sole aero item — a three-inch ducktail spoiler from Trackspec Motorsports, but the car is compliant, stable, and predictable without major aero. This is due in part to a set of one-way Penske 8300 dampers and monoballs replacing the OEM bushings. If there’s one thing which the C5 needs to be less of a transporter to the pitch and putt and more of track scalpel, it’s removing the factory rubber.

The factory brakes are fair, but the Wilwood six-pistons are a great budget upgrade, and their rotors will last a year of racing before needing replacement. Even though the minimum vehicle weight is just 3,200 pounds, the Wilwood pads can last six weekends without losing their competitive edge. Retain the stock brakes and you’ll be working on them a lot of the weekend, but the stopping power is sufficient.

In the interest of keeping costs relatively low, the series has mandated a 200-treadwear Nankang NS2R tire, which should last three weekends or so. Considering the power and weight, that’s a relatively long life.

It doesn’t matter if the donor car is powered by an LS1 or an LS6 — either motor shouldn’t have much difficulty making the maximum 380 horsepower and 380 lb-ft of torque at the rear wheels as per the Spec Corvette rules. Both motors are under stressed, consistent, and easy to work on.

There are two options if the car comes with the less-desirable LS1. It can use the intake manifold, heads, and camshafts from the LS6 to make the allowed power, or, if the LS1 is kept totally stock, a set of long-tube headers are allowed. The LS6 only needs to retain the factory headers to make the desired output, so it’s the better choice. Plus, its “batwing” style oil pan is broad, shallow, and sufficient for Spec Corvette usage. In fact, it’s fine for just about any application which doesn’t involve slicks and wings.

However, G-forces and sustained high-revs will still cause oil to accumulate in the LS6’s heads, and to avoid this problem, some use reduced diameter pushrods, some drill holes in the lifter trays to drain oil to the sump faster.

Those are the essentials, though there are a couple preferred changes a cost-conscious owner/driver would consider. Though differential and transmission coolers help extend the lifespan of some of these consumables, they’re not necessary to ensure consistent performance over a single race — or even over a single season. The one last potential issue in this area is, thankfully, solvable with an OEM part. The LS7’s clutch is a cheap and easy replacement for an LS6’s clutch which struggles with the increased power output. Impressively, a Spec Corvette can be built with all new components for just $40,000 — quite inexpensive for the sort of lap times it’s capable of.

“The shocks work pretty well; we barely touch them over the course of a weekend,” Tim says.

Weaknesses

Now, while it would be unfair to say the car leans on its power advantage — which is enough to make it a contender in NASA ST3 — it does have some shortcomings in other areas. The braking performance is fair, though having to run the stock master cylinder makes the pedal feel a little softer and over assisted than a real race car ought to. That, combined with the oft-derided ABS system, forces the driver to learn all the braking system’s shortcomings. “You’ve gotta have the wheel totally straight if you’re going to brake aggressively,” Tim elaborates. Consider that this braking handicap would likely be worsened if the rules allowed the car to have all the camber it could use.

There is the famous lack of visibility to deal with, too. The combination of a low roofline, thick a-pillars, window nets, and a halo seat makes it tough to get a sense of what’s around you. Factor in the C5’s long overhangs and somewhat vague steering, and it might not be the easiest car to place precisely.

Such a small window opening makes rapid extrcationg an act achievable only by contortion artists.

Nevertheless, that’s a short list of shortcomings for a car with so many strengths. Tim’s coaching and Speed SF’s open lapping groups have helped AP feel at ease in the car. “We used the last event at Laguna for passing practice since we’re usually up front at race weekends and don’t get enough naturally. Everyone we drove with was courteous and aware, which made it easy to run nose-to-tail for several sessions that day.

We loved the low-key atmosphere; normally someone complains when you’re driving in such close quarters with someone else. We didn’t get any of those problems with Speed SF, and we got all our time thanks to every session running on-time.”

No major mechanical issues, close driving with plenty of opportunities to practice managing traffic, and a strong series of lap times in the low 1:37s made their last training weekend at Laguna Seca a total success. We hope Tim and AP join us again and give us a demonstration of racecraft in one of the best performance bargains around today.

AP plans to start renting these cars out on an arrive-and-drive basis to those interested in the coming months.

Speed SF Goes Karting: A Thank You to our Coaches

Photo credit: Rachael Hairston Photography

Speed SF’s tiring schedule relies on the enthusiastic support of volunteers, and in an attempt to thank our most dedicated instructors for their time and energy this past season, we decided we’d sponsor them in a special kind of race that gave back to the community.

Miles Kodama, Nate Hackman, and Matt Misencik put in an incredible number of hours this past year, and when asked if they’d be interested in participating in a karting event at Sonoma Raceway, they agreed without hesitation. For all but Nate, this would be their first time racing on Sonoma’s one-mile outdoor karting track.

They’d also get to feel like charitable citizens while they got their jollies. The Sonoma Raceway chapter of Speedway Children’s Charities (SCC) organized the Karting for a Cause event, which donated its proceeds to local children and families in need. Since 2001, the Sonoma chapter has distributed more than $6.8 million to qualified Sonoma County youth groups.

But being good Samaritans was only a small perk in comparison to the pleasure of driving alongside old friends at a top-tier venue in the Saturday sunshine.

Sonoma Raceway’s karting center had recently upgraded their rental kart fleet with new Tony Kart-stickered machines. These nine-horsepower karts weren’t exactly groundbreaking in terms of straightline performance, but being brand new, they generated enough grip to make hustling them on hard tires a bit of a workout in the June heat.

While the standard of kart used that day was nothing new to them, the track was. Sonoma’s outdoor track has been a draw for karters across the nation for the past twenty-odd years. Not only is it set in scenic surroundings; overlooking the full road course below, it remains one of the best designed kart courses in California. The one-mile track mixes technical sections and quick sweepers would make even slightly slow karts very exciting.

The format for the day played a large part in the lighthearted and unpredictable feel of the afternoon. Progression through the day’s six events, each lasting eight laps, was decided by elimination; the fastest four of every seven or eight-person grid would make it to the next race.

From the start, it was clear that Miles, Matt, and Nate had the talent to put them at the front, but despite most of the competitors there not having the same sort of skill, establishing the grid and kart choice through lottery kept things fresh, fun, and challenging. They’d have their hands full making their way through the pack after starting at the rear.

Miles took silver in the first event, Matt won the second, and Nate dominated the third. By the fourth, enough of the field had been eliminated to put the Speed SF drivers toe-to-toe. Matt’s talent for finding grip and managing slow-speed technical sections helped him pull ahead of Miles; the two finishing 1-2 in the fourth event. Nate won the fifth event outright, and for the final race, all three Speed SF drivers were gridded up along with the one threat to their dominance: a young stock car driver who’d flown in from North Carolina.

With the win on the line, the four forgot about driving like gentlemen and began stripping the karts of their new stickers. Unfortunately, the rising stock car driver pulled the mechanic-confirmed fastest kart in the fleet, so the Speed SF trio had their work cut out for them.

Matt started first, followed by Nate, their one adversary, and then Miles. Nate believed Matt would sail off into the distance as he’s proven himself capable of in the past, but Nate found his way past and put his head down to try and stretch a gap. With the stock car star following in his blind spot and taking every low-probability attempt, Nate had to get his elbows out himself to hold his spot. As the two continued to make contact in Man Maker, the course’s fastest corner, Nate decided he wasn’t going to let himself get pushed off and decided to go for broke.

In Man Maker, Nate had been edging towards taking it flat the entire day. On the penultimate lap of the final event, he finally found the confidence to try it. His Hail Mary attempt was matched by the NASCAR hopeful and the two touched at the exit of the corner. Fortunately for our 2023 Challenge S4 vice champion, his rival fared far worse and took a trip into the dirt, giving Nate the chance to stretch a lead over the final lap.

In the end, the Speed SF team came out on top: Nate, Matt, and Miles finishing first, third, and fourth, respectively. After a thrilling day with close racing and near-perfect weather, a trip to the top step of the podium was the icing on the cake. There would be no celebratory champagne on the rostrum, but they’d get a few glasses of grape juice soon afterwards.

After setting their new hardware aside, they relocated to dining space overlooking Turn 3, where they sat around white tablecloths and enjoyed a three-course luncheon with wine pairings from select local vineyards. If they didn’t feel like high rollers then, the view of the stock cars qualifying just feet away for the following day’s NASCAR race did.

Our instructors are the backbone of this business and their efforts have not gone unappreciated. We’re thankful for these three and all the others who spend their Sunday mornings driving to the track when they could be sleeping in, and for their long hours and considerable effort, treating them to a race and a meal was the least we could do.

Tom’s Miata: Frankenstein Fun

Tom’s story began with his Mini Cooper in the fall of 2018. Then in high school, he cobbled together parts from forums and Craigslist Marketplace postings and ended up pushing a little 230 horsepower and 270 lb-ft from the 1.6-liter. It carried him through his track day foray, but the more he drove it, the more it faltered. He couldn’t keep up with the costs, the fuel, and the track day entries.

His friends suggested a simpler car to try and earn his driving spurs with. By parting out the Mini, he could put together the few thousand he needed to pick up an NC Miata with nearly 200,000 miles on the clock. The NC had lived an unloved orphan’s life; moving through seven households before ending up in Tom’s driveway. Somehow, it was still stock when he bought it. This basic package promised regular attendance at local lapping events, even with his college schedule limiting his time and his finances.

Tom didn’t have the means or the interest in going ga-ga with the mod list. The basic package of Feal 441+ Road Race coilovers, RX-8 sway bars, and Cobra Suzuka buckets did him just fine as he was making his way from novice to intermediate. The objective was to get good enough to feel comfortable at the limit and fix what broke.

Fortunately, little did. The only issue in that busy twelve months was the OEM radiator bursting. In the first year of racing, Tom and a few trusted friends logged over thirty DEs on the dependable little Miata. It actually helped him earn a few bucks, too, after reading Engine Management: Advanced Tuning by Greg Banish, he picked up enough to start tuning the factory ECU and starting a side hustle. That money went to his track fees, and it seemed like he’d found a self-sustaining system for himself. All was well with the world until it wasn’t.

After the engine blew, he borrowed his friend’s daily to finish out the final three weeks of his final semester at school, then bought the remainder of a friend’s parted-out NC track car, which fortunately still had its motor. It wasn’t an ordinary two-liter. His friend had swapped in a 2.5 from a Ford Fusion, a budget upgrade with minor architectural differences to the 2.0 it replaced. Swapping it into his car took less than three days.

Unfortunately, the stock 2.5 fell flat on its face at 5,500. With a set of OEM Mazdaspeed 3 valve springs and a set of Xero Limit “Boost” camshafts, Tom was able to raise the 2.5’s rev limit without any thinning of the functional powerband. The 170 lb-ft on tap starts around 3,000 and carries through 5,000, and the power keeps building to the 7,100-rpm redline, where it makes 197 at the wheels.

A comparison of the 2.5 on E70 (red) versus the 2.0 on 91 (blue).

“The objective has been to see how fast I can go without cutting corners or spending much money,” he elaborated. This is Tom’s main reason to try and use as many OEM components as possible. To avoid dealing with the factory rear hubs shearing, he upgraded to a set of hubs from its stouter older brother, the RX-8.

Though it required a bit of custom work to make it fit, the in-the-family RX-8 differential helped tremendously. Better, more progressive breakaway and improved acceleration from a 4.1 final drive originally suited to a torque-free rotary. After this upgrade, the car no longer lost speed going uphill between Turns 8 and 9 at Thunderhill East.

Because the RX-8 differential is taller, in order to sit in the same spot, Tom had to move the alignment area for the studs to sit in the same spot, which meant losing the alignment dowels. Without these, the powerplant frame eventually started sagging after a few months of hard driving. Eventually, this led to the powerplant frame contacting the midpipe under heavy braking and curb hopping. His attempt at notching the powerplant frame was one piece of trial-and-error that didn’t go his way, but he plans to put a set of custom locator plates to avoid this problem permanently.

Currently, he’s fighting the smaller issues like the one above which make the car hard to drive as regularly as he’d like. “Mostly just little gremlins from the engine swap,” he added. Other than that, it's the wallow from the original bushings which make the Miata a bit unpredictable at times. That’ll be relatively straightforward though time consuming.

If his first year out of school is as lucrative as he hopes, he might assemble a new motor to make the MX-5 a real S2000 rival with the following parts: a Fusion’s 2.5-liter Duratec block and pistons, and a Mustang’s 2.3-liter Ecoboost connecting rods and crankshaft, 12:1 compression and an 8,200 rpm redline, he’s hoping for 270 horsepower at the wheels. “It’s going to take a lot of development on my end, but I’ve got a small group guiding me. I’m in good hands.”

Along with the added speed comes a need for better deceleration, so in addition to a set of four-piston Wilwood calipers and RX-8 Sport rotors (which are only $30 per corner), he’s gone and picked another part within the Mazda lineup that takes a little innovation and forum-digging to swap. The RX-8’s ABS system is less prone to engage ice mode. Though this will be another trek down an unpaved path, he’s been given the schematics from others and feels confident the swap will be successful.

“It’s been fun to Frankenstein because I like doing things that not many have done, but I’m more interested in retaining a lot of OEM equipment since I don’t think it will have many issues in the long run. Hopefully, these parts will make it easier to go out and drive more miles. I still need seat time more than anything. Seat time, saving money, and keeping it reasonably streetable have been my objectives. I think I’ve achieved most of them."

Now, I’m considering making it more of a race car since I’ve got a daily now. But until I can afford a truck, there’s no point in making it a total pain to drive. The added torque is definitely enjoyable in the canyons, where I can keep it in third most of the time.”

How many Miata owners can say that?

Cory’s C6 Grand Sport: Safe Not Sorry

He’d spent several years finding his feet in a Mustang, but after his friend was kind enough to let him try their Corvette Z06 at a track day, Cory Smetzler knew he had reached a junction, and although it would cost more, the prudent thing to do was to take a left turn.

The C6’s shape stimulated his imagination, and the performance was already so much more than what he’d been accustomed to; the Z06 in near-stock trim could already outperform his highly-modded Mustang. It was clear that it was time for a major change.

But Cory is a practical person, and making an expensive shift could not be justified by the C6’s soft, curving lines and wide arches alone. Pretty as it was, it was the performance package which convinced him to shell out some more coin, since its improved weight distribution, roomier wheel wells, and dead-reliable engine package promised much more fun and fewer headaches.

A set of American Racing headers bumps output to 470 horsepower and 470 lb-ft of torque at the wheels.

And pragmatism kept him from buying the same model, too. Instead of taking a chance with the Z06’s LS7 motor and its propensity to swallow a valve, he instead opted for the mid-tier Grand Sport, which loses the special motor and the aluminum frame. In their place, the Grand Sport comes with a more pedestrian LS3 and a steel frame, but for the price of less power and more weight, Cory purchased peace of mind.

Though the LS3 isn’t quite the motorsports-grade product the LS7 is, the improvements already made to this particular motor helped Cory forget about lost potential. The previous owner had installed a Dewitts radiator, a FAST 102 mm intake, a Nick Williams throttle body, as well as Doug Rippie Motorsports differential and transmission coolers.

The powerplant ran smoothly in the sweltering summer heat, though the engine lacked that zing and top-end that the other Corvette had, the mid-range torque of the mildly tuned LS3 was plenty exciting.

Mated to a TR6060 six-speed transaxle, the torquey LS3 and its 400-odd horsepower could get the car to GT3RS-speeds surprisingly quickly, so Cory wasted no time giving his new track car the stopping power and safety modifications that it warranted. He doled out the big bucks for an AP Racing Essex front brakes with 372mm rotors and inch-thick pads which guaranteed stopping power, consistency, and long pad life. No sense in taking shortcuts when stopping a heavy, powerful car.

Its accessible mid-range torque is exploitable on shorter courses and still strong enough to reach similar top speeds on faster ones. Surprisingly, the wonderful spread with the right combination of wheel size and final drive make it effortless to keep the engine humming along without the need for many shifts. This is a large part of what makes it so effective at tight tracks.

A 3,300-pound Corvette shows its shortcomings on tighter tracks. The poor motion ratio of the rear leaf springs pushed Cory to double the rear spring rate, which allows for the car to break away more progressively, and the resulting confidence from this predictable sliding helps Cory drive the car with more slip angle than he has with any other car.

The willingness to push a tail-happy car hard in the butt-clenching corners takes more than just progressive breakaway. Cory added a Nine Lives Racing single-element rear wing, mounts, endplates, front tunnels, and a homemade birch splitter added the stability he needed to trust the Corvette in fourth-gear sections at faster tracks like Sonoma.

The current setup isn’t perfect, but it’s nearly there. There’s the matter of weight to deal with, and he’d still like the rear to be better settled, but it is reliable and relatively kind to its tires, and so he’s been able to put in plenty of hassle-free track miles without going through too much rubber. Low maintenance and lots of seat time has been his credo since the start, and he’s hired Joe McGuigan to help put his philosophy to good use. With a little coaching, he’s been putting down impressive times after just a couple visits to Sonoma.

Since his recent move from the Pacific Northwest to Southern Oregon, Cory’s been able to enjoy the temperate weather and make it to track days with more energy and regularity. Seeing as how he’s been able to set impressive laps at circuits that are new to him, it’s certain he’ll be a force to be reckoned with in our Challenge series very soon. We’re happy to have him.

Gordon’s M2: Iteration Cycle

After beginning HPDE during an Apple track day at Thunderhill East, Gordon Mak found a new outlet for his workplace frustrations and his analytical habits.

The Golf R he got his start with proved to be impractical, and practicality being a criteria he’s used to pick his collection of track cars, it didn’t last too long. The Golf’s nannies intervened too much to get closely acquainted with, as the instructor sitting alongside Gordon mentioned several times.

That instructor also encouraged Gordon to look in the right direction, squeeze the throttle with caution, and soften his steering inputs as much as possible. That coach did Gordon an enormous favor that day by instilling good habits in a firm yet friendly fashion. On his drive home, he had a moment to ponder the afternoon’s teachings. Gordon recognized that his new hobby would require two things: a communicative car and the right skillset needed to exploit its full potential.

By the next spring, Gordon was presented with a chance to buy a first-gen BRZ for invoice. The rawness and urgency of a lightweight, balanced car had him hooked, and the first big spin at The Andretti Hairpin had him shook. “Oversteer was a new concept to me,” he said.

Rather than remain intimidated, he tried to suss out his shortcomings then and there. In analyzing his onboard footage following that track day, Gordon could clearly see how ill-equipped he was to deal with the situation. “I just froze; my hands didn’t move at all,” he admitted. 

While some told him it wasn’t the prudent thing to do at that stage, Gordon took a leap and bought an even tail-happier car in the middle of the pandemic. The price was right, and the on-tap torque from a twin-scroll turbo motor and short wheelbase made the GR Supra a lively, exhilarating car with which he could develop his car control skills.

From then on, he committed to the invaluable skid experience of Drift SF, where he could hold long slides, connect corners, and spin without any consequence. “It was sanctioned parking lot hoonery — low credit score activity — that helped me make my first big steps as a driver. By the second event, it all clicked for me,” he said.

“I have to thank Joe McGuigan for teaching me how to slide the car with confidence. Once you move past the pit-in-stomach feeling of losing traction and the belief that you’ll be unable to respond, you can get a lot done. Without all the drift practice, I wouldn’t have felt confident enough to keep pushing,” he explained. 

As fun as it was, the Supra lacked the directness of the GT86. When the dealership he bought the Supra from offered to buy it back for the same price he paid a year prior, he didn’t hesitate. Without waiting, he replaced it with a GR86 and ran eighteen successful events over the next eighteen months.  

The unfiltered driving experience he’d missed so much during his Supra ownership had returned, but not without some adjustment. “After I switched to the GR86, I found myself - for a few events, initially - making unnecessary steering corrections because I had built up so much muscle memory from the Supra always going sideways. It took me a surprisingly long time to get over it, he explained. But even after altering his technique, there was one potential issue he couldn’t get his mind off of. “The ever-present possibility of losing an engine made it difficult to enjoy the car.”

Finding a suitable replacement was simpler at this stage, since Gordon had determined precisely what he was looking for in a track car. He wanted something dependable enough to run full sessions at Thunderhill in the middle of July, something that had adequate performance out of the box, and something which would carry a spare set of wheels and a couple suitcases if needed. Essentially, it had to be mostly turnkey and, if necessary, require only minimal modification. 

Two drivers helped motivate his decision to buy a new M2. First, Randy Pobst’s hot laps in a particular stock car at Laguna, when compared to the PBs set by amateurs in heavily-modded examples of the same model, helped Gordon recognize how big a factor driving skill truly was.

Jackie Ding, the other pro responsible for his decision, had demonstrated what the new M2 was capable of in mostly stock form. While he was worried he might have another Supra experience ahead of him, he took the gamble and sold his GR86 for a brand new M2 in Zandvoort Blue.

Since he recognized the value of seat time, he had less interest in modifying the car heavily than some of his peers. “I’m less concerned with lap times now,” he began. “I’d rather have a few modifications to help me feel calm and confident in the car, but I don’t really have a mod-itch to scratch. I’m more interested in the activities which help me improve as a driver, both on and off the track. If I have an itch to scratch, it’s an itch for self-improvement.”

That said, there’s still some room to make a heavyset grand tourer more at-home on the track, and if he can make a modification or two that will save him in consumable costs, why not? With Millway front camber plates, CSG CP pads, SRF brake fluid, and a square set of Apex VS5-RS wheels measuring 19x10”, he had all he needed to run track days comfortably while keeping his tire bill reasonable. 

The two issues with the car, besides its unignorable mass, are that it’s slightly under-tired and the ZF8 gearbox leaves a little to be desired. “I went a little too conservative with my wheel choice, possibly. It’s even tail-happier than before; I can drift the car in fourth and fifth gear now!” he laughed. 

Some of that is due to the ZF8’s short gearing and the way it shifts somewhat harshly. “It’s easy to spin and lock the wheels on even a slightly damp track.” It’s a lairy sort of car that’s constantly on the verge of oversteer, but at least slide correction is no longer a foreign concept — it’s now something he does without thinking.

Gordon still has some plans for the M2 in the future, but as it’s been happy to run coolly on the hottest days, transport him to and from the track in comfort, and make his track days a little less stressful that the rest’s, he’s content with it as it currently sits. His heart still pulls him towards something lighter and more visceral, but the M2 is about as good a streetable track toy gets. 

And that practical package makes it easier to pursue his main aim, which is to interact with the track community, get enough seat time, and hone his craft as a driver. The fact that the M2 is well insulated helps him hear his coach’s feedback from the driver seat is an added bonus. 

“If you really listen to your instructor, you will improve. I try to remain open minded, test the suggestions coaches and friends give me, and analyze the results. If I can get into an iteration cycle with whomever I’m working with, I’m confident I can find an effective solution to any problem pretty quickly,” he added.

Gordon’s story is one which demonstrates the value of analysis, and, necessarily, the importance of the human element. Rather than descending down the rabbit hole of buying parts to find speed (and justify the costs), he took a different path. He’s searched for the answer to his particular problems and found a repeatable process to keep him active, happy, and stimulated. That’s not something that can be found trawling the forums for an answer.

Joe’s AP1 S2000: Continuing Education

It wasn’t until Joe Drane moved out to California at the ripe age of 38 that he was able to try track driving for himself. Being a natural tinkerer and a bit of a hot rodder growing up, track driving had been a lifelong dream, but the opportunities for that sort of thing in rural Florida were few and far between.

After teaching him the ins and outs of network engineering, Joe started learning the cloud and found a few roles with startups in Texas. This created a focus on execution and continuous learning while also placing high value in data helped him put together a stellar resume in short time. This almost obsessive approach would later help Joe learn at a ridiculously rapid rate when learning the racing ropes.

The Land of Milk and Honey

After relocating to San Francisco to start a new role with Facebook, the assortment of beautiful sports cars lining the streets suggested he might be in the right place to learn to drive on track. He searched for ins on the pages of the local sanctioning bodies until he found an easier, more cost-effective way to dip his toe in the water.

Meanwhile, the need for a new outlet was getting harder to ignore. COVID weighed heavily on him, and while he loved his new job, it didn’t offer the distraction he needed mid-pandemic.

When he proposed running a few lapping days one weekend, his wife not only supported him in his decision, she helped him find an appropriate track car. Incidentally, the two had met at work after Joe spotted her leaving her S2000 in the parking lot. It only seemed right that such a car, the conversation starter, would help him start another love affair.

And so he picked out the cheapest first-gen S2000 he could find. This was several years ago, but even by the standards of the time, this car was affordable — and for good reason. “It was just a mess. It had no rear glass, the check engine light was on, the wiring was a rat’s nest, and the motor was ticking. I spent the winter restoring it, but I didn’t realize just how bad things were until I started working on it.”

Growing Pains

“I ran into some issues installing the aftermarket parts. The radiator wasn’t sitting low enough for the hood to close. I took it into the shop at BlackTrax to have it inspected, and there the mess continued to unfold. The radiator supports were bent, and I couldn’t purchase new ones anymore. I had to source the brackets from two fender cutouts from eBay.

Then we pulled the cylinder head and saw the valve retainers were cracked, there was a ton of carbon on the valves, and two of the cylinder walls were scarred. After ten track days, the transmission blew third gear. Oh man, what a nightmare it was.”

To mend the ailing engine and fortify it for track use, he replaced the block with rebuilt F22’s, then fitted a Radium catch can as well as Mishimoto’s radiator and oil cooler. Not eager to deal with another blown F-series, he wisely spent a few thousand more on a Link G4+ ECU to employ several failsafes and extract everything from the motor — mainly more mid-range torque and a peak of 227 horsepower at the wheels.The Link was then paired to an AiM MXG dash which to give him alerts and relay lap data.

Despite the early hurdles he had to cover, he remained willing and able to push on. The obsessive drive which fueled Joe’s career now had a second outlet; allowing him to research the engineering involved, pick parts, test them on track, and build a more supportive social network than the one which work provided him.

As it gave him a new lease on life, he didn’t hesitate to spend whatever was needed to turn this rough example of an S2000 into something exceptional. Within a few months, he’d added a long list of modifications to try and breathe some new life into this aging chassis.

After investing so much in the performance side of things, it made sense to apply an Inozetek wrap to help the car pop.

Among those additions were an APR splitter, a Voltex Type II wing, Rockstar Garage’s Feal two-way coilovers, and Stoptech C43 (F) and C42 big (R) brakes. Studying hours of onboard footage — namely Nate Hackman’s banzai laps — helped him understand just how much harder he could apply the brakes and how severely late he was getting to throttle.

In the interest of getting up to speed quickly, he skipped the cheap tires and went straight to a set of Yokohama Advan A052s, then wrapped them around a set of 18 x 9.5” Advan Gram Lights.

Though he’d already spent a small fortune on parts, never once did Joe agonize over expense during this introductory period. “I decided to pay for an education in racing since I feel it usually pays dividends,” he said. When his engine tuner Jei from BlackTrax offered to tag along to one HPDE at Thunderhill and teach Joe to study data, he jumped at the opportunity. “The telemetry revealed I was shifting a little too much, so we figured out the right shift points and instantly cut a couple seconds off my PB.”

The car was capable and reassuring enough for Joe to continue pushing, but asking more the car led to the standard Torsen differential failing. In its place, Joe put a Puddymod 1.5-way OSG and found the incremental improvement in power-down and stability motivating enough to invest in one other area that wasn’t quite up to snuff: dampers.

Joe knew the top-shelf option would make the car more quicker, more predictable, and less taxing to drive, so he splurged on a set of Blacktrax-built Penske 8300s. Even without much knob turning, the new dampers revitalized the car and helped Joe find the confidence to commit to the quick corners. “My favorite mod, without question. I dropped six seconds off my previous best the first time out on the Penskes. Worth every penny.”

Continuing Education

Learning to wrench and approach the track from a theoretical perspective helped him progress, but never having attended a racing school, he started to wonder if there were ways to improve his technique post-haste. He enrolled in a few drift courses to study the art of oversteering, and soon felt at ease asking the S2000 to rotate a little more than before.

Both his approach and the S2000’s setup are far from perfect, and Joe’s wise enough to admit that. “I haven’t thought much about adjusting the dampers — most of the time I just leave them in a neutral position and try to drive as best as I can.”

But the results from a relatively short time spent on track speak for themselves. He’s learned at a remarkable rate and, with a little more guidance from the knowledgeable group of friends he’s made recently, he’s bound to be fighting for podiums at the front of the S3 class sometime soon. He still has a few points to play with — and they’ll go towards a Zebulon rear wing, a larger Alumalite splitter, and Professional Awesome tunnels.

Joe’s studious nature has also helped him better understand the endless tradeoffs that building a track car requires. While the major cost associated with getting a rough car off the ground can eat into an aspiring driver’s budget, the peace of mind that comes from driving a flawed, imperfect car can help a driver push hard — harder than they likely would in a pristine example. That’s why he has no regrets taking the rocky but fruitful and informative path he took.

Michael’s 350Z: Take A Chance, Prove a Point

Twelve years with an unloved chassis has given Michael “Stubz” Hillo a unique perspective on taking the underdog route. There are other established, well-paved paths with minimal maintenance and certain outcomes, but they don’t offer a maverick a chance to prove a point.

Stubz took it upon himself to take the unloved 350Z and make it into a NASA ST4 race-winner because, well, he hated the idea of conforming. However, before he started his mission, he was after an affordable way to begin drifting. Nowadays, the 350Z is one of the few Japanese sports coupes that offers the sort of value the budget drifters offered back in drifting’s heyday. Even then, it was pretty cheap.

It was more than just an option for the cost-conscious drifter, as Stubz realized. Beyond low overhead, a torquey motor, and a rear-drive layout, the Z has a lot going for it. It’s reasonably stiff, the aerodynamics aren’t terrible, and the aftermarket is decently sized. It might not be as well supported as the E46 M3, but it offers similar power-to-weight figures and the potential to run respectable lap times at a fraction of the price.

The zeal and the commitment to proving the platform came later — at first, it was cheap fun. Beating up on pricier cars was only part of the pleasure; the steering was full of feel and responsive, the motor responded well to modifications, and the rear end put the power down decently.

Some of that luster began to fade when he tried to turn the Z into something more than a midfield car. The budget modifications no longer seemed to be enough, and so he tried experimenting with the high-end brands which only offered limited support for the Z.

After testing Penske and Godspeed coilovers, he settled on MCS two-ways with 18K springs up front and 9K in the rear. The car still lacks some of the compliance he’d like in slower corners, but it works well enough in the fast sections, thanks in part to Epsilon+ aero, that the compromise is acceptable.

The most irritation has stemmed from the car’s flawed braking system. Persistent knockback issues and lousy OEM ABS pushed Stubz into spending hundreds of hours diagnosing and attempting to find a package that would work.

Plenty of thrown wrenches and a thousand curse words later, he found a set of Stoptech Trophy big brakes that did a reasonable job. Because they moved the brake calipers closer to three o’clock, they mitigated some of the knockback resulting from the steering knuckle flexing. The remaining bugbear was the ABS system, which needed to be retrofitted with the Bosch Mk60 kit from Race Harness Technologies.

Though the braking system works decently these days, Stubz isn’t completely satisfied. Trailbraking has improved, but the outright braking performance hasn’t gotten much better. However, some of that has to do with the weight of the vehicle, which has been hard to lose with conventional stripping methods. “You’ve gotta get pretty creative when it comes to putting the car on a diet. I didn’t want to, but I had to buy carbon. Hatch, hood, front bumper, and headlight blanks from Spinnaker Composites have helped, but the car is still heavy.” he explains.

It’s transformed into a reasonably swift car in recent years, even with the diminishing returns from spending big bucks on primo parts. The 3,200-pound Z has an average of 257 horsepower which is pretty well administered thanks to 275-section Toyo RRs and the aforementioned aero. A broad powerband helps make the car less track-sensitive than some, and, anyways, Stubz no longer agonizes over finding the perfect setup. After several years of head scratching, he sees the Z as a dependable, safe, and sturdy car which is easy to run and satisfying to drive. Going for the gold isn’t his aim any longer — he’s happy with what the 350Z’s speed. Any car that can lap Buttonwillow W13CW in 1:54 is more than just fun — it’s seriously fast.

Striving to perfect the car sapped some of his ambition, but it’s also given him a few notable wins, wisdom, and a pragmatic approach that provides him with peace of mind. His lack of zeal might not motivate newcomers to try and beat the odds, but if they read between the lines, they should realize that there’s nothing with the Z as an entry/mid-level car. It might not carry an ambitious driver to the top of the podium, but its golden era-pricing lowers the barrier to entry. It’ll help them get involved faster — and in Stubz’s view, that’s better than sitting on the sidelines and dreaming of victory.

Sonoma’s Recent Repave Helps Set New Records

Speed SF’s drivers were fortunate to be the first members of the public to experience Sonoma’s new repave — the first in twenty-three years. One of Northern California’s most popular race tracks, Sonoma has been the site of NASCAR, IndyCar, and World Touring Car races over its fifty-five years.

Construction began after Christmas, with ABSL Construction of California milling out over 10,000 tons of asphalt from the track and pit lane, then grinding down the track, repairing old cracks, and laying the new asphalt.

Crack sealing in January.

Construction completed on February 23rd, two weeks before Speed SF was able to experience the new surface for ourselves.

The scenery was verdant, but the repave was far from green at Speed SF’s first full-track event of the season — enabling some of our front-runners to set new records in three of our Speed SF Challenge groups. Even those who hadn’t set new records set personal records. “The track is about three seconds faster than before,” Patrick Chio reported.

S4

In S4, Sean Win-Yepez cut 1.1 seconds off his previous best.

“There is more grip everywhere, but the gains are especially noticeable in T3/3A. There, there was so much grip that my power steering started to cut out!

One observation is that the curbs are not redone, so they now offer relatively less grip than the track itself, whereas before they were essentially about the same as the pavement. So, drivers who didn't use the curbs before will pick up more time than drivers who used them a lot.

My setup has remained pretty similar to last year, and I don’t think I benefited as much in the traction zones as some of the more powerful cars,” he added.

S3

In S3, power helped spread the distance from the previous bests a bit further. Spencer Kimball chopped the previous S3 record, set by him last May, by 2.59 seconds. In the last fifteen months, nothing about his setup has changed aside from some weight reduction. "The new paving really helps with consistency and driver confidence. Thanks to the smoother surface and lack of cracks, you can now take T1 and T2 on proper line instead of diverting your path to avoid surface undulations. I have yet to analyze my data and compare it to my previous run’s, but my lap times were about two seconds faster than my last event at Sonoma in 2023.

Based on my quick and dirty analysis, time was gained in T1, the exit of T6, and the T8/8A esses. One of the coolest features of this totally fresh paving is that my tires looked brand new after the event. Once it's rubbered in, I think we'll be seeing a lot more sub-40 cars at Sonoma,” Spencer predicted. 

S2

In S2, Maxwell Lisovsky was able just to show what his monster E36 is capable of. It has benefited from the most development as of late, but that doesn’t take anything away from his staggering 1:39.3 — a whopping 3.5 seconds faster than his previous best. Now, applying the power cleanly in second-gear corners is almost an afterthought for a sorted track tool wearing slicks.

It seems that, due to gaining something more in the traction zones, the punchier cars have been able to take better advantage of the new grip available. However, even those in the budget cars and the underpowered scalpels will find something to love about the fantastic new surface at Sonoma Raceway. These times bode well for the future, which promises novel challenges for drivers and opportunities to push harder than they ever have before..

Aidan’s GT3: Vision Realized

Photo credit: @z_stills & @tengerphoto

As Aidan Vo moved through adolescence, his affinity for cars carved out a prominent place for him in the San Jose drag racing scene. After he built an all-motor DC2 Integra capable of twelve-second passes, the big magazines came calling. This was the early 2000s, when the tuning scene was enjoying its biggest boom.

Through some of his drag racing acquaintances, Aidan eventually made the leap into road racing. Following his foray at Thunderhill, he started outlining a list of changes the Integra needed to become a corner carver, and for a moment, it looked like Endless might foot the bill.

So Aidan began disassembling the Integra and shelving the parts which wouldn’t do much good around a road course. Halfway through the teardown, he had a change of heart. He parted the car out, sold the chassis to another racer, and decided to hitch himself to the all-wheel drive wagon that’d just reached American soil.

It was in a Subaru WRX STI that really learned how to turn fast laps. His confidence bolstered by the safe, accommodating four-wheel drive, he earned his spurs in relative comfort. Then he switched camps and built a cost-no-object Evo X, which earned several magazine spots. Not only had he become well known and capable around a road course, he’d been rewarded for expressing his inner vision.

As his income grew, he started searching for a new platform. Something with a little more panache — something German.

The big Audi RS4 might not have been at home on the track, but the fit and finish of a plusher, posher machine did spark his imagination. There was something distinctive about it; something which resonated with Aidan and his appreciation for high style. The jump into the Euro market got his imagination running, but, unfortunately, that would be the extent of his involvement with cars for some time.

After living through the height of the tuner craze and enjoying all that the burgeoning market could offer, Aidan stepped away from cars to focus on his career and his growing family. All throughout this quieter interim, he couldn’t successfully quiet one part of his mind. “I missed that buzz; I had to create and build again,” he reflected.

Ten years of car-free focus had done wonders for his finances. Not completely car-free, however; he spent many evenings over that decade drooling over builds his younger self could never afford. When Aidan decided to return to his old hobby, he brought with him the means to realize a plan he’d held for a decade.

“I’ve always been captivated by the Porsche 911 since the 993 generation,” he began. “It’s always had a clean, restrained, understated design — that’s a big part of my aesthetic.”

A few weeks later, he rolled his new 991.2 GT3 into his garage, parked it, and pictured the finished product in his mind with all his planned modifications. The challenge he’d set for himself was considerable, but he had a clear plan and a few connections to help him along.

The Singer DLS was the one machine which inspired the build. “I’m not a Porsche purist who doesn’t believe in tinkering on their car. I see a Porsche as a vehicle that I can use to promote my vision.”

Knowing that the name Manthey was synonymous with Porsche performance, he did what all GT3 owners with grand aspirations for their build would do: purchase Manthey’s complete suspension, brake, and aero package.

There are only a few GT3s equipped with these parts in the Bay Area, and for good reason — one kit costs as much as a newish economy car. Most struggle to justify spending nearly thirty grand on Manthey-tuned KW dampers, solid bushings, brake lines, pads, dry carbon wing, as well as a Cup car’s front splitter, but the resulting crispness and composure is worth it to those with discerning taste and deep pockets.

Perhaps the one downside was that, for all that money spent, the car didn’t look much different than it did prior to the modifications. With so many Porsches looking so similar, Aidan decided to give a nod to the Porsche styling of yore by replacing the factory GT3 wing with a Porsche Sport Design ducktail. He learned shortly after just how difficult it would be to swap out this piece, retain all functionality, all while using OEM Porsche parts — and only OEM Porsche parts.

A hundred calls to local dealerships resulted in the same sad message: “on indefinite backorder.” It took months of perusing before he found an appropriate ducktail from a local owner looking to return his Sports Design-equipped car to stock, but he finally found the part. With the ducktail in hand, he felt as if the build were gaining a momentum of all its own. “Finding that part gave me the confidence to continue doing things the way I want to do them. Everything happened so organically, it almost felt like destiny.”

It’s subtle, but it sets it apart from the rest of the winged GT3s driving around San Francisco.

Of course, the body and the engine underneath would require several tweaks to accept the new boot-lid. Aidan had to source a 911R intake, 911R engine cover, the hinges, every nut and bolts and the oil return lines to allow this new body panel fit snugly. Unfortunately, What would seem to be a simple swap took months and countless emails.

The tradeoff was obvious. “The ducktail definitely makes less downforce than the original wing, which I learned when trying to go flat over Turn 1 at Laguna Seca, but it helps with rear visibility.”

With used 911-money spent on the suspension, it would only make sense to do the same with the powertrain. With Dundon Performance on the phone, Aidan specced out an engine package that would uncork the power of the 991.2 GT3, more mid-range torque and a top-end that reminded him of some of his fastest Hondas.

Dundon provided him with an intake, throttle body, plenum, and headers. JCR provided their titanium race pipes and titanium exhaust tips. The combination of these parts together allows the car to scream like an RSR at redline while keeping a deep, sonorous growl at lower revs.

With the way the GT3 was evolving into something like a racing car, Aidan decided to try and give his car the front track and aerodynamic grip of its race-only sibling, the GT3 Cup. He rung up his contact at Manthey and ordered the primered fenders, flares, splitter, bumper, and crash bar from a bonafide 991.2 Cup car. His painter Jesus matched the new parts perfectly and even achieved OEM paint thickness.

And now Aidan has something that is undeniably his own. Even if it were for sale, his buddies would never attempt to buy it. “‘It’s so obviously his, I wouldn’t ever feel like I owned the car,’ one of my friends told me.”

But is it a show car or a track toy? Aidan doesn’t believe there needs to be any distinction between the two. He’s made steps towards having both distinguished looks and serious performance, and all that he’ll need to do to suit his mood is change a few bolts and reorient the engine fans.

“As pretty as the trunk is, it definitely lacks downforce compared to the Manthey carbon wing. I’ve planned ahead to regain the downforce we all crave at the track. I have a Cup decklid and wing ready for track days. That arduous ducktail swap was done specifically to allow swift decklid swaps when it comes time to take the GT3 back to the track. All you have to do is reorient the fans to fit the subframe brace. After that, you’re off to the track.”

At this point, he feels he’s nearly realized his vision. Aidan cannot see himself selling the car, but that doesn’t mean he’s going to make it a collection piece. Instead, he’ll put it through its paces, enjoy it as both a driving tool and a rolling piece of art, and hope that his commitment and the car’s obvious quality will inspire the next generation of speed freaks with an eye for design.

Walter’s Sentra: Lifetime Obsession

A lifelong Nissan fan and a crew member for an old NASA team running an SE-R, Walter seemed destined to pick up this particular Sentra. His family had brought him up on Zs and Maximas, so when Walter turned 16, he bought his first car, a 1991 Sentra.

That sowed the seed for the next several years. Inspired by Need for Speed, he started tuning his Sentra and soon became a knowledgeable voice in the community as well as an in-demand mechanic. His reputation opened the door to crewing positions for several big teams running in NASA’s SE-R Cup series back in the early 2000s — some of which even ran in the 25 Hours of Thunderhill.

In 2003, Walter stepped away from cars to focus on family. That break lasted for fifteen years. After that long interim, he picked up an E46 M3 and started driving himself. As good as the BMW was on the track, the love for the old Sentra, now mixed with his recent racing experiences, led him to consider building a special Sentra for racing. However, he couldn’t spare the time he once could, and so he hoped something half or wholly-built would pop up in the classifieds.

When an old friend reached out to Walter with news of a special car for sale, he felt like his stars had aligned. Not only was this particular Sentra built by MotoIQ’s Mike Kojima, but it had been the brother of a car Walter was familiar with — one which had been raced in SE-R Cup back in the day.

That particular car from his crewing days was named “Dog I.” This was “Dog II,” the sister car. The two had been given their monikers from their Petco sponsorship; they had pawprints plastered all over them during their racing days. The latter wasn’t used much in Spec SE-R, but it had seen some action in the Pacific Tuner Championship ten years ago. Since then, it’d been stored and taken out for the annual track outing. The price was right, the build quality was obvious, and the decision was easy. Walter drove his truck and trailer down to LA that weekend and began a new relationship that joined his past with his future.

Like its sibling, Dog II is built upon a body-in-white build with all the right parts. The motor, a 2.1-liter SR20VE with 11:1 compression, produces 200 horsepower and 170 lb-ft of torque on a 50-50 blend of 91 and 100 octane fuel. It’s a peaky motor, but with only 2,600 pounds to push along, it makes do.

An oversized Koyo rad is part of the beefy cooling system that helped Kojima run the car comfortably in desert heat.

Handling comes courtesy of a square set of 235/40R17 NT01s wrapping Volk TE37 wheels and an intricate cage connecting all four shock towers. Ground Control coilovers, plenty of front camber, and a bump steer kit help the car follow every minor steering input. The final touch, a little bit of rear axle bending to toe the rears out slightly, contributes to the Sentra’s immediate turn-in — the kind that is vital in a front-drive sedan. “Super oversteery” were the words Walter chose to describe its balance.

The car was just about perfect. Aside from updating the safety equipment, Walter felt it needed nothing. That was until he drove it on track for the first time and struggled with the peakiness of the motor. Despite the SR20VE’s variable valve lift, it isn’t quite as tractable as he wanted. So when picking out a new Nismo LSD, he specified a 4.75 final drive to keep the engine in its sweet spot more of the time. And like that, he was done with modifying it.

The problem with a car like this, even a relatively simple car that’s nearly completed, is that it requires a trained race shop to maintain it. He leaves it to Tarek at All Automotive in Mountain View. “They have the suspension geometry expertise and motorsports experience needed to direct the continuing development of the vehicle as well as continue the maintenance needed after every season,” Walter adds.

Now that the Sentra’s up to date and running reliably, he hopes to put in as many track days as he can. It hardly uses its brakes; the Wilwood four-pistons and 11.75” rotors are understressed. For how fast it is, it’s remarkably easy on consumables. It’s still on the same set of tires the car came with, too.

He played a supporting role for many years, but once the ball was rolling and he was able to sit himself in the seat, things have gotten steadily better. His racing education helped him make the right decision when it came to buying a purpose-built car — one which has given him the opportunity to put in his 10,000 laps without having to regularly wrench on the car. The fact that he’s finally getting to hone his driving skills on track in such relaxed fashion is sweet, but it’s not quite as sweet as being able to simultaneously revisit his tuning heyday and witness his racing future expand.

Speed SF Challenge 2023 RECAP

Speed SF’s committed clan of drivers kept the Challenge season full of excitement this year. The competition was fierce throughout most of the classes, the fields were full, and the number of new course records — nearly a dozen — proved the rapid rate of evolution, both from car and driver.

In S1 and SX, Steve Melson was our standout. His more-is-better approach to track days; running his McLaren 765LT, his Audi R8, and his Mercedes GT S simultaneously, proved he knows how to make the most of his (seat) time.

Unfortunately, his busy schedule prevented him from attending the required number of events to qualify for a podium place, but his occasional appearances were filled with laps thanks to the triple-session approach he’s made his own. Still, even with relatively few appearances this year, Steven was able to set a new S1 record at Laguna as well as a new S2 record at Thunderhill West. We look forward to seeing him next year.

Steven’s McLaren is, without a doubt, the fastest stock car currently in our ranks.

In S2, George Brooks, a newcomer to our series, established himself as a front runner from the start. His potential was clear after winning the second event, and the combination of consistency and his C7 Corvette’s acceleration kept S2000-driving Champion Gary Yeung on his toes. George's early-season pace wasn’t a fluke, either – he proved himself quick at numerous circuits with front-running positions all throughout the season. In fact, George did not miss a single event this year.

His commitment paid off; culminating in a double-points victory at the season finale at Laguna. Though George’s effort could not beat Gary’s outright pace in 2023, we have no doubt George will give Gary and the rest of the S2 contenders hell this year.

A simple Corvette and good support helped Thomas find his potential quickly.

Newcomer Thomas DiGioacchino rounded out the podium. His C5 Corvette and his driving improved considerably over the course of the season, and his five podiums stand as testament to the fact that, even with relatively little experience, putting yourself in good hands can help you hone your craft quickly.

On top of the regulars, there were four reclusive geniuses making up the ranks this year — each of their one-off wins kept everyone guessing. Seigo Ma (S2000), Steve Melson (Mercedes GT S), Kai Anderson (Camaro ZL1), and Tailai Lihe (Supra) might not’ve been in attendance every weekend, but they didn’t need to be to stand at the top of the podium.

In S3, we saw the closest title battle among any of our classes. It was Spencer Kimball and his well developed E92 M3 who eventually took the crown, but Legend Brandenburg in his modestly tuned Supra kept most of us guessing. The title wasn’t decided until the season finale — where the difference between these two was a mere eight points. Legend took the win that day, but it wasn’t enough to offset Spencer’s dominant performance from February to December.

Spencer’s M3 has had all its issues addressed and now puts in remarkable times consistently.

Tailing closely behind, mainstay Joe McGuigan in his recently sorted IS-F made the last step of the podium, and, it should be said, kept Legend and Spencer honest throughout the season. Also worth a tip of the hat was Ken Cemo, who attended every event and drove his Camaro exceptionally well. His upbeat attitude and commitment slate him as a future podium finisher.

Sean’s tidy driving made him the dominant driver in S4.

The S4 field was by far the largest, with thirty-three competitors and a close battle between S2000s at the top three steps. Sean Win-Yepez followed the wise words of Aki at Blacktrax and kept his S2000 simple and the changes minimal. Additionally, Sean started running double sessions to maximize seat time. This allowed him to run most of his best laps in the Gold Open Passing group, which reduced the pressure and made it easier to set a hot lap. With seven wins and eight new lap records at the end of the season, Sean’s holistic approach had clearly paid off.

While Sean set the S4 standard this season, it was wildman Nate Hackman in his milder S2000 sliding close behind and providing the entertainment. His flamboyant driving style was not merely exhilarating to watch, it was seriously fast; his bests often just marginally behind Sean. Maybe Nate will max out his allotted points in 2024 and give Sean an even tougher time.

David Haro snuck in a solitary win — another gold for the S2000 clan. We anticipate the other S4 contenders — Scott Smith (987 Cayman) and Patrick Chio (E46 M3), winner of the S3 season finale — nipping at Sean and Nate’s heels throughout the coming season.

Patrick (M3) added a passenger seat in order to run in S4 for the final event and showed most of the class his heels.

In S5, the two heavy hitters in the lightest cars traded positions all season. In addition to setting a slew of records at Thunderhill, Tyler Packard took his RX-8 to the title, but that was not certain until the final few rounds. S5 is anyone’s game as long as they show up frequently, as Patryck Sworonski (NA Miata) proved with an equally impressive series of wins and seconds. In the end, Tyler attended one more event than Patryck, and that made all the difference.

We hope to see both new and familiar faces ready at Laguna Seca on February 18th, where this year’s Challenge will officially begin.

On a technical note, our Competition Director Scott Smith has made a few modifications to both base and modification points to further converge on competition parity.

Passing Etiquette: Making Space and Saving Face

Photos (unless specified otherwise): Trevor Ryan

Overtaking is a tricky business, and learning how to pass decisively and safely takes time and practice. It pays to err on the side of caution — especially with unknown drivers. After all, squabbling for position isn’t the most judicious thing to do when there’s no prize on the line. Nobody wins a track day.

As a general rule in racing, the overtaker must present themselves alongside the driver in front — typically with the overtaking driver’s front wheels ahead of the overtaken driver’s rears before the turn-in point. This way, they’re able to see the other driver through their peripheral vision. Studying one’s surroundings and knowing where other cars are at all times is necessary to become a capable track driver.

It pays to be seen. Credit: CC-by-2.0/MIDWST.BLUR

Of course, this is a rule followed in wheel-to-wheel racing. With Speed SF, the passing car must have its front wheels in-line with the passed car’s front wheel before the beginning of the braking zone if they want to attempt a pass. It’s worth giving everyone a little more room since nobody can truly win at a track day, after all.

Our aim is to give all our drivers their own space and help the faster drivers safely navigate the slower traffic so nobody gets held up.

To give assertive advanced drivers the leeway to pass freely while allowing novices time and safety to ease their way into it, we have outlined some hard and fast rules for our various run groups. For those groups with stricter passing rules, like Green and Blue, the process of passing is made as simple as possible.

Novice Group (Green)

Responsible novices dedicate most of their mental energy to driving their own car, so they likely lack the bandwidth to watch their mirrors while driving. For this reason, we only allow passing on the designated straightaways — never through the middle of a corner — to simplify the mental burden. The courteous driver being passed should lift off the throttle to make life easier for the passing driver. This really helps when overtaking in a Miata.

When the driver being passed decides to lift off their throttle, they give the passing driver more room to complete this overtake prior to the braking zone, which is our second requirement. The passing driver should not be pressured into squeezing themselves down the inside at the turn-in point. Just because someone, especially a novice, gives the point by does not mean that a pass is possible; the passing driver must carefully judge whether it is going to work. If it’s doubtful the pass can’t work, back off — nobody wins a track day.

Generally speaking, we like the driver being passed to allow the passing driver to rejoin the conventional driving line before turning in. If they insist on turning into the corner from an inside line (ie. a line closer to the apex than the standard line), they must navigate a shorter radius and therefore reduce their entry speeds accordingly.

Because the novice’s situational awareness isn’t as great as a regular who instinctively checks their mirrors, we require the passing driver to wait for a specific gesture from the driver ahead. By leaning their left hand out the window (or right in a RHD car) and pointing at the portion of the track they’d prefer the overtaking driver to use while passing, they give a sign of recognition and avoid confusion. Wait for a clear signal, and preferably before a longish straightaway — it’s safest and easiest to pass there.

Intermediate Group (Blue)

Even with their experience, we want members of blue group to follow the same passing rules as the members of green.

HARD RULES: GREEN/BLUE

Point-by passing is required at all times. Under no circumstances is passing in the corners allowed, and passes along the straights must be completed before the braking zone.

Point-by Recommended/Mixed Group (Yellow):

After a dozen days or so, driving alongside others at a quick pace is no longer terrifying like it once was. We try to encourage these drivers to be assertive with their car placement so as to begin the two-part process of an advanced pass. Both parties must be aware of one another, and as long as there’s enough room to overtake safely, we allow passing without a hand signal. Though a point-by is still recommended to make sure everyone is aware, it isn’t required.

There are other ways to communicate reaching an arm outside the window. For instance, the driver being passed taps their rear-view mirror prior to the turn-in point (a common acknowledgement). This indicates that the driver attempting the pass is seen and will give way. The driver ahead can also offer a corner without signaling by slowing than necessary before turn-in, usually off the ideal line. If the driver behind sees the “door opening” and the driver ahead taking an odd line slowly into the corner, they will know they’ve been given a chance to pass.

When overtaking and turning in on a tighter line, remember more braking pressure (if braking is necessary) is likely required.

HARD RULES: YELLOW

The fundamental skill required to run in this group is strong situational awareness. Drivers are allowed to pass anywhere, but only at a moderate pace. Point-by passing is recommended, but not required. Exercise caution and make sure to read the driver ahead before attempting a pass.

Open Passing Group (Red + Gold):

Highly experienced drivers aren’t protected by such rules, which means they need to read the subtler signs of a driver giving way, learn how to pass decisively, and how to present themselves so as to be seen.

To run successfully in the Open Passing Group, you must know how to improvise with car placement while keeping the general level of grip in mind. Even while driving through a corner side by side, both drivers must be able to react and, hopefully, anticipate the other’s move.

Limited visibility and reduced grip make overtaking in the rain even more challenging. Remain patient and, due to the tricky conditions, avoid forcing the issue.

Of course, open passing doesn’t mean fighting for position like it would in a true race setting, but the increased level of competition typical in this run group

Assuming both parties can recognize each other’s position on track and drive in harmony, these sorts of overtakes can be done safely. They do, however, require a good deal of spatial awareness, decisiveness, car control, and forethought. For that reason, we only allow drivers with over twenty track days under their belt (or those holding a racing license) to join this group.

HARD RULES: RED/GOLD

Twenty-plus track days or racing license needed to partake. Must be experienced with open passing. No passing restrictions as long as drivers exercise good judgment.

Final Thoughts

Cooperation is the name of the game, so try to wait until a definite sign is given before attempting a pass. Make sure there’s adequate grip available to take a tighter line than the conventional line if that’s what the situation requires. The tighter the line, the more deceleration prior to the corner is required. Trailbraking helps here.

If a train of cars ahead makes life difficult for a faster driver bringing up the rear, they’re advised to pit momentarily to establish a gap. This makes life much easier and offers a better chance of achieving a personal best.

When deciding whether or not to attempt an overtake, remember that the passing car is always responsible for ensuring a safe pass. Even if the car ahead closes the door on the driver behind, it’s the latter’s fault. Leave a little space whenever possible and never squeeze somebody on a track day.

Keep eyes up at all times, scan the environment for faster and slower cars both and behind, and try not to fixate too much on rolling speed into the corner during an overtake. Instead, prioritize a strong exit. Well, the beginners should try to do this to avoid sliding off when overtaking on the inside. The experienced drivers know that, in racing, sometimes getting ahead of the driver in front is all that’s needed; an overtaken driver can’t always respond if the overtaking driver exits the corner slowly. Again, that’s racing, and this is track day driving, where the objective is to bring the car home in one piece.

Lastly, remember that there’s nothing to win here. Track days exist to help people gain experience running independently, so giving way to a faster driver when they’ve demonstrated superior speed is a mark of maturity. Yes, it might sting, particularly if they’re in a much slower car, but leave some room for humility and open the door — following a faster driver closely can be the best sort of instruction anyone can get.

Hubert's MKIV Supra: Soft Spot

Like Ken Yu, Hubert Chan first got a taste of speed on two wheels. His motorcycling antics with his cousin Wil sowed the seed, but it wasn’t until one of Wil’s dearest friends gave Hubert a taste of acceleration that made even a 600cc bike feel a little lackluster. The stoplight-to-stoplight sprints in Phil’s modified fourth-generation Supra Turbo had Hubert hooked. “It just never stopped pulling,” he said.

However, Hubert wasn’t pushed in the direction of drag racing — he had an affinity for corner carving. An E30 M3 seemed to him the coolest cornering machine in his price range, but he struggled to find the right one. Eventually, he decided another platform might be more accessible, so he gave the big Supra a chance. This was 2013, back when both these iconic cars cost half of what they do today.

The Supra had left an indelible mark on him, and though not many had taken them to the track, his knowledgeable friends signed off on the Supra as a worthwhile sports car. When Hubert found the online listing for a clean, reasonably priced, and unmodified 1994 Turbo, he bought a one-way ticket to Salt Lake City and drove it back to the Bay, dreaming of future modifications the entire way.

The Supra Turbo had proven itself as a stellar road tripper; comfortable, quiet, and still torquey enough to pass anybody quite easily. However, it was a little on the boaty side, and Hubert sought out a few ways to improve the footwork.

First came a set of Fortune Auto 500 coilovers, and the resulting agility proved that the car was more versatile than its reputation had led him to believe. The Supra’s long wheelbase didn’t feel like an encumbrance on tighter backroads, and the way it sat securely over bumps and cambers made it quite confidence-inspiring.

The foundation was there for more power, which Hubert always knew would be the most exhilarating part of tuning this new toy of his. The promise of easy horsepower encouraged him to amass a large collection of engine parts over the course of the first year. By the time he’d had it for twelve months, he was ready to move onto the second chapter and double the power output.

With the help of mechanically-inclined friend, they pulled the factory turbochargers and replaced them with a log-style cast manifold and a Precision 6266 turbocharger, then fitted Kelford 264° cams and a full 3” Tanabe Medallion Exhaust. With some meth injection and a safe tune of the AEM V2 from Lawrence Shipman, the motor made a healthy 580 horsepower on 91 octane.

With the way the Powerhouse Racing turbo kit emphasized low-end torque, it became challenging to turn that into propulsion. To address the wheelspin issues, he followed the forum recommendation to replace the factory torsen with a TRD 1.5-way differential and increase the rear tire size to 295s, which he was able to do via widening the factory rear wheels.

For the final touches to the footwork, Hubert had consulted the Supra community for an appropriate sports alignment, but upon taking it to Elite to have it aligned, Melody Cannizzaro suggested a few alterations to his provided specs. With additional toe-in at the rear, the Supra felt reassuring and stable; enough so that Hubert was comfy stepping on the throttle in second and third gear. No longer was he hindered by the big torque, which gives relatively little warning before it hits.

The Supra had established itself a capable cruiser and a competent canyon car, but Hubert was most interested in seeing what it was like in an environment where he could really stretch its legs. It wasn’t long after that his friend Janning encouraged he take the Supra to Laguna, where he met his friend Samson, another track driver who’s been instrumental in getting Hubert up to speed.

After a few spins and some big slides, Hubert began to get a sense of just how much of the power he could use in Turns 2 and 11. The power must be applied gently in the slower corners, but it will put the power down in third, assuming the car is mostly straight. “The car was definitely driving me that day, but I didn’t care. I was addicted!” he exclaimed.

Over the next few events, Hubert began addressing the handling problems only apparent after a few fast laps. It was still a little too floppy from factory; the annoying targa top would flex to the point of requiring readjustment after every session.

Hubert parked beside his friend and mentor Samson’s M3.

Titan Motorsports’ four-point rollbar, reduced the flex and the need to fiddle on the targa between outings. Still, it remained too soft to transition crisply, so Hubert installed a set of SuperPro polyurethane bushings at the critical points in the suspension, Titan anti-roll bars, and a TRD strut bar. It’s tauter than it’s ever been, but it’s still a little on the comfier side. As a car which sees more street duty than track action currently he’s content with the setup.

Its ability to cruise to and from the track in total comfort isn’t something he’s willing to forgo in the name of going faster quite yet. The power is more than adequate, the car is controllable, and the engine doesn’t show any signs of stress. Essentially, it’s barely breaking a sweat with such limited lapping.

“I’m happy with the Supra in its current state for now, but once I get a little more comfortable pushing it, I might improve the brakes and the suspension.

It’s just an easy car to live with, and I’m afraid of ruining that. Plus, it gets so much attention in the pits. Some people ask me why I risk driving such a rare car, but I think it’d be wrong to keep it in a garage. Most people think it’s only good for drag racing, but the Supra is a great performance car — it’s very much at home on the track.”

Brian's BRZ: Painful Lessons in Lubrication

He’d spent years dreaming of driving on a track. Brian Armstrong had grown up hearing racing tales from his late uncle, a former professional stock car racer; and grandfather, a racer, mechanic, and performance engine builder. Even coming from good stock, Brian hadn’t really found a door into the world of motorsport himself. The opportunity finally arose when he relocated from New York City back to his native California in 2021.

Now in a more car-friendly environment, he decided to get a more track-oriented car and explore performance driving. It didn’t take long to choose a vehicle. He wanted a front-engine, rear wheel-drive platform and relatively low cost of operation. It was either the newly released BRZ/GR86 or the latest MX-5. The stars aligned when he found a 2022 BRZ in World Rally Blue in transit to a local dealer for MSRP. He put down a reservation site unseen and picked it up about a week later, in early December 2021.

In Good Company

He started with autocross, attending 4-5 events before graduating to track days. After a couple events, he found 86 Challenge, a local time attack series dedicated to the 86 platform and sponsored by SpeedSF and GT Radial. He started participating in the Stock Class, which allows only minimal modifications to the car, with the intention of setting a level playing field with a low cost of entry to be competitive. “The stock class appealed to me because all the cars are set up the same, more or less. That means your pace is primarily dictated by driver skill.”

The few modifications allowed in street class help showcase the BRZ’s brilliance out of the box; there are no drawbacks to having such a short list of legal upgrades. His car has the following modifications:

• Pedders Offset strut mounts and top camber bolts for -2.5° of front camber

• 17x8” 949 Racing 6UL wheels wrapped in 225/45R17 GT Radial Champiro SX2 tires

• AP Racing Endurance front BBK with Ferodo DS1.11 pads and Carbotech XP10 pads in the rear

• 7mm Perrin front spacers

• ARP extended studs

• GR Performance Exhaust

And he’s added a couple ergonomic tweaks: a shift knob from Ansix and, for a little added support, he inserted a section of half-inch yoga mat into the factory seat bolsters. It’s surprisingly effective!

In addition to competition, he also found community in 86 Challenge. Having faster drivers as benchmarks is helpful, but the participants also freely share information to help each other improve as drivers.“We record our telemetry data on AiM Solo 2 or RaceChrono data loggers, then share the data on Google Drive, so we can compare. It’s all voluntary, but we all want to help each other get faster.”

They were also interested in diagnosing some of the BRZ’s from-factory flaws. “We’ve also been collaborators in trying to understand and improve the reliability of the oiling system in the 2nd generation BRZ/GR86,” Brian continued. Two 86 Challenge participants had added oil pressure sensors to their cars and started documenting oil pressure drops on right hand corners as early as November 2022. After several drivers in the broader 86 community suffered engine failures on unmodified engines, including a couple who Brian knows personally, this became a bigger focus..

Brian’s analytical strengths helped him delve into the data and contribute to this effort. He instrumented his own car, with help from 86 Challenge drivers @nostreetracing86 and Miles Kodama, and published a video on YouTube explaining the issue with evidence from his car and two others. He also volunteered to test a prototype baffle from Killer B Motorsport and later Verus Engineering in hopes of finding a simple way to mitigate oil starvation.

Ironically, his engine blew the day one in-depth article he’d contributed to was published.

That expensive afternoon at Thunderhill East went smoothly until it didn’t. Initially, when Brian saw a pressure drop to 0 PSI, he first thought a sensor had failed. When he heard that terrible telltale shuddering sound emanating from his engine bay — the one he’d heard so many times in the big-hit failure videos on YouTube — he knew it was catastrophic.

Thankfully, fellow 86 Challenge driver Kevin Schweigert offered Brian space in his garage to suss out the cause of his FA24’s failure. With the pan on Kevin’s garage floor, Brian took a peek. It took two seconds to determine what had happened.

A small piece of metal had broken off the baffle and blocked the oil pickup. “It was a one-of-one prototype build, so these types of things can happen. Verus immediately accepted responsibility and said they would help with the rebuild.” They covered the cost of a new FA24 long block and, through generous donations from the community, Brian was able to cover the cost of labor and additional parts needed for the rebuild.

Second Stab

During this rebuild, Brian took advantage of the opportunity to make some improvements to his oiling system to try and increase durability and decrease flow restrictions, which can decrease pressure to the crankshaft.

His old oil cooler lines had been rubbing on a sheetmetal seam near the driver’s side headlight and there was insufficient protection from abrasion. It could have been a serious issue if not addressed.

Following advice from other 86 Challenge members, he decided to replace the lines with custom built Goodridge 910 AN hoses—as used in the GR86 Cup Car. These kevlar-braided lines are more abrasion resistant, but also feature a larger internal diameter, for less flow restriction. He also increased the size of the oil cooler core with the hope of reducing temps and reducing flow restriction.

His shakedown of the new engine, oil cooler, and a new generation of oil pressure instrumentation hardware at a recent SpeedSF event was auspicious. Everything worked well, Brian was at ease, so he pushed a little harder than normal set a new PB.

Brian’s committed to the cause. His continuing work with Verus aims to solve this starvation issue and the pair is planning to test a new prototype in January. They now believe the primary issue may be related to the oil returning too slowly from the heads to the oil pan, which the prototype attempts to fix.

The community support and innovation from the major aftermarket players have encouraged Brian to continue chancing his baby in an attempt to solve the problem which worries most BRZ owners. Undaunted by the big bang this year, he’s planning on returning to Stock class in the 86 Challenge in 2024. Consider it a testament to a lovely atmosphere among cooperative drivers and an exhilarating platform worth taking a few risks for.

Thomas' Corvette: In Good Company

Finishing out his senior year of high school, Thomas DiGioacchino listened to a friend’s suggestion and scrounged the money together for his first track day. Crap tires, decent weather, and a near-stock Mustang GT were all he needed to find that thing that’s been steering his life for the last five years.

Thomas decided to pursue the mechanical side of things and enrolled in Ranken Technical College’s High Performance Technology course with a focus on Chevrolet LS engine design.

That emphasis allowed Thomas to build a motor for a car he hadn’t yet bought. It began with an iron-block LQ motor and LS1 heads, and as the LQ block only displaced 5.3 liters, he bored and honed it out to 5.7 liters to fit the LS1 head. With forged pistons and rods, oil pan baffles, and the other pieces that made it a 500-horsepower workhorse, he unknowingly set the tone for the rest of this build.

The car itself came next. During his final year at Ranken, he found himself a base 2002 Corvette within his price range and tucked it away in his side yard until graduation, when he loaded up his truck with his furniture, his motor, and began his drive from Missouri to his hometown.

Back in San Mateo, he reached out to his then-limited network for car parts and, with some luck, gainful employment as well. As he’d relied on Elite Performance to direct him towards a few bolt-ons for his Mustang, they were the natural resource to consult. One day, while speaking to Elite’s Melody Cannizzaro about getting his Corvette aligned, she provided up with a job opportunity. He didn’t have to think twice.

Working with Elite gave him access to one longtime customer who happened to be offloading some go-fast bits from their recent Corvette build. Thomas was able to grab a set of Titan 7 T-S5 wheels for peanuts, and then came big brakes, bushings, and a bucket seat. Soon, the plans for keeping the Corvette tame and civilized went out the window.

Wisely, he went for safety equipment next, and decided that this car would only help him become a truly quick driver if it was reliable first and fast second. “I knew that seat time would be the priority if I was going to run with guys like Gary Yeung,” he said.

That said, it would be silly not to make use of the big motor sitting in his parent’s backyard. Soon, it found a new home in the Corvette’s engine bay, and Thomas took the half-built C5 to its first track day, where it ran without a hiccup. It ran well the second day, too, as well as the third. Clearly, he’d paid attention in class.

Aside from the minor repairs any twenty-year-old car needs, it was the epitome of dependable. His focus was on learning to drive the car better, but, to his credit, a C5 on stock suspension does leave a lot to be desired. It would lean excessively, and under trail braking, it had a habit of snap-oversteering.

After several months of saving, Thomas bought a used set of JRZ two-ways. While he was at it, he pulled and refreshed the entire drivetrain, then upgraded the springs and clutch packs in the OE LSD. Those modifications made the Corvette much more progressive at the limit, regardless of whatever cheap tires he happened to be running.

When he found the time to fine-tune the suspension, he increased the rake to increase rotation at corner entry. A square 295-35/18 setup was the cost-conscious tire option, and he stretched every set until the cords showed. Still, the car was mostly neutral with a hint of understeer in the faster stuff thanks in part to his APR GTC-300 wing.

As his confidence grew, he started to recognize that driving around on worn rubber was no longer the training tool it had been, so he sprung for a set of AR-1s and turned his first sub-two-minute lap at Buttonwillow 13CW. “I had to fight it the whole way around, but I got 1:58. A sloppy 1:58, but still,” he said.

Good tires helped, as did having a hare to chase. With Gary Wong driving his S2000 off into the distance, Thomas was able to see where he could push harder than he believed was possible. It’s a huge help having an experienced driver luring your outside your comfort zone.

Logging that first milestone lap gave him the confidence to try the Speed SF Challenge the next weekend at Thunderhill’s five-mile configuration. He did his homework and studied several record laps, focusing on curb usage. With Gary Yeung giving him some basic feedback the day of, Thomas saw his lap times fall by as much as four seconds. In the end, he was able to clinch third place in S2 — just half a second behind Kevin Schweigert in his BMW M2.

That success turned Thomas into a sponge. His subsequent lapping days have been spent studying data and having the experienced drivers like Joe McGuigan critiquing his onboard videos. “Joe’s been a huge help; giving me pointers on which gears to use so I can put the power down more easily.” The result of this traction-conscious approach to driving is evident in the footage below:

He’s also benefited from picking a short list of prime parts. In fact, he’s never bent his Titan 7 wheels or broken any suspension parts, despite hammering curbs and dropping wheels regularly. Maybe it has something to do with emphasizing robustness with this build—a tip he picked up from his mentor, Gary Yeung.

‘I’ve learned a decade’s worth of motorsports knowledge in the last two years. Everyone’s been so supportive, and I owe my progress to all of them. They’ve pushed me to improve as a driver and a builder—especially Gary. Watching him work inspired me to raise my game, and I think it shows. My Corvette’s overbuilt, so I can push it all day. Like Mango, my Corvette is a workhorse that’s made it possible to attend almost every Speed SF event in the last two years. All I do now is change the fluids and try to find out where I can go faster.”
