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. 

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.

Pauline’s Challenger: Part Car, Part Canvas

To earn her racing spurs, Pauline Yruretagoyena’s picked a car which mightn’t have had the greatest following among the track day crowd, but it pulled at her heartstrings the hardest. More than just emotive, her 2019 Challenger R/T was reassuring, stable, and safe, and having a 5.7-liter engine mated to an eight-speed automatic allowed Pauline to leave a little on the table and still get her kicks.

Which isn’t to say she was taking it easy. Pauline pushed herself to explore new and uncomfortable situations in which Her driving talent would be shaped for the better. For instance, her willingness to drive in wet conditions helped teach her how to drive smoothly and precisely. After she saw the benefit some of the arduous challenges offered her, she decided to take a two-day high performance course at the Radford Racing School. Among other skills, this school taught her how to trail-brake well enough to get the big Challenger pointed in the intended direction sooner.

Her ardent supporter and personal mechanic Adrian then equipped her Challenger with wider 285-section front tires, BMR linear springs, an Eibach hollow swaybar, Mopar strut bars, and the Brembos from a higher trim Challenger. These all contributed to an encouraging surefootedness and crisper responses when pushing the car harder than before. Most importantly, they’d get the big barge pointed in the right direction earlier so she could take full advantage of its impressive powerplant.

And as much fun as she had with the R/T, when 2022 rolled around, she had to consider the circumstances that made getting a perfect upgrade possible. Dodge had then announced the Last Call for the Challengers with their legendary HEMI engine. They also brought back the Plum Crazy paint option for the 2023 model year that had been discontinued in 2019. After two years of competing with the old automatic car, she was hankering for a manual.

So she ordered a 2023 Dodge Challenger Scatpack R/T Widebody with the T/A package — meant to commemorate Dodge’s success in Trans Am. It came with a wider footprint than her previous car, the most powerful normally-aspirated V8 in the Dodge lineup, adaptive Bilstein dampers, a limited-slip differential, and a manual transmission.

“I knew it was for me when I saw the color and the fender flares in person,” she gushed.

There’s not much more the car needs from factory. Underneath the blistered fenders is a square set of 305-section tires, and the 6.4-liter up front comes with 485 horsepower and none of the heat issues the supercharged Hellcat endures on the track. As it was already suited for track work — far better than any other variant of the Challenger — Pauline didn’t have to consider a list of modifications to make it track worthy. Instead, she could spend the first four months of ownership getting her head around its one novel (for her) features: a TR6060 six-speed transmission.

Long before she took this new car to the track, she put nearly 1,500 miles on the car — many of which in an empty parking lot or a deserted graveyard road. Without having to worry about traffic, she could practice the basics of driving a three-pedal car, as well as some of the track day techniques like heel-toe.

There was no way she could sensibly practice downshifting under heavy braking while on the street, but her time spent studying videos online helped prepare her for a Speed SF event at Laguna last June.

There, Joe McGuigan helped her fine-tune her blipping and clutch release so that she could coordinate her gearchanges crisply and keep the motor in the right rev range. Though the challenge was made somewhat more challenging by the T/A’s straightline performance — seriously greater than her R/T’s, with Hawk DTC-60s at all four corners, she never felt the new car lacked any braking performance during her first day. After a few sessions of bucking on the brakes and dragging the motor, it all began to click. By the end of the third session, she set a lap time ten seconds better than she ever had with the old car. Considering the T/A still needs a new alignment and a few other additions to make it truly track-oriented, that’s a remarkable improvement.

Her clean, level-headed driving impressed Joe enough to recommend she try the Speed SF Challenge series. “He insisted I join, but I’m still waiting to feel comfortable in the car before I begin competing with the guys here. They’re all too fast!” she admitted.

Perhaps she undersells herself, but maybe she’s just being prudent. Either way, it won’t be long before her lap times convince her she’s ready. In the leadup to the her moment of unshakable confidence, she plans to widen the footprint with a set of Apex VS5-RS wheels wrapped in 305-section Nankang AR-1s, protect her paint with a full PPF, and make a few aero additions.

Given her studious approach, she’ll be on top of her new T/A in short order. Not that she needs to, since, for Pauline, it’s always been about enjoying all the various experiences a sentimentally motivating machine can offer: customizing its appearance, learning its different features, a finding time to savor the time spent cruising at moderate speeds in scenic settings. Spyro, as she’s named the car after her favorite video game character, is less a tool than it is a personal statement and a means of finding satisfaction on a daily basis.

Between her insistence on seat time over primo parts, as well as the importance she places on feeling something sentimental for her vehicle, she could teach a new generation of spirited drivers that a successful track day has little to do with having the fastest car in the paddock.

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.

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.

Jacek's M3: In Good Hands

Indoor karting lay the foundation, then construction gigs throughout college gave Jacek Kozubek the chance to scrape enough money together to buy himself a two-stroke kart. He flipped a few cars on the side, too. It seemed there was never enough money to fund his new habit back then.

Frustrated though he might’ve been, he kept going with his entrepreneurial pursuits, and these put him in touch with more experienced racers who could make his transition into racing full-sized cars even easier.

Once out of school and making a little more, he started scanning his surroundings for the right track car. It was R-Crew Inc. who helped guide Jacek through this often frustrating process, and after an introductory period with a healthy DC2 Integra, Jacek followed R-Crew’s advice and picked up two of the more popular platforms in today’s track scene.

After the end of this trial period, he decided he preferred his E46 M3 to his S2000. “The S was great, but I felt a little disappointed with the straightline performance. It was better than the BMW stock-for-stock, but when I got to drive Don’s M3, I could see how good an M3 could be with the right modifications.”

Wisely for a man buried in work and family obligations, Jacek handed the car over to R-Crew for modification and maintenance. The first order of business was the typical set of wheels, brakes, and coilovers, though he saw no sense in half-assing it. Fancy footwork it would be, and after adding AP Racing 5000R brakes, JRZ 11-series coilovers, and a set of 18x10” Volk TE37s, the M3 was no longer the plush and porky thing it was in stock trim. It was now a riveting street-track car, but far from perfect.

There was still some sponginess to the car, as well as a notable lack of traction in hairpins. R-Crew replaced the poly bushings with heim joints, then fitted a 1.5-way OS Giken diff to minimize inner tire fire. The resulting surefootedness provided the platform upon which Jacek could add some aero grip; a Bimmerworld splitter and full-carbon wing only helped the car—there were no slow-speed shortcomings from the wings.

Since Jacek handed the car to R-Crew for transportation to and from the track, he didn’t see any reason for keeping the car even remotely streetable—it would be a full-on track build. Out went the interior and in went a Tony Colicchio cage. Additional weight shedders included a set of lexan panels to replace the rear quarter glass, Bimmerworld fiberglass doors, and R-Crew’s full exhaust. After the dieting measures, the M3 weighed in at a respectable 2,850 pounds with driver.

That full exhaust was the only modification made to the motor, and that simple recipe made it into a dependable lump. The S54 sometimes gets a bad rap, but with the right sort of maintenance, it’s a workhorse—Jacek’s record is testament to that.

In four years, he’s run roughly thirty-five faultless track days with this particular engine. These aren’t standard track days either; Jacek typically runs multiple run groups on the same day. Sometimes, he’ll drive two consecutive twenty-minute sessions, and after missing the first few laps of the third session to fill up at the pump, he’ll finish out was is nearly a sixty-minute sprint.

With all the big boxes ticked, there’s not much more that the car needs. For Jacek, a driver who prioritizes seat time, he’s absolutely fine with that. However, the car could go from welterweight to lightweight with the two big jobs on the horizon. After fitting a carbon dash, the guys at R-Crew plan to pull the entire wiring harness and install an AiM PDM32: a solid state power distribution module that allows them to pull the fusebox and all relays. With some luck, these two mods might shed another two-hundred pounds.

Hoosier A7s have been his choice for a long time now.

Over the last fifteen years, from scrounging cents to run karts to spending big dollars at the track, Jacek’s enjoyed good luck with his hobby. When money was tight, he focused on getting the most track time in the way that was feasible: through karting. Now, after making some money, he’s learned to spend it wisely. With all the newfound freedom it’s brought, he’s come to value his time more, and rather than spend it wrenching, he’ll happily hire those who do this stuff better than any hobbyist would.

By leaving the car to R-Crew, he’s been able to ensure his time at the track is spent as efficiently as possible. The car runs without hiccup, it’s set up to suit his driving preferences, and if ever he’s got a question about a change he could make, he has an experienced crew to consult. He’s gone from frugal to experience-focused. If an ambitious driver has the means to leave maintenance and transportation to the professionals, why not? It’s always better to be in the best hands possible.

The money’s been spent, and now all that has to be done is drive, really—drive it into the ground. “I use my iPhones until they’re so cracked I have to replace ‘em, and I’ll drive this car until I put it into a wall.”

It’s amazing how he’s been on the money the whole time.

Alex's RUSH SR: Turning The Page

Alex Chang’s foray to North American track days with a track-prepped Z4M was fun, but it’s odd how, now, after trying a single-purpose open-topped racing car, he’s thinking about parting ways with it.

Alex’s upbringing in Brazil gave him a chance to get some karting miles underneath him before purchasing a Civic Si and running a few pricey lapping days at Sao Paulo’s Interlagos. That was a bit of a tease as the hobby was then out of reach financially, but his karting experience and the greater speeds of the bigger tracks had left an indelible mark on his young mind.

By the time he moved to Los Angeles, Alex had made a little more dough and started looking for another way to get his speed fix. Urged along by Sam Kim and Ed Kim, he decided to try the North American style of lapping days at one third the cost of the Brazilian alternative.

Inspired by his BMW-loving brethren, Alex bought an E92 M, but he couldn’t connect with it in the way he hoped he would. The desire for an unadulterated driving experience pushed Alex to purchase another front-engine production car from the same family, albeit one both smaller and lighter. With some luck, it would feel a little more like an extension of himself.

He didn’t hesitate to pick up his Z4M Coupe, which had plenty of promise. With the venerable S54 and a wheelbase ten inches shorter than the E92’s, the potential for an involving on-track experience was there, and for the first year, the rapid breakaway kept him entertained. “You must have quick hands to drive this car!”

And so the foundation was set. There wasn’t much hope for outright lap records in this car, but it scratched some of the itch and, if he could look past the steep price of aftermarket parts, was a solid car with moderate-to-low running costs.

Bigger brakes, tires, and eventually power mods helped generate some extra excitement on his monthly outings at the track, but the addition of aero had the opposite effect—the Z4 became too planted.

Without any nervousness to keep him on the edge of his seat, Alex decided to shelve the trackday hobby for a while; he’d just become a father and had more pressing concerns than getting his adrenaline fix. Getting to wake up in the middle of the night to a baby’s cries did that just fine.

But it’s hard to put the helmet down forever, and after his brief sabbatical, Alex sought out something else to give him a purer thrill. He toyed with the idea of a Radical SR8, but its reliability issues scared him off. Still, a short test in one helped him recognize that an open-top/single-seater sports racer was what truly appealed to him. After stumbling upon a Facebook advertisement for a new open-top car called a RUSH SR, he acted without much deliberation and put in an order with Jeff Schneider from Fresno Powersport.

The 1,100-pound sports racer has a tube frame construction, a GSX-1000 motor that revs to 11,800 rpm, easily removable bodywork, and a moderate amount of aerodynamic grip.

After stepping into the RUSH, Alex found himself in a wildly different environment. The car was bare, raw, and responsive in a way anything over 3,000 pounds can never be. Its attitude was so easy to adjust, which pushed him to focus on altering his driving inputs much more than he ever had with the BMWs. “I might’ve been relying on modifications to go faster before, but, to be fair, that might’ve been because I never really had another similarly-modified Z4 to measure myself against—and so my driving has never received as much attention as it does now.”

The driving experience was undeniably pure, and the operational costs more than justified the entry price. A set of Nankang AR-1s run him $700 a set, and they last him eight-ten track days; they begin to fall off after around twenty heat cycles. A set of brake pads and rotors run him $30 and $70, respectively. Reduced operational expenses and a sense of support from the surrounding community gave him a way to evolve quickly.

Not many vehicles make a Z4 look enormous.

More than the driving experience, it was the community of RUSH enthusiasts on the West Coast that made him feel he’d made the right step forward.

The tight-knit group is growing fast, though still relatively small. Nevertheless, their competitive nature and the mechanical parity of their cars has pushed them all to develop quite quickly as drivers. “I actually was never considering wheel-to-wheel, but the other guys were getting their competition licenses and encouraged me to join them. It’s like having a second family at the track.”

With the cars all being equal, it all comes down to who drives the best that day and regardless of who wins, they all celebrate. “If it wasn’t for the RUSH SR and its community, I would’ve quit”

They’re all glad Alex didn’t stuck with it. He’s just returned from events at Sonoma and Laguna Seca this last October, where out of a field of twenty-four RUSH cars from California, Texas, and Canada, he was a top-five contender both weekends. With a little more seat time and a little help from his new RUSH family, Alex might be a front-runner in the upcoming season.

What’s certain is that he won’t regret his decision to follow his gut.

Blake's M4: Friendly Firepower

Lead photo credit: @danielbooty

He could look past one letting go, but when the second EJ motor blew, Blake Titus’ honeymoon phase with his WRX officially ended. Though there was an opportunity to rebuild for the third time, Blake sensed a better platform might help him make an easier transition from autocrossing into track days. He was half-right. 

The Subaru’s successor, an S52-swapped E30, held some promise, and for a while, it seemed like he’d found a way to get his jollies with half the headaches. That wasn’t to last.

As it turned out, the S52’s head had cracked somewhere on the way to his first track day at Thunderhill West. After pulling his oil pan’s plug, a milkshake poured out, and Blake considered throwing in his helmet. 

Thankfully, there was another car sitting in Blake’s garage. His F82 M4 was far from track-ready, and the predicted running costs made him wince, but it was operational and still covered under warranty.

His first outing at Laguna was successful; a 1:42.10 is an encouraging time for a heavyset grand tourer with more torque than traction. Sure, it floundered around on stock springs, but that time in an intermediate’s hands proved beyond a doubt that the F82 platform had potential. He knew it wouldn’t be easy on his wallet, but out-of-the-box performance like that can make people do silly things.

Curious where he could start tweaking the car to find some more cornering speed, he got underneath it and studied the intricately arranged layers of structural stiffeners meant to help the big BMW belie its weight.

“You just have to look around and marvel at how much structural bracing there is. After a while, you start to ask yourself, ‘How could I improve upon this?’”

Thankfully, not much is needed to get this car ready for the racetrack. The first round of basic bolt-ons consisted of a staggered set of Apex EC7s wrapped in Toyo R888Rs, GLoc R18 and R10 pads, Castrol SRF fluid, and a set of Girodisc two-pieces—the factory rotors would warp after a few track days.

That simple setup served him well for the first year of tracking the car, but after he’d gotten properly acquainted with the M4, he sensed the weight wasn’t being managed as well as it should be. 

To hasten weight transfer and provide a little more body control, Blake picked a set of Swift Spec R springs measuring 5K and 13K front and rear, respectively. These were a grand compromise; they were chosen so that he could retain some semblance of comfort on his drives to and from the track. Mainly, they allowed him to keep using the factory EDC dampers.

“I’ve kept it full weight for now. I thinks it’s pretty easy to turn a nice dual-duty car into an uncomfortable POS,” Blake admitted. 

The rubber began to feel like the limiting factor after some time, so Blake bought a new set of tires that promised more consistency. The Nankang AR-1s delivered in that respect, and they helped him chop two seconds off most of his best times. 

They would fade fast, though no faster than any other tire he’d tried. Its heft was undeniable and, unfortunately, virtually unmovable. Most of the strippable weight sits around the rear axle, which shouldn’t be removed. Even in stock trim, the M4 needs more weight over the driven wheels; it always struggles to administer the S55’s power without wheelspin. 

In the name of improving traction, he decided to try to force the rear into the pavement with Bimmerworld’s GTMore wing. It made a considerable difference—he chopped his time at Buttonwillow 13CW by four seconds the first time out. However, the front hadn’t been balanced aerodynamically and the resulting understeer made it even easier to fry the fronts. Bimmerworld’s rep recommended he try a track-oriented set of shocks, so Blake bought a set of MCS two-ways and turned a few knobs.

Few things have helped settle the rear like Bimmerworld’s dry carbon GTMore wing.

He might not’ve known precisely what he was doing, but he was relieved to see the rep had Blake’s best interests in mind. The resulting compliance made a world of difference—particularly at the bumpier tracks he frequented. At Buttonwillow 13CW, Blake could drop his best time by nearly three seconds—a 1:55.8. Quite an improvement from a set of shocks adjusted and an educated guess.

He figured that then would be as good as any time to throw a front splitter into the mix, so he tried cutting his own Alumalite piece and bolting it to his front, but it folded at the end of Thunderhill’s front straight. The replacement, Turner Motorsports’ MC2P splitter proved more resilient and effective, though it still cannot match the downforce generated at the hinteraxel. To find an agreeable balance, Blake had to reduce the wing’s angle of attack.

By this stage, Blake was pushing the car hard enough to test the powertrain’s thermal resilience. After one frustrating leak from the charge air cooler, he replaced the factory item with one of CSF’s, and swapped the standard heat exchanger with a Koyo unit. Since then, it hasn’t been fazed by August heat.

A square set of Yokohama A055 slicks mounted on narrower APEX VS5-RS wheels gave him the grip and neutrality he’d been seeking for some time, and with the elements cooperating, Blake went back to Buttonwillow and logged a 1:54.3—his best yet.

Blake’s still searching for a 52, but he feels that the M4 needs to diet or get its footwork finely tuned by a master before that’s possible. As mentioned earlier, pulling weight isn’t his idea of a good time, so he’s decided instead to buy the every one of Turner’s adjustable suspension arms as well as their differential bushings for perfected body control. If all goes to plan, he won’t have as much difficulty putting down the power—which he’s recently increased with a Bootmode BM3 CS tune. As much.

While the F82 M4 doesn’t change direction like a true sports car can, it compensates with unbelievable power—enough to spin at seventy in a straight line. Where it’s at its best is in the longer, faster corners; the long wheelbase and accompanying stability make it easier to trust in these bends. At this point, it’ll just take a little bit of tweaking to make it a nimble thing in the sections where traction and rotation take precedence.

If Blake’s experiences have taught him anything at this point, it’s that “the torque is always trying to kill you, so you have to be very quick with your hands and be confident in your skills; you have to drive with all the nannies off. MDM will kill your lap times and too many people rely on these systems. Then the first time they turn the traction control off they send the car to Copart.

The F82 is an amazing platform that still lacks in some of the aftermarket support that have made the E92, E46, and E36 such appealing track cars. Still, the potential is there to make the F82 a real contender once the rest of the world catch on. I can’t wait to see what other companies offer in the future to keep improving on the platform.” 

Speed SF Challenge Laguna Seca: New Surface, New Records

Ideal weather and a massive turnout of thirty competitors at the last round of the Speed SF Challenge guaranteed some action. Sure enough, we saw new records in several categories. Though some of the newfound speed was due to the recent repave, our Challenge drivers were in stellar form that weekend, and their onboards prove that.

In S1, Steve Melson and his Audi R8 broke the S1 record that had been standing for five years, set back in 2018 by Andrie Hartanto in a C6 Z06. Steve took advantage of the stellar weather and logged a 1:34.081 — a new record that any driver should be proud of—in a car that looks nearly stock. Such is the performance of the second-generation R8.

In S2, Kai Anderson reset Peter Hsu’s Chevy Corvette record by seven tenths. Anderson ran a 1:34.8 to Hsu’s 1:35.7, but not before suffering through a few frustrating sessions. By the end of the day, he cooled his jets long enough to find a gap and avoid slower cars. “My main challenge was recovering from a poor qualifying. There was a good turnout for this event which was great, but it meant the morning sessions were a little crowded, so I ended up only qualifying 7th fastest overall. I recovered to 4th fastest overall in the Challenge session, so mission accomplished, but my fastest lap didn't come until lap 5 because I kept having to abort laps due to catching traffic.

I didn't really have any specific goals for the weekend; mostly just evaluating what is still a relatively new car to me on a newly resurfaced racetrack. Overall, I was impressed with both. I think the changes to Laguna really inspire confidence to push for that optimal lap without creating a different line that requires total abuse of track limits.

The Camaro is perfect for Laguna, with prodigious power, cooling, and brakes to match. There is definitely still some laptime to come from this pair. Crossing my fingers December is dry!”

In S3, Spencer Kimball put in a serious effort to try and beat Kevin Schweigert’s S3 record of 1:36.0.

“I went into this event with some reservations knowing that my M3, with limited torque, was not at its best on Laguna’s straights. Laguna is also the one local track that I drive the least, but I made sure to try and get some practice in before the Challenge weekend. I lucked out and a friend lent me his pass for an event the weekend before, where I ran a low 1:37 after a year-long Laguna hiatus. I looked over my data and saw that a mid-35.xx would be possible, but I went into the Challenge event with the goal of breaking into the 36s. 

I knew that I had my work cut out for me as my main competition, Legend Brandenburg in his A90 Supra, benefits from ~200 more ft/lbs more than my E92 has. Luckily I was able to run a mid 1:36 during sessions 1 and 2, which put giving me a good spot for the challenge session. I studied my data to figure out where I needed to commit, and it was clear that the faster corners were where I could push harder to find somet time. I ended up running a 1:36.5 in the Challenge by carrying more speed through T5, T6, and T8, which was enough to make me the fastest in S3.”

In the end, Kimball was just 1/2s off of Schweigert’s lap, which Schweigert set in a car weighing 500 pounds less with comparable power levels. Not too shabby.

Gary Wong still has a little bit of work to do in the Supra to find the second between him and Dave Colbert’s 1:31.5 Group X record. The infamous purple Supra had its engine tweaked slightly to reduce power cuts, but heat is still an issue which Wong has to deal with. Thankfully, the team has a solution—though they won’t be able to use it until the next weekend.

“It was a fun weekend. I mainly wanted to sample the new track surface and see where I could push more than before. Because of how bad the stupid bump at T1 is, I wasn’t able to hit our sub-30 target times, although that had something to do with to traffic and some electrical gremlins. Because of some overheating issues, we had to lower the power level to complete the full lap. Thankfully, we know the issues and the solutions and we’ll come back stronger.”

Gunning for the S4 record, Nate Hackman’s put in an incredible 1:39.7, less than one-tenth off of Sean Yepez’s record, in what appears to be a very mildly modified car without any aerodynamic goodies. The primo parts are under the skin, though: his Ohlins TTX coilovers help his S2000 handle better than most. A last-minute setup change reduced some of the oversteer in the car, so Hackman could commit to the faster corners easily.

“Up until that weekend, I had only mustered high 41s at Laguna. With the repave running faster and a few changes to the car I figured I'd run a second or two faster, but tried not to overthink it with goals and just go have fun. Luckily, I was able to cook off a number of 39s with some definite room for improvement. I was still a tenth off Sean's pre-repave lap record which was a little disappointing, but I knew he'd come back and crush any record I set, and was still very happy to crack into the 39s with no aero and take home a win with an underbuilt car.”

In S5, Tony Rodriguez’s 1:45.2 record seems untouchable. Maybe we need another all-out MR2 to chase Rodriguez’s old S2000 down. In the meantime, we’ll have to tip our hats to our talented drivers taking advantage of the new pavement and pushing themselves hard enough to keep all the Speed SF Challenge competitors on their toes. When times continue to tumble like they have been, none of the Challenge competitors can coast, boast, or rest on their laurels.

Steven's McLaren 675LT: Hardly Fair Anymore

Four seconds faster. A whole four seconds faster after a couple sessions. That’s the amount of time Steven Melson cut off his previous best, set in a V10-powered R8, just after getting acquainted with his new car.

It was his coach who had been gushing about the McLarens he and his clients had been driving in recent months. Steven, though he hadn’t come close to purchasing a car of that caliber before, was beginning to wonder whether he should add one to his collection.

It took him over a year of maybes, mishaps, and genuine frustration—culminating in a trip to Texas to test one at COTA to get a feel before pulling the trigger. The car he was supposed to test, a Papaya Orange 675LT, was crashed by its owner just minutes before Steven was supposed to take it for a spin. Some would’ve given up on the idea then, but Steven’s coach had convinced him that one of these cars was worth holding out for.

A week later, the listing for another 675LT, this one finished in Chicane Grey, popped up in his inbox courtesy of a supportive friend. It didn’t take long before Steven made a decision.

At just 2,950 pounds, the 675LT is nearly a half-ton lighter than his Mercedes AMG GT and four hundred pounds lighter than his Audi R8 V10. Compared to the Audi, which now wears a set of Penske racing shocks, the McLaren is much more alert. “The weight difference is obvious,” Steven began.

Thanks to the carbon tub and the active suspension, the grip and lateral support is much better than the Audi’s, if maybe coming at the cost of a slightly duller feel. To improve matters, the McLaren’s quicker steering and sharper front end, as well as a more stable rear at higher speeds bolster Steven’s confidence and encourage him to push.

And its urgency is only part of its appeal. The power is savage, relentless, and genuinely shocking—I remember the first time I drove one, and I had to let out a few expletives after the boost hit. It can spin the wheels easily in third and sometimes fourth, yet the power is somehow controllable.

There aren’t many cars which will out-accelerate this surprisingly exploitable supercar.

Despite making the sort of power that few track cars can, the delivery is fairly linear and very controllable. “I don’t get the feeling of ‘Oh God, now the boost is on!’ Really, it’s not that intimidating,” he professed.

What does surprise him is the way which the McLaren decelerates. “The stopping power is amazing—so far beyond the Audi or the Mercedes. I’d usually overstep the mark in those two cars, but I haven’t found the limit yet in this. Every time I try to push the braking point later than what feels comfortable, it just stops,” he laughed.

And despite the systems providing him some form of safety net, the McLaren is exacting—so much so that he’s started augmenting a few mistakes the plusher, less demanding Mercedes let him get away with. “My coach told me to try and get back to the throttle earlier and earlier; it just takes it. In fact, it’s helped me work on my bad habit of coasting mid-corner,” he admitted. To get the rear settled early and softly has opened his eyes up to the dynamic differences between a hard-edged car like this and his relatively plush German machines he’d gotten used to.

To get a better sense of how these three differed, he took them all to the McLaren’s inaugural track day at the Thunderhill Bypass last December. After one day of familiarizing himself with the new car, Steven put in a searing lap of 1:51.5—four seconds faster than the best he’d managed in the Audi. That’s with an indicated 154 miles an hour on the front straight and a lot of mud on several parts of the track. If that’s not an indication of accessible speed, I’m not sure what is.

Being as quick as it is, he hasn’t really considered toying with the suspension much. He has, however, decided to extract a little more power from the M838 motor with a set of catless competition downpipes from Soul Performance and a tune from M-Engineering. On 100-octane fuel, these goodies should make another hundred wheel horsepower—another hundred wheel in a car which runs 10.3 in the quarter bone stock. “It’s probably all I’m gonna do for a while—I just wanna learn to drive it better, have fun, and beat some X records,” he admitted.

Sounds like a reasonable plan of action.

Rich Bonem's BRZ-Camaro Dilemma: Speed Costs Money

Years of construction work meant his hands weren’t what they used to be, but that only meant that Rich Bonem had to find a new outlet. That and a few objections from his loved ones was why he switched from lapping crotch rockets to time trials in Subaru BRZ which, even in stock trim, was already a fantastic driver’s car. Light, agile, and encouraging, his 2017 BRZ Performance Pack served him well that first year, during which he squeezed in twenty track days—and all he did to ensure the car ran well was add a Mishimoto oil cooler.

The modifications came the following year. With a set of Enkei RPF1s wrapped in 255-section Bridgestone RE-71s, the BRZ was surprisingly capable of near-factory footwork. To make the most of that improved stance, he used SPC’s rear control arms and their toe arms to dial in a track-specific alignment. With 3 and 2.5 degrees of negative camber front and rear, respectively, the car could be leaned comfortably, generate the needed mid-corner stick, and oversteer predictably—just what the underpowered BRZ needs for fast times.

Although power wasn’t its forte, the BRZ was able to be livened up some. Rich tried what he could to squeeze a little more from the FA20 with UEL headers, a JDL high-flow cat, an Invidia N2 exhaust, as well as an OpenFlash Tune. It wasn’t groundbreaking horsepower, but 180 horsepower at the wheels in a 2,700-pound car qualifies it as quick.

With a set of Verus brake ducts topping off the short list of mods, Rich had himself a competitive car he could take to 86 Challenge. “What’s really cool about the 86 Challenge is the fact you can take a completely stock car and compete. Every event has had a great turn out, and when you’re ready to add some more upgrades, there’s a group for you, no matter how modifed your car is,” Rich says.

This car and this competition provided Rich with the realization it sometimes takes eager track rats years to learn. “When you’re competitive in motorsports, seat time is the best upgrade. In just one year, I went from being a complete noob to being one of the fastest guys at the track, and this was due to regular lapping days and the way I gained confidence so quickly. Every lap you push a little harder, brake a little deeper, focus on more advanced techniques, and study the features on the track that are so hard to notice when you’re new and uncomfortable.”

Still, that challenge could only last so long. Eventually, he felt like he hit a wall. No matter what he tried, he couldn’t improve upon his personal bests.

Looking into the cost of getting more power from the temperamental FA20 seemed silly; a little research into Kevin Schweigert’s experience with his supercharged BRZ wasn’t encouraging; things started to break things once past the 350 horsepower-mark. For that reason, Rich decided to leave the underpowered lightweight behind and move onto a new platform.

In addition to brakes the size of medium pizzas and a motor over three times the size of the Subaru’s, the Camaro SS 1LE represented a new challenge to Rich. It was bigger and harder on consumables, but unlike the Subaru, it had a robustness and, crucially, a warranty which made tracking it relatively easy on his conscience.

Not surprisingly, Rich was staggered with the car. The braking performance was stunning—seeing a measured 1.3 G in the heavier braking zones was a big surprise considering the additional half-ton of weight. “I felt my soul leaving my body,” he reflected.

The interior offered plenty of space, the gearbox was sweet, and the general reliability was impressive, too. Therefore, the ease of transition was more than just calming—it was inspiring. “The Camaro really made me feel like a superhero,” he added.

True, some things needed improvement—he added an APR GT300 rear wing and some adjustable rear toe links, then dialed in a little more camber all around. Other than that, it was left stock, because it was more than he could fully exploit at the time of purchase.

If it had any flaws in its driving dynamics, it’s that it wasn’t’ not the chuckable thing that the BRZ was. Still, it compensated for the added size with real stability and, obviously, a lot more motor. He increased the front tire width to match the rear 305s, but in its current configuration, the 3,800-pound bruiser still lacks that urgency that he loved so much in his old car.

For Rich, the dependable, reassuring balance, great high-speed manners, and stress-free lapping were the outstanding traits—outstanding enough to forget about its few flaws.

Good manners and an extremely stable platform gave Rich the encouragement needed to push his expensive track toy.

Except one. That ease of tracking and the obvious challenge kept him from ever feeling stagnant or frustrated, but he couldn’t help noticing the damage done to his bank account. Between track day insurance, gas, tires, and brakes, Rich found he was spending nearly twice as much every weekend than he had with the Subaru. Speed and power were fun, but like Kevin Schweigert realized, they’re not everything.

Brake pads lasted only four lapping days, and the tires two—the massive weight wearing out the shoulders extremely quickly. Not surprisingly, he’d only managed half the number of track days in the Camaro over eighteen months than he had with the Subaru in one year.

For Rich, the Camaro is the simple solution that so many track guys are looking for. “It’s a tried-and-true platform that will work, but I find myself already feeling like I want more. I can make it faster, but to upgrade an already expensive car is just crazy. Now, I believe I’d rather start over with a stock BRZ and upgrade slowly to appreciate the differences each upgrade makes. Maybe a K24 engine swap in the future?”

This journey has taught him of all that which is really important in a track car, as well as the cost restrictions and practical limitations that the starry-eyed builder never really understands until they’ve sunk half their savings into a creation. To win requires practice, and to have fun requires a constant challenge and regular advancement towards that goal on the horizon. How does one balance that? That’s up to the driver and their tastes, finances, and abilities.

Sean's S2000: Happy To Take The Abuse

Sean got his racing introduction through Spec Miatas. From 2006 to 2009, he spent his time on racing these little cars and learning the finer points of how to keep minimum speeds up. Close competition and no power acquainted him with the challenges of rolling entry speed and minimizing scrub—the two best ways to find speed in an MX-5. Though true with all cars, finding real speed in the Mazda depends entirely on those two. Whatever mark was left on him through those years of competition served him later in life when he sought the answer to a question that’s plagued many drivers: what really matters in a sports car?

After graduating in 2010, his new job started taking up more of his time. No longer would his schedule allow for the hectic race weekends, so he sought his kicks in a more cost-effective, flexible fashion: lapping days.

However, he found that his Miata was hopelessly outgunned by the V8-powered cars at track days. Even mid-tier Camaros using two-thirds of the track would walk away from him, so he wanted sometime more powerful to feel closer to the front of the pack. The answer was not a muscle car, thankfully, but another lightweight with more power and a better weight distribution.

His Lotus Exige was fast, but it was beset with problems. Setting one up took a lot of innovation as there were very few local HPDE drivers driving them back then. It also had a habit of heat soaking after a few laps, so he was pressed for time to put in a flyer. Plus, he was constantly sweating the inevitable repair bills. “At the end of the day, I realized I was only getting about twenty laps in on any given track day—tops. I couldn’t shake this feeling that I was working too hard for not enough payoff.”

What Really Matters

Sean’s foray into lapping days in an exotic was a little underwhelming, so he took what some may consider to be a step backwards and purchased his friend Tom’s 2005 S2000. The car was largely unmodified, with just a roll bar installed by SpeedSF veteran Dan Avon.

Rather than seeing this as a demotion, however, Sean saw it as a step in the right direction. The S2000 offered him some of that Miata reliability mixed with much more speed. Most importantly, it offered a better balance of time invested and emotional payoff.

“The car had to offer me a couple things. First, I wanted to focus only on my driving. Also, I wanted to have a car that had been well developed already, mainly so I could save time setting it up, but also so I could gauge my performance against other drivers with similar equipment.”

There was another realization he had after moving on from the Lotus to the Honda. The more mechanically sympathetic approach needed in a fragile, powerful car kept him from feeling truly alive. He preferred something he could push harder and harder until he found the limit—something not restrained by too much power, heat soak, or any other technical setbacks. “There’s a strong correlation between my happiness and the amount of time spent at full throttle,” he declared.

Naturally, the simpler S2000, all too happy to take the abuse, gave him an opportunity for unrestrained, aggressive driving without him feeling any need to baby the equipment.

Build Ethos

Inspired by the quick local S2000s built by Seigo and the Garys (Yeung & Wong), he got to work sorting his car out. The objectives were to stick to the proven parts, retain all the factory body panels and all of the interior pieces, and avoid JDM parts. The last aim mainly for price reasons.

The parts list is short, but a car that is so strong from the start doesn’t need much other than a committed driver.

Unmodified 183,000 mile AP2 engine

Ohlins DFV dampers (a little on the soft side)

Karcepts sway bars F/R

Racebred 3” splitter

Factory CR lip

AJ Hartman swan-neck wing

Stoptech C43/C42 brakes F/R w/ SR33 pads

Recaro SPG bucket seats

Sabelt six-point harnesses

Titan 7 T-R10 wheels

Maxxis RC-1 R2 tires

Despite trying hard to avoid the pricey Japanese parts, a Mugen steering wheel founds its way into his life and the price was too good to pass. Once the rule had been broken, he had less of a problem adding the renowned OS Giken limited slip differential. “I guess I failed with that aim,” he laughed.

A Motivational Sparring Partner

To get the most from the car, Sean had to set it up so that he could steadily increase his forcefulness behind the wheel. Therefore, it had to be confidence inspiring and somewhat stable—it had to encourage him to push.

Sean describes the Honda as neutral bordering on pushy. The mild downforce encourages smooth inputs, and its intuitive brake balance makes it fairly easy to trail brake. Despite the grip, it’s still a 220-horsepower momentum car that needs to be driven in hard. In fact, throwing the car around a little and tempering any excessive aggression is the way to get the most from it.

Though this footage Sonoma demonstrates a safe sort of understeer in the first two laps, he is able to unlock a little more rotation simply by pushing harder towards the end of clip. After a 1:52 and a 1:53, he found a little more confidence needed to start asking more of the front and neutralizing the push with more curb usage and a lot more entry speed. Getting on top of the car and ramping up his steering rate resulted in him chopping two seconds off his previous time, resulting in a S4 class win and a new class record of 1:50.6.

“I can set the fastest time on the seventh or eighth lap in this car, so I have plenty of time to put together a lap methodically. It allows me to build up the pace and drive quickly without taking too many risks.”

After the car’s competitive debut this summer at Sonoma, Sean looks forward to continuing to learn from the great S2000 pilots in the area. Thanks to the S2000’s encouraging nature and the supportive, relaxed format of the Speed SF Challenge, he’ll be able continue whittling away his laps and learn everything that raising minimum speeds requires. If he’s given some more time to fine-tune the setup and carry all the cornering speed he learned in Spec Miata, he’ll find a couple more seconds—no doubt about it.
