Piers’ 240Z: From First Principles

Piers Hugh Smith recently took to mechanics through cafe racers — a consequence of lockdown boredom while living in London. Underneath his apartment complex, he began spending his spare hours rebuilding a classic motorcycle with the assistance of battery-powered lights and powertools as there were no outlets in the parking lot available to him.

“It was a 1970s Honda CB550 and it was a total wreck. I found it in a commercial waste site. I took the opportunity as a way to learn about rebuilding engines. It was just so simple and light — I could pick it up easily and install just about everything on my own.”

It also set the stage for his later projects by having a motor quite similar to a modern car’s. “Through some forum trawling and badgering a few friends over the phone, I learned my way around its carbureted inline-four and got it into a reasonable state. In fact, I commuted to work in London for about a year on it — a great bike for traffic that’s much smaller than modern bikes with similar displacement.”

Piers educated himself on the essentials of internal combustion and learn his way around an air-cooled four-stroke motor fairly quickly — thanks largely to his obsessive commitment to understanding the fundamentals, and the simple nature of a classic engine.

The smooth, swooping lines of a fastback had always spoken to him and his aesthetic tastes, which, after deciding to try his hand at restoring four-wheeled vehicles, made choosing the titular vehicle easy.

“I remember seeing a 240Z with the Pandem kit years ago while I was in school — it just blended the original curves of the car with something aggressive, but sympathetic to its basic shape. Plus, the fastback has great aftermarket support, so the combination of visual and practical appeal drove me towards modifying one myself.

This one came up for sale as an unfinished project. I was still in the UK at the time, where the car was, and the bodykit had been installed. The owner, a bodywork specialist, was asking a reasonable price since, mechanically speaking, it was a complete mess. The wiring was horrid, the interior was mostly MDF from the DIY store, and the mechanics were in poor state.

I got the car ambitiously; thinking it’d be a quick and easy finish, but it took a year and a half to get it sorted,” he admitted.

Over those eighteen months, he took to this car with the same fervor he had with his cafe racers. There was a plan, however — this was no flight of fancy.

Sympathetic Modernizing at a Reasonable Cost

“The whole idea was to learn how the chassis works and modernize it while preserving the original design intent and spending pragmatically on maximizing the driving experience. I thought about engine swapping the L24 with a BMW B58, but in the interest of preserving the soul of the car, I decided to keep the original engine and keep it carbureted, albeit with some modern updates to make it more usable.

It involved a full rebuild of the engine with partnership of Four Ways Engineering. It’s a basic performance setup with triple Weber DCOE40 carburetors, a bigger aluminum radiator, electric fans, a stainless straight-through exhaust, and a stainless intake. I haven’t yet dynoed it, but people with similar setups make around 180-190 to the wheels. I also converted it to electronic ignition and labored over the wiring by introducing common grounds and independent relays to ensure reliability, then I installed a newer and slightly taller diff from a later automatic 240SX to improve cruising manners and replace the tired original unit.”

The powerplant functional, Piers moved onto the chassis and its lengthy list of to-dos. “I wanted to modernize the handling, first by stiffening the body with some bracing, and then by welding BC BR coilovers to the original spindles and rear hubs.

“You buy a standard weld-in coilover that is the right size for the car, then you weld it to the original front spindle. It’s a generic fit,” he added.

Along with the new shocks, he turned to Silver Project, a Polish company specializing in 240Z suspension components builds, for their adjustable control arms and tension rods given the cost of securing US imported parts in the UK.

In keeping with the classic looks, he decided to updated the interior with some modest street buckets and an aluminum center console from Skillard, an Oregon-based aftermarket specialist, as well as a couple new powdercoated items to maintain a vintage period look inspired by aviation panels of the era.

The car has a weak point in its chassis stiffness; there is a lot to be gained by taking some load out of the original thin steel. Piers made up for this by introducing Apex Engineered triangulated strut braces in the front and rear.

Piers made the move across the Atlantic to San Francisco this January and brought his beloved Z with him, though it lagged behind by six months. Once he’d shipped and registered the car stateside, he made the next bolt move — to track the car. Last weekend’s event at Sonoma was a first for both him and the car he’d spent so long restoring.

A Day of Firsts

“While I didn’t build it for the track, I wanted it to be fun and capable. I drive it to work, to social events, and on backroads, too. I wanted versatility, mainly. That said, it was easy to see how testing the car on track could improve the product, ultimately.

The first day, it was flooding the cylinders with fuel at high revs on the main circuit, so I did a carb sync, changed the fuel ratio and jetting, and then went back out for the third session, where the car had much better power delivery and more predictable behavior. However, with the additional speed, I blew out the brake booster. In every other sense, the car performed really well considering its age as well as my experience as a builder.

Getting to run with my friends in modern cars demonstrated how these older cars are so much more analog; needing a thoughtful approach from the driver. I spent most of my time trying to preserve my momentum because there’s not much power, and it’s only available across a narrow powerband. I can’t just floor it; nothing happens. I need to listen to the car and plan ahead to make sure the car is ready for the next segment as it does not respond well to sudden changes in demand.

Now, through driving the car aggressively, I know that there’s an iterative list of improvements to make, particularly in the suspension and braking realm. It’s got too much dive, and it still has OEM brakes. There are cheap OEM disc-brake setups that bolt in fairly easily with some adapters. I might also add a five-speed box from the 240SX, another bolt-in item, then leave this car alone. It would sound good, stop well, and produce a reasonable amount of power. I think I would be very close to hitting my build objective of a stand out resto-mod which delivers a huge smile to the driver and passenger at a reasonable level of expense.

I’ve not yet spent much time on aero. Given the speed of the car, my goals for the build, and the marginal return of aero modifications, I do not think it offers the best bang for buck at this stage, but is undeniably important and something to consider later on.

The car’s sitting on much wider tires than standard: 9.5 in the front and 10.5 in the rear, and those might be slightly too wide for the power and stiffness. There need to be other changes in the package to support a footprint that size. This was a case of form getting in the way of function rather than sticking true to my original goal: for beauty in their harmony.

I can only say that I was really happy with the event. It was my first-ever track event. Having my friends there was great — to drive alongside them and to have their emotional support when I was spending time under the hood wondering why I didn’t just bring something fuel injected!”

This car, as beautiful and as expensive-looking as it is, was built primarily to teach Piers some of the intricacies of the chassis without costing him a fortune. “With this one, the obvious thing to do is to keep spending time on the setup; I made sure everything’s adjustable as there’s a lot to be learned through making the most of the car as it is before endless upgrades. As long as they worked well enough, I picked mid-tier parts to keep costs reasonable, too.

His second Z car, which he’s just started building, will be built to further his understanding of balancing performance, aesthetics, cost, and usability. “The chassis has already been seam welded and acid dipped with full length frame rails to make the thin monocoque frame a little bit stiffer. They’re not safe cars to begin with, and rather than engineer crumple zones, I will install a six-point cage with removable door braces. I believe that installing a cage is also the best way to stiffen the chassis. The next engine is still an original block, and the intention is to keep it naturally aspirated, but bored and stroked to get more modern levels of power.

There’s a company called Apex Engineering that does a very interesting double wishbone setup for the S30 Z cars in the front and rear. This would be an easy way to achieve more predictable suspension dynamics and a stiffer sub-frame style set up.

In the second car the goal is simple: to take a blank shell from first principles and combine it with what I learned in the first and use it to create a beautiful, analog, and enjoyable high performance sports car whilst staying true to the original design intent of the 240Z.

Now when I’m driving the car, I feel more confident given I understand the basics of how it works, and I think the education the car has given me has made me a more sympathetic driver. There remains a very long way to go, but understanding why the car behaves the way it does has really come from putting it together myself.

I spend most of my day behind a desk, so this is a great distraction from my normal day and focus on creating something immediately tangible — it has this incredibly different feeling to the rest of my time that it makes it easy to become hyper-meticulous. I keep lots of notes, so when I go down a rabbit hole on one dimension of the build, I don’t lose that learning when I actually come to implementation later on.

I remember my design teacher in high school giving me advice to sleep with a notebook on my bedside table for those wee-hour solutions — I’m glad I listened. I try to be pragmatic about what I do and don’t do, which is why I picked a readily available, well-developed car, and I try and focus on tackling areas of the build where I can be additive, rather than re-creating a solution just so I can say I did it from scratch. All of this I think maximizes learning rather than just bolting bits together.”

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. 

Abdul’s E46 M3: Checking All Boxes

A competitive driver, totally dedicated to improving his skillset in the shortest time possible benefits from two distinct things: a dependable car and guidance from experienced mechanics.

“I wanted to be able to adapt to different cars quickly, so I tried most of the usual suspects that first year,” he recalled.

Abdul Osmani recognized that there were about a half-dozen well-trodden paths into high-performance driving after sampling the vehicles during his track day foray. Some platforms aren’t as well supported, as as a brief fling with a GT350 taught him, and there’s a good reason for this. “The Mustang taught me a lot about the problems with modern cars: they’re heavy, they chew up tires, and sometimes parts are hard to come by. I realized quickly that lightweight was the way to go.”

In order to advance at his desried rate, he had to conform and buy a proven platform. This realization pushed him towards an S2000, and it also helped him recognize the one other impediment to his success: his limitations as a mechanic.

So, in the name of expedience, he decided to turn to RCrew for their help. They provided him with a prepped track car and allowed him to apply himself to his new craft without distractions. The S2000’s sharp responses would help him improve, but RCrew’s support ensured his ass was glued to that Recaro seat — and nothing would do more for his advancement than practice.

COVID was starting to dwindle by this point, and now with a largely sorted car that could take the track abuse, he logged as many laps as some professional drivers do in a similar timespan. “I had the means to dedicate myself then, so between 2021 and 2022, I completed 41 track days.”

He’d made the major strides towards his ten-thousand hours and built the muscle memory needed to move into competitive motorsport, and setting fast laps began to lose a little bit of its luster. He decided that the next step was endurance racing, for which the Honda was not as well suited to as were some other popular platforms, he realized.

As the popular HPDE options go, there aren’t many cars with the peak grip and pointiness of the S2000, which makes it a serious contender when pursuing PBs. However, due to its low torque, he had to consider an alternative of a similar vintage.

“As fun as it was to set my fast laps, the chess match of enduros was a new challenge I needed; honing my racecraft would be more rewarding, I believed.”

The E46 M3 was the versatile, if slightly compromised, vehicle that would make a successful and similarly streamlined transition into longer races probably. “There were a few reasons why I thought that. For one, the M3’s easier to drive thanks to more torque and better ABS, and the parts are widely available. Plus, it’s eligible for a few different classes with just a tune. I knew this platform would make it easier to accrue the race laps I was after.”

Once he could commit to a plan, he discussed his options with RCrew, who took his provided chassis and whipped it into racing shape in four months. Part of the reason they could proceed so quickly was because, like with Jacek’s rock-solid E46, they used their tested and proven track car package, albeit with a few extras.

“We went with MCS two-way remotes, AP 5000R Pro brakes at both ends, a TC Design cage, RCrew headers and exhaust, a Bimmerworld rear wing, an RCrew splitter, Volk TE37 wheels: the off-the-shelf RCrew starter pack,” he laughed. “On top of the usual parts, we jumped straight into sphericals, a carbon roof, fiberglass doors, and an AIM dash.”

Weighing in at 2,750 pounds with half a tank of fuel and producing 310 horsepower makes the M3 the perfect middleweight that, as mentioned earlier, can run in a number of classes with as little as a change in engine calibration. It might not have the same degree of mid-corner grip or the turn-in immediacy as the car which it replaced, but the package is better suited to long-distance speed, net-net.

But in full time trials trim, the package still puts down sensational single laps. On a set of Hoosier R7s, Abdul’s 1:34.57 at Laguna Seca is remarkable — especially since he acknowledges that he made a few mistakes that lap. The mid-corner understeer in Turns 3, 4, and 9 “might’ve been caused by being a little impatient on the throttle.”

Furthermore, he’s convinced the slicks might benefit from a little more than the 3.8 and 3.0 degrees of negative camber he’s running at the front and rear axle, respectively. Along with a slightly torquier brake compound — he’s been running enduro pads — the turn-in phase might be shortened, which in combination with more mid-corner grip, might help him find another second.

“I didn’t think 1:33s were possible before this lap, but now, if my stars align…” he hinted.

The salient point is that the car is almost completely sorted, and its dependability has helped him get to the point where he’s able to isolate the smallest setup problems and focus completely on his driving.

This stoutness, plus its kindness to its consumables, has made him convinced that there isn’t another option for someone in his position. “It’s funny that this twenty-year-old car is one of the most sensible options nowadays,” he declared.

His performance in Speed SF’s inaugural enduro endorses this statement. After finishing third, he’s committed to the entirety of next year’s season. “I found the 2.5 hour-length perfect. In comparison to my experiences with longer enduros, the 2.5-hour format makes logistics and planning simple and cost effective. It’s almost like a really long advanced DE session,” he said.

Abdul’s had a few things helping him move efficiently and expediently towards his racing goals over the last four years. Not only has he had the good sense to recognize where his strengths lie — identifying a motivating objective, making the necessary lateral moves, and dedicating himself to the cause, while having the means and the connections to get the sort of help that saves him from headaches. Since advancement has been the aim, and the specific outcome has changed slightly with time, he’s had to think about his approach constantly. Not having to worry about picking the right parts or leaving stones unturned has freed up the bandwidth needed to keep adapting to an ever-changing environment.

Maxxis’ VR2: A New Option for PB Hunters

Those with their ears to the ground have heard about Maxxis’ new Victra Sport VR2, an ultra high-performance summer tire for DE dudes, weekend warriors, canyon carvers, and long-time racers like Justin Ross of Magic Developed.

Built upon the VR1, a famously consistent tire, the VR2 inherits all of its predecessor’s strengths, and takes a step forward in one crucial area: peak grip. This combination of durability and sharp-end grip potentially puts it among the fastest of the current crop of Super-200 tires.

At last weekend’s Gridlife Super Touring Cup race held at Weathertech Raceway Laguna Seca, Justin Ross set his fastest lap on his VR2’s seventh heat cycle: a 1:37.8 in a 2,770-pound (with driver) E36 M3 making 212 at the tires. “We put eight heat cycles in the tires that weekend and we saw little to no dropoff,” he began, “and I know they have another dozen left in them.”

The VR2 has that cross-session consistency and repeatability, and it switches on immediately. Peak grip is available from the second hot lap, and grip does not diminish much at all over the course of a session, making it a versatile tire for logging laps as well as setting the quick one.

“The first hot lap is fast, the second hot lap is the fastest. After that, the drop off is very marginal compared to other tires. If it’s 60 to 90 degrees, you can put about four to five laps, super fast, and drop off is marginal — like tenths of a second,” said Elie Mansour, E46 expert.

“The tires have between twelve to fifteen heat cycles. Like I said, before it ran a 1:20 [at Streets of Willow]. We went two weeks ago, 90 degrees in the same configuration, after five track days — it was the sixth track day, I believe, it ran a 1:21 in the scorching heat!”

Justin and his E36 was the standout this past Gridlife event. 

“Our cars are famous for going into ice mode [under braking], so I noticed [the VR2] kinda minimizes it. Even if you have to swing it or adjust it, it’s very predictable and it gives you feedback under braking,” Elie added.

The design uses a wide outer shoulder, a reinforced bead area, a super-high turnup sidewall ply improves lateral stiffness over the VR1, giving the car great grip and predictability from turn-in through the mid-corner phase.

“At the exit, if i’m completely transparent, the lateral grip on that tire stands above every Super 200 tire that I’ve driven before,” he adds. “Once you punch it, it does get loose a little bit,but I’ve noticed it’s more of a powerslide than a drift; it keeps pushing the car forward,” he explained.

All of Ross' Magic Designed cars relied on the VR2 that weekend. 

Engineers at Maxxis developed a new reinforced Carbon Black compound that reaches operating temperatures quickly. “The RE-71RS is good for about four laps, then it falls off. In our BMWs, the VR2 is as good at the end of the session as it is at the beginning,” Justin added.

“They communicate, too. They’re not noisy, but you do get a lot of feedback through the wheel. They tell you what they’re doing,” he added.

“It’s super easy to control. So even if it slides a little bit, it gives you warning at the edge, and you can control it and keep going. So it comes in handy for, either like a beginner driver –it’s forgiving, or an experienced driver who knows how to modulate it to go faster,” he continued.

The compounds retain silica fillers to maintain solid performance in wet weather, but if that peak grip comes at a price, it might be wet weather-ability. “The VR1 had the tread blocks to move standing water. The VR2 is fine in damp and drying conditions, but it is too focused to be as capable in a downpour. You won’t be caught out if it starts to rain, but there are better options for heavy rain. Put it this way — we went out in a storm and we kept it on track,” Justin said, adding a little laughter at the end.

The same set Justin used at Gridlife Laguna will be used again at November’s Gridlife event at Thunderhill Raceway Park. As he’s seen no diminishment in performance yet, and since he’s tested the sister car on another set which performed over twenty cycles, he’s confident they’ll be able to carry him over another race weekend. That bodes well for any track junkie looking for a stable tire to give them the chance to log laps and set the one they can brag about.

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.

Cody’s C6 Z06: Father-Son Duo Builds Best Of Both Worlds

Being a GM development driver comes with a few perks. In addition to the privilege of getting flown around the world to test interesting new machines, one of the less obvious pros to this line of work is being able to cement a relationship with your father when he decides to turn his Corvette into a special sort of track toy.

Cody Bulkley’s education and career facilitated the development of his dad’s C6 Z06 — a project ten years in the making. His background has helped him from being swayed by forumthink, as the idea of a clubsport build isn’t always encouraged by the armchair authorities. Some claim that the best of both worlds just can’t be attained and, in actual fact, any attempt will result in something that performs poorly on street and track. Cody thought otherwise.

In his mind, a reasonably modern car can be versatile enough to drive three-hundred miles to a track, compete with caged cars, and drive home in relative comfort, but it’s not an easy balance to strike. It takes a special sort of patience and technical insight to arrive at this compromise.

During his five years in a dual bachelor’s program at the Oregon Institute of Technology, Cody joined the school’s FSAE program, which later led him towards a role in the performance end of the automotive industry. General Motors hired him as a chassis integration engineer and he joined the team that developed the C8 Corvette. Concurrently, his dad picked up the Z06 with the intention of turning it into a serious track toy. With all Cody had gleaned from his job, he had to get involved.

“The easy answer to building a track car is to throw a set of Penskes, a cage, and full aero at the car and call it a day, but we couldn’t do that. Dad drives the car to work regularly, so we had to make it more than a back-breaking trailered car.”

While that was a tall order with a relatively spartan and simplistic performance car, the C6 Z06 has good bones, and proved to be much more versatile than he had originally believed.

The first order of business, as his father requested, was increasing power, which was followed by the attendant challenges of cooling a hot-rodded powertrain. A big cam, a ported intake manifold, upgraded trunion rockers, bronze guides, race lifters, ported and polished heads, and long tube headers added another two hundred horsepower to the tally.

To enjoy some 700 horsepower on hot days, the father-son duo had to labor over the cooling package. After plenty of deliberation, the two installed a GSpeed dual oil cooler, Spal fans, a C&R radiator with the GSpeed C7 fan kit, and an LG Motorsports vented hood. Along with engine coolers, they added a GSpeed power steering cooler and a Turn One power steering pump.

The dual-wishbone setup needs little to make it work well with wide tires and a good deal of lateral load.

To keep the car civilized enough for stoplight-to-stoplight driving, they pulled a few OEM products from the Vette parts catalog, including a C6 ZR1’s torque tube, a C7 ZR1’s clutch and mated them to an RPM-built transmission, which has proven capable of handling the power.

Its 600 lb-ft of torque and 7,100-rpm redline would make a 4,000-pound vehicle feel frighteningly fast, but this Z06 weights in at 3,150 pounds without driver. Not many can outgun this car on straighter sections, but many modern cars could make better use of the power — at least before Cody went to work on the suspension.

The combination of stock suspension and big power left Cody with no leeway. Its sudden breakaway made it difficult to attack faster corners, and when the road surface varied much, it didn’t inspire confidence. Along with the optimized spring rates for their LG coilovers and the GM T1 bars at their softest settings, they installed a Wavetrac torsen-style differential. “That diff made all the difference. It made it possible to finesse the throttle. We found a second with that one modification alone, easily. All these touches have made it progressive in the power-down phase, and that’s why I’ve been able to find most of its time in the high-speed sections.”

Subtle aero mods helps this car slip under the radar while encouraging faith at higher speeds.

It has to be said that, despite its stockish silhouette, the aerodynamics have been massaged, though only a little. Nevertheless, the resulting improvement of the center of pressure helped improve the car’s performance in faster sections. “Originally, it was a little aero-loose,” Cody began, “but we moved its pivot point rearward with a rear wing, wickers, and a big front splitter for balance.”

Thankfully — and making the finer points of this process is due to Cody’s education — the improvement in stability didn’t come with any detriment to livability. “We’ve kept all the factory rubber to keep it semi-civilized,” Cody said.

“We had to replace the front and rear brakes with a set of AP Racing six and four-piston brakes, respectively, but they last a long time. OK, we have to pay the Corvette tax in tires, but we’re able to stretch a set of Supercar 3Rs through four or five weekends.”

That combination of moderate weight and mega power has produced lap times that modern supercars and a few full-on race cars might struggle to meet, as seen below:

Not to add insult to injury, but the current lap times don’t tell the whole story. Cody’s personal best at Laguna Seca was set with a failing clutch, and his best at Thunderhill was set on a 90-degree day. When all their stars align, the Corvette may run a couple seconds faster at the featured tracks.

And this very car was driven to and from the track. Cody’s dad even takes it on work trips to Washington State every blue moon, and it still hurts feelings. “As I said, it’s not easy to find that balance between street and track, but we’ve been able to compete with plenty of caged race cars in what is truly a street car. As we incrementally improve the car, we are aiming at setting several class records across West Coast time attack organizations,” Cody concluded.

I'd like to give a big thanks to Roger, Jamie, and Gary for helping me tear down and rebuild the car over the last decade. Couldn’t have done it without you guys.

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.

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.

Alex’s FL5 Type R: Best of Both Worlds

For Alex Peysakhovich, living in NYC had its perks, but easy access to track days was not one of them. When he relocated to Los Altos and found himself with a backyard and a garage, he decided it might be time to purchase that car he’d always wanted and take advantage of California’s temperate weather and multiple tracks within a few hours’ driving distance.

His heart was always with Honda, but the then-current FK8 Type R was too boy-racer for his liking. “I really loved the car, but thought about some things you have to do with your only car, like go to a business meeting or drive in a funeral procession, and I couldn’t really imagine doing those in an FK8.”

So instead he began tracking with an ND Miata. Heavy modification made it a capable cornering machine, but its impracticality became a constant pain; it needed a trailer for long drives and couldn’t be used to take his dog and his girlfriend on weekend trips. He thought about getting an electric daily that he wouldn't track or modify, but that idea didn't last long. “What’s the point of buying a car you’re never going to take to the race track?” he asked himself.

Enter the FL5 Civic Type R, which debuted after a couple years of tracking the Mazda. The new Civic traded its predecessor’s divisive looks for more subdued styling, so Alex had to check it out for himself.

“I used to think Type Rs were a little overhyped, but after seeing it in person, I recognized why the car has a cult following,” he said.

He appreciated the way Honda’s engineers made this fifty-grand Civic feel unmistakably upmarket. But more than presence or build quality, it had real-world usability going for it. On longer trips, the comfortable seats were a welcome upgrade from his Miata’s race buckets. The interior space, the fit and finish, and the performance made the FL5 a great candidate for a daily driver-come-sleeper, and once the premiums started to shrink, Alex pulled the trigger and brought one home.

Before his first track outing, he made a few adjustments. He’d learned enough to know that a ~3,200 pound front-driver would wreck its Pilot Sports fairly fast, so he ditched those for a set of 265-section Bridgestone Potenza RE-71RS tires wrapped around Apex VS5-RS wheels. Along with a set of eccentric lower ball joints to increase negative camber at the front axle, he replaced the stock pads with a set of Ferodo DS3.12s to help clamp the factory two-piece rotors.

He broke it in over 600 miles then took it to Thunderhill West for its shakedown, where he was pleasantly surprised. The steering was quick, despite a dead spot at twelve o’clock, and the gearbox was, well, Honda. If the interfaces were lacking in any way, it was the position of the throttle — as he put it, “in another zip code.” Thankfully, the auto-blip function facilitated heel-toe shifts despite the awkward pedal placement.

Being a front-drive car, he had expectations for how it might handle on a damp morning. Those were dashed on his first fast lap after mounting the dorito at Turn 3, when it hung the rear out in a big way.

“As far as a car that can pack a weekend of camping gear and do great times around Laguna, it’s a hard car to beat.”

The FL5’s mechanical LSD and brake-based stability control system do a commendable job getting the middleweight to rotate. What was less than impressive were the thermal problems which have been associated with the turbocharged Type Rs. Though not catastrophic, the heat causes the motor to pull timing by the end of a long session, but never puts it into limp mode. “I think there’s only so much you can expect from a turbocharged two-liter making over 300 horsepower,” Alex added.

Fortunately, these issues are not new to the Type R lineup and the FL5 was designed to make them easier to address than its predecessor ever allowed. The ducting routes have been established from the factory, along with a functional hood vent. Honda laid the groundwork, but more needs to be done for hot summer days. “It isn’t imperative, but it could use a bigger radiator and an oil cooler. I’ve got those sitting in my garage in anticipation for the summer.”

“The designers cared about the experience of the car; they wanted it to feel special, even when parked.” Alex added. Credit: Tokumeigakarinoaoshima CCA-SA 4.0.

Beyond that, any remaining mods are far from necessary. The FL5 is well-balanced out of the box and does not need much more power. “The engine is certainly strong. If it could use something to make it feel a little sportier, it would be an exhaust — it’s too quiet.”

That subdued exhaust note is part of what makes the car so versatile, and its wide repertoire comes at a premium. Besides requiring pricier fuel, the turbocharged front-driver is hard on its front brakes and tires, and it goes through consumables far faster than a lighter, better balanced car like a Miata.

There’s no denying the running costs are too high to track a Type R regularly — multiple track days per month will continue to be the Miata’s job — but the Civic will be doing daily driving, mountains, longer trips, and rear its head at Laguna and Thunderhill East a few times a year.

Four years ago, Alex thought fifty thousand for a Civic was steep, but he’s changed his tune as of late. “I know that sort of money for a Civic sounds crazy, but you really need to try it. It’s tough to think of something similarly priced that handles so many different tasks as well as the Type R. If I could only have one car, this would be it.”

Richard’s MR2 Turbo: Not Too Pretty To Pirouette

It began all the way back in grade school with Gran Turismo. A few years later, Richard Tran graduated from video games and started moving through the worlds of hard-parking BMWs and drag racing until his expanding network brought a few road racers into his life.

When they invited him to a track day with Speed SF in 2019, he accepted — but not before considering the consequences. Richard was opposed to taking big risks; he’d seriously hurt himself in a car crash a few years before, and he certainly didn’t want to damage his then-new M3, but they persisted — they told him he’d leave the the track feeling something extraordinary.

The feelings of euphoria following that first session helped him forget about the potential costs of thrill seeking. In fact, he’d been bitten badly enough to sign up then and there for another twelve track days. Quickly, he put the dependable M3 on the back burner; he had a cheaper, lighter, more maneuverable mid-engined car he believed would take more to master.

To the trained eye, his 1991 Toyota MR2 Turbo (SW20) didn’t look like the ideal track toy candidate. Actually, it looked more like a museum piece. Three-stage paint, fresh interior panels, and completely new suspension components were all parts of a three-year restoration that culminated in a show-grade vehicle. Richard was so proud of it, he displayed it at SEMA.

Work Meisters and the OEM kouki aero was all that was needed to make the SW20 pop — it truly is a svelte, sexy car.

Despite its immaculate condition, he felt it wasn’t too good to be used in the way he’d (ab)used his M3. In fact, Richard felt that he’d be missing out on something vital if he didn’t track it. There was a directness and a demanding quality about it that made him feel giddy at 5/10ths.

The second outing proved he had his head screwed on straight, but didn’t quite have the quick hands needed to manage the MR2. The factory components just wouldn’t cut it, especially on all-seasons, so he replaced the rotors with slotted Stoptechs and slapped on a set of EBC Yellows. Along with those, he installed a set of Tein Super Street coilovers, a pair of GReddy side skirts, and a 1998-spec spoiler with lifted risers for a little flash.

The basic package was fun, but far from friendly. “I made the mistake of trying to drive it like the M3,” he began, “and that just wouldn’t work. I learned pretty quickly that I couldn’t throw it around or brake as late as I could in the BMW.”

The odd agricultural excursion didn’t dampen his enthusiasm for his demanding new car.

After many red flags and several stern conversations with the track workers, Richard learned he had to soften his inputs a little and improve the chassis a lot. The second-generation MR2 is known as a nervous car prone to rotate without much provocation, but it can be tamed with some suspension work, a little maintenance throttle, and the right sort of staggered tire setup.

Giving precedence to the rear axle began by fitting the rear wheels with 245/40R17 Federal RS-RR Pros — somewhat wider than the 215/40R17 fronts. Then, Richard turned to Elite Performance’s Melody Cannizzaro to soften the sensitive midship’s edges. A little more front camber relative to the rear helped settle the rear end while cornering, and more toe-in at the rear kept it planted under braking and acceleration. Then, as advised by his friends, Richard tried stiffening the front to minimize the nose dive under heavy braking, which could encourage the lightened rear to spin.

Minimizing some of that see-sawing gave him much more confidence in the car, and the resulting improvements in cornering speeds helped Richard notice a few more of its shortcomings.

It wasn’t the tight, direct thing he thought a lightweight MR car would be, but, after all, it was nearing a half-million miles. Sunshine Auto overhauled the entire suspension, adding new control arms, bigger sway bars, inner and outer tie rods, additional chassis bracing, and a set of 808 Racespec coilovers from Bob Pham. “The new setup made the car feel like a go-kart. Actually, the first day back at the track with these mods, I went six seconds faster than I’d ever gone before,” he exclaimed.

Richard’s love for the Sailor Moon series gave this car its eponymous nickname.

“Those modifications transformed it from a decent daily driver to an uncomfortable track car, but I still trust it enough to drive it to the track — it hasn’t left me stranded once,” he said. Pretty impressive for a car that just passed the 500,000 miles on the odometer. Chalk a bit of that up to build quality from the late-eighties Japanese boom, some of that to Richard’s obsessive maintenance habits, and a little bit to the near-stock configuration of the power train.

Aside from a Mishimoto radiator an HKS SSQV BOV, and a Berk 3” exhaust, the original 3SGTE motor remains stock.

Aside from a splitter and a pair of canards, Richard doesn’t plan on adding much more. Actually, he’s confident enough to admit he’s the limiting factor at this stage. “My friends will get in and go six seconds faster than I can, so I know I need seat time more than anything. Well, I could use a set of Sparco Circuits because I’m getting thrown around on the stock seats, but that’s about it.

For me, it’s the perfect track car — dependable, fun, and constantly challenging. I don’t really care about making it the fastest car here. I’ve got a ways to go as a driver, anyways. I’m not here to be the best — I just want to have fun, and in that department, the MR2 always delivers.

My track friends’ words of encouragement and support have been a driving force behind my journey; pushing me to overcome obstacles and strive for greatness. I rolled my car once many years ago and I was in the hospital for months. I thought I wouldn’t walk again.

My wife did not want to see me in another accident ever again. Actually, she wanted me to retire, but she saw how happy I was attending track days with friends, so she now watches me track. I promised her I’ll never go completely flat-out ever again and I’m fine with that — as long as I get to see her smile.”

Max’s Spec Racer Ford: Lose The Ego

After Max Gokhman signed for his 2006 Cayman, his dealer insisted that he take the car to the track. “You won’t be able to fully appreciate it if you don’t,” he said. Max was hesitant — the thought of balling up his brand new Porsche terrified him, but, at the same time, he sensed the man knew what he was talking about.

Max continued to mull over the prospect of tracking his new toy, but his dealer was adamant — so much so he offered to pay Max’s entry fee. That was all Max needed to make a decision. The next weekend, he took the Cayman to Infineon Raceway and began a love affair that never tested his patience. No crashes, no major repairs, and a relatively straightforward relationship with his parts suppliers made his first few years in grassroots motorsports a breeze.

Soft Ascent

After becoming the 2014 PCA Autocross Class Champion and multiple podium-sitter in various Southern California time attack series, he sold the 987 and moved into a 2014 981 Cayman. This time, however, he wasn’t as eager to modify the car. He’d come to understand the practical shortcomings of a track-oriented car and felt he might get more from the ownership experience if he was to leave the car mostly stock.

It was around then that one of his track buddies enticed him into wheel-to-wheel racing. This would entail buying a race-only machine. Truth be told, he had considered it for some time, but the thought of wadding up a Porsche racing car turned his stomach. Even getting on track in one would be prohibitively expensive, so he explored the cheaper options available to him.

He could drive a Spec Miata for a reasonable price, but he wanted something a little different. “I was looking for a mid-engined, purpose-built platform, and — and this is subjective — something a little more interesting than a Miata,” he explained.

He loved the idea of running a “spec” car: something that encouraged close competition through mechanical parity. What about something with the same power of a Miata, but in a car which weighs one thousand pounds less? The tried-and-true Spec Racer Ford, a staple of grassroots motorsport for the last fifty years, caught his eye. Mid-engine, open-top, closed-wheel, and very cost-effective; there was a lot to like about this diminutive, bare-bones racer.

Barest Bones

The tube-frame chassis has a 1.6-liter engine from a Ford Focus sitting transverse behind the driver. These sealed engines produce 135 horsepower, and are fairly inexpensive to replace when they go bang — though this rarely happens. The emphasis here is on reliability, low running costs, and complete driving immersion.

When Max first tested the car at Laguna Seca, he was setting competitive times by the end of the day.

The sense of occasion is something that can’t be underestimated with an open-top car like this. Not only is the visibility fantastic, but getting your helmet buffeted by the wind makes driving at seventy feel like a hundred and twenty. The information relayed by the car is detailed and constant; it’s easy to feel a locked tire or growing understeer through the steering, which is remarkably sharp. “Feedback is crystal clear,” he adds.

Sitting in the middle of the chassis and knowing exactly where your front wheels are at all times inspires confidence to get real intimate with other racers when going three-wide into a turn - truly what wheel-to-wheel is about.

Some might suspect that a car this visceral and direct would come with sharp edges. In reality, it is predictable and communicative, and, as it has much more grip than power, it’s quite easy to find its limits. When it does slide, it’s fairly progressive — more so than the Cayman; nearly 300 horsepower would cause a few dicey situations when passing in a late-apex turn. Some of this is due to a compliant suspension setup, and some of it is due to the Hoosier slick made specifically for the SRF. Incidentally, it isn’t the most expensive tire. Low weight and low power help lengthen its lifespan, too.

The sequential transmission by Sadev, standard in third-gen SRFs, is another racecar element that Max learned to appreciate. Unlike an H-pattern, which is lovely for canyon drives but saps attention from racecraft; or a PDK, which is clinically precise yet fragile on cars that were built for the street; the SRF gearbox lets you bang out shifts while bouncing off the rev-limiter with abandon.

Perspective Shift

Max admits that, while the Spec Racer Ford is the more engaging car to drive, he doesn’t have the same sentimental attachment to it as he had to his Cayman. “I save the sweet feelings for my Porsche. This is a tool to help me grow as a racer. I compare the distinction between the two to owning a pet versus owning livestock.”

And with the reasonable running costs, packed fields, low power, and full calendars, he’s looking to become a competitive amateur racer as he gets up to speed on the Spec Racer Ford platform, with the help of his team Accel Racetek.

“Once I got competitive with this hobby, I learned that money spent on coaching would make me a lot faster than aero, suspension, or other bits of kit. To me, some of those seem most like things to flex over. With Perry and Travis of Accel Racetek, I not only know that the car will be ready for the next race no matter what tomfoolery I get up to on track, but that they’ll keep nudging me to be a better driver.”

Ultimately, the moral here is that with racing, as with any other passion, dropping your ego — such as by going from a venerable Porsche to a humble Spec Racer Ford — may prove to be the path to success, paved with smiles.

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.

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.”

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.”

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

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.” 

Legend's Supra: Big Brain Move

Legend Brandenburg’s ND Miata served him well during his track day foray, but he quickly got serious about the business of turning quick laps and decided he wanted to build his skills with a platform with more tuning potential. Mainly, he wanted more motor.

Not that the ND’s engine is anemic, but it’s not what you’d call a rocketship. He considered the E92 M3, but its ~350 horsepower at the wheels couldn’t compare to what some of the modern turbo cars could offer. After running the numbers, he concluded a 2021 GR Supra’s value, especially when considering the potential for power gains with minor bolt-ons, was unbeatable.

Fast enough to fly.

The chassis felt fun enough for the time being, too. Wisely, rather than opt for a whole catalog of suspension parts before he’d really spent much time driving it, Legend left the Supra semi-stock for the first year. Aside from adding CSG brake pads, Motul RBF fluid, and a set of SPL front control arms for more camber, he didn’t alter the car in his first twelve months of ownership. Instead, he spent his money on learning to drive it. Wise man.

First, he enrolled in a FastSideways course to hone his car control skills. Then he picked a competitive time trials category to put some fire under his ass. Without a hare to chase after, it’s very hard to push beyond what’s comfortable.

You’ve gotta get the bit between your teeth before you worry about setup-related tenths.

His approach proved effective; after just one year of fighting in the S3 class of Speed SF Challenge, he finished fourth; just barely missing out on third. Considering he’d been fighting better-prepped cars on his stock rubber, his first-year effort deserved praise. He’d learned his Supra fairly well, and now was time for the next set of performance modifications.

His goals for 2022 changed with a change in the SF Challenge ruleset that allowed him to remain is S3 with a set of RC-1s a no-brainer. Wrapped around a set of Titan 7 T-S5 Wheels, and a set of HKS lowering springs to help fit the larger wheels and tires, he continued learning his occasionally-tricky Toyota.

“I recognize that there’s still a lot I can learn about the intricacies of this car, and maybe even more that I extract from myself as a driver.”

That year’s fraught S3 battle for second place with neck-and-neck with Joe McGuigan, who just edged Legend in the last event of the year.

So, after driving his Supra essentially stock trim for two years of S3 competition, what did he learn? “It requires a very delicate right foot—and quick hands!” he said. Provided you can keep up with the corrections, the middleweight rotates far better than its weight would suggest it could.

Only this season did he make a real step into track-only territory. “I’d always designated this car as a track-oriented build, but it’s been a strong street car up until I made this year’s modifications. I’ve driven it to and from the track every event without any issues whatsoever. Again, I don’t know if there’s another new platform on the market with the same sort of versatility, tuning potential, and performance.”

To get the heavyweight Supra to handle a little more to Legend’s liking, he installed a set of MCS 2-ways, the entire range of SPL arms—all fitted with spherical bearings. It’s crisper and more compliant now. “I don’t think any other change made as big a difference. The OEM suspension felt overdamped and undersprung, but now the car rides smoother, transitions faster and more confidently, and no longer feels like it’s reluctant to cooperate.”

Keeping all four in contact with the road surface has helped build trust between car and driver.

The car’s famously nervous rear was brought under control with the help of Elite Performance. The dynamic toe change was reined in with a set of SPL rear toe links that help keep settings within a narrower window. With additional static toe-in at the rear, power-down characteristics are improved and so is driver confidence.

Even though he’s felt the temptation to indulge in some easy power modifications, Legend’s keeping the powertrain factory for the moment. “I still have a lot to learn. Plus, it will run laps in 116F heat. Maybe it pulls a little timing, but it doesn’t overheat.”

The studious approach has paid off; in a short span he’s gone from noobie to front-runner. With the fundamentals understood, now he can take his analytical aptitude to the data-side of things, and begin making the myriad minor adjustments that will put him first in class. It’s only a matter of time.
