Gordon’s M2: Iteration Cycle

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Joe’s M3: Proving His Potential

Photo credit: CaliPhoto

When building a track car, it’s almost always easier to take the paved path. Picking a platform that has been thoroughly developed, with available parts for every possible problem and associated forums filled with information help get the driver to the track without much wrenching.

Not that ease was the main reason Joe McGuigan decided to add an eighth car to his collection — he did that because his friends urged him to try the car he’d avoided for a while. They were tired of watching him struggle with his trailblazing passion projects. They said he’d be able to save himself time if he just joined the tribe and bought an E46 M3.

When Spencer Kimball decided to sell the E46 he’d built for his father, whose injuries prevented him from enjoying it, half of the greater NorCal track community flooded his inbox. Spencer had already proven he knew how to put a seriously quick M3 together, and this example checked just about every box a track car needs to. Plus, the price was impossible to argue with. It would make some track rat a very happy owner soon enough, but an iconoclast like Joe? Not likely.

He was well aware of the M3’s potential, but he never found it interesting enough to build one himself. He preferred the challenge of developing a less-loved car, and always found the E46 M3’s competence a bit boring. Too easy to drive quickly, too easy to build. Not enough of a challenge for a man trying to prove a point.

However, the long list of primo parts and the low, low price were too tough to ignore. Joe had to accept the “boring” car for the simple fact that he would no longer be able to handicap himself with a sub-par chassis. “I could show people how fast I really am,” he added. Rather than prove a point as a builder, he could prove himself as a driver.

He mulled it over for a few days before pulling the trigger. Picking it up on the way home was the easy part. Driving it back to his crowded driveway, it dawned on him how big a task he’d set for himself: “Now I’ve gotta put my money where my mouth is and build a really fast car,” he said.

Fortunately, the car was already well on its way towards perfection. Spencer had big plans for the build and sank a good amount of money into making it fast, reliable, and fun to drive. The short list includes:

• Shaftworks USA coilovers with 500/750-lb springs

• Custom Drexler-style 1.5-way differential

• 4.10 gears

• SPL arms

• Supersprint V1 header

• CSL intake

• HTE tune

• E90 GTS rear wing

• Bimmerworld diffuser

• Bimmerworld 3” exhaust

• PFC ZR45 BBK

• APEX Wheels 18x10" ET25 Forged VS-5RS

Those and a few minor mods were all Joe needed to set some competitive times. The first track day was a few days after pickup, so he only had time for an alignment and a fluid flush. Nevertheless, its first outing in his hands, a two-day event at Buttonwillow, was a success.

He found it fast and forgiving, with a linear power delivery and direct steering. Those qualities, plus a hint too much understeer, helped Joe get on top of the car in a session. By the end of the first day, he lapped Buttonwillow 13CW in 1:56.3 — on an old set of Toyo RRs, no less. The predictive timer showed an optimal lap a half-second faster which, funnily enough, is one tenth shy of his best-ever time at 13CW in his well-developed IS-F.

He’s already sussed out its shortcomings and drummed up a short list of solutions which he plans to implement soon. Being able to knock out problems quickly with the support of a vast market is one of the reasons going with a well-loved platform makes sense. “I plan to move pretty quickly with this build. Who knows? I might sell it next year,” he laughed.

The brakes are capable, but the pads might need to be changed as the initial bite wasn’t strong enough to give him much confidence. The spring rates are too low; the owner before Spencer had specced them for autocross. It’ll receive MCS two-ways, a TC Designs cage, reinforced swaybar brackets, and full Zebulon/Buildjournal aero in the next couple months.

But the bones are good, as they say, and it’s already fast enough to aim for some of the times set by friends and colleagues in the E46 scene. While he hasn’t given up on his IS-F, he’ll fixate on beating the established BMW benchmarks for the time being.

Andrew from Buildjournal has taken his E46 M3 just about as far as anyone on the West Coast has, and his car can turn a lap around 13CW in the 1:49s. “I’m sure its capable of something in the low 1:50s with weight reduction, a better setup, and full aero,” Joe declared. There’s no reason to doubt it.

The potential is obvious, the build is nearly finished, his connections are eager to help him, and all he’s had to suffer is a little boredom. The E46 might not pull at the heartstrings like some passion projects, but he can’t deny the potential that the project holds — and the fun he’s already had with it — has caused him to change his tune.

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.

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.

Passing Etiquette: Making Space and Saving Face

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

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

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

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

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

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

Novice Group (Green)

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

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

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

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

Intermediate Group (Blue)

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

HARD RULES: GREEN/BLUE

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

Point-by Recommended/Mixed Group (Yellow):

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

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

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

HARD RULES: YELLOW

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

Open Passing Group (Red + Gold):

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

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

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

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

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

HARD RULES: RED/GOLD

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

Final Thoughts

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

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

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

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

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

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.”

Fenton's Integra Type S: A Change of Heart

“I used to be the biggest hater of FWDs,” he started. Despite his introduction to cars coming in the form of a Civic, he rapidly transitioned into rear-drive platforms when he took up track driving. After a pair of S2000s, he moved onto Porsche Caymans, 911s, and, most recently, a Subaru BRZ. What they all had in common was their rear-drive layout, which cemented in Fenton the belief that all other drivetrain configurations were beneath consideration.

Lately, he’s had a change of heart.

It was an unexpected decision to sell his BRZ. Oil starvation issues concerned him, but he had also owned the car for eighteen months and was starting to wonder what decent replacement was out there—something new, fun, and practical between fifty and sixty grand.

Actually, he was a little more particular than that:

1) It had to be track-capable.

2) It had to have been endorsed by Throttle House, savagegeese, or TheTopher.

3) It had to be at least as practical as the BRZ.

4) It couldn’t break the bank in the event of an incident.

Not much in that price range met his requests, but the faster Hondas, despite driving the wrong axle, were fairly close. But it was more than the drivetrain that deterred him at first.

“I remember when the base Integra was first announced, I thought Acura was disrespecting the Integra name. It looked like a boat; it had no resemblance to the DC2 or the DC5 and, I believed, was probably an overpriced Civic.”

A few months later, the Integra Type S was announced, and Fenton found himself torn. “I started to love the way it looked. Even though the general shape was the same, they tweaked the right areas to make it look like a driver’s car. This had proper flares, an aggressive rear diffuser, a vented hood, gaping intakes—it was unique and purposeful.”

“The Integra wasn’t really on my radar until, one day, I was bored at work and decided to configure a car on the Acura website. I specced out my ideal Type S, and figured I’d add my email to their list—why not?

The next day, Acura of Pleasanton, just seven miles from my house, contacted me and offered that exact car at MSRP plus $1,000 of non-negotiable dealer add-ons. One prospective buyer had backed out and my name came up on their list.”

At the time, he’d been considering the FL5 Civic Type R, though the markup was significant. Plus, the car has a number of creature comforts and tuning differences over the Civic that makes it a better daily. An Integra-specific re-tune of the K20C1 engine, shared between the two, provides much more mid-range torque. Additionally, the Integra’s electronic dampers benefit from new tuning to make it a more supple road car.

The case in favor of FWD was growing, but he still had his bias to overcome. “I used to believe that, if you cannot powerslide it out of a corner, it’s not a sports car.

However, he couldn’t find anything else under $60,000 that is spacious, has a backseat, has a manual transmission, is track-capable, and is rear-wheel drive. I realized that, in order to hit my price point, I’d have to make one or two concessions.

I figured I’d at least give the Integra a try. In person, it looked fantastic, and it felt like a $50,000 car inside. It was something I could live with on a daily basis. The shifter is nearly as good as a Honda S2000’s, the ride quality is phenomenal; with the dampers in comfort mode, it rides almost as well as a luxury car. It has minimal torque steer and phenomenal brakes. After driving it around the block, I was sold.”

He bought it that day.

Since then, he’s beaten nearly all of his previous bests. At Laguna Seca, Thunderhill East, and Thunderhill West, he’s beaten his bests in the BRZ by 2 to 3 seconds. Some of that has to be down to Integra having twice the torque, but, as Fenton’s learned, a FWD car might be easier to come to terms with.

“I can lean on the car more confidently, whereas the BRZ would break away more abruptly. I know that, on turn-in, it’s going to understeer, and while that might sound boring, it means I can get up to speed a little bit faster, especially on cold mornings.”

At Laguna Seca, he drove the tires off his car—literally. Underinflating the PS4S tires to try and keep them in their ideal range seemed sensible, but during turn-in to Turn 6, the front-right tire debeaded. “I only stopped a few feet from the wall. It taught me not to track 30-profile tires with soft sidewalls any longer.”

If there was one issue beyond that, it was the lack of support from the stock seats. “The OEM seats are inadequate for track driving; they are the same design as the base Integra with very little bolstering. The OEM FL5 seats are supportive and soft enough for daily driving and track duty. I’d happily exchange the Integra seats’ heating and electronic adjustability for the FL5’s greater versatility.”

And so he started adding the first round of modifications, beginning with a set of 18 x 9.5” + 45 Apex VS-5RS wheels wrapped in Kumho 265-35 V730s (the same as he had on his BRZ for fair comparison), as well as a set of Ohlins Road & Track coilovers.

The Road & Tracks have a reputation for being more road than track, but the Integra-spec 6kg front and 10kg rear springs are much stiffer than what’s normally offered. “The spring rates have helped a lot with tucking the nose. You can get consistent mid-corner rotation with a lift-off the throttle.”

Along with those mods, he added some Castrol SRF fluid and a set of Endless ME20 pads from RHD Japan since the yen is weak now. Their torque rating is much higher than the standard pads, which were at least resilient enough to run sessions at Laguna without fade.

With the first round of modifications in place, he took it to Thunderhill West and ran a 1:24 in his second session—some 2.5 seconds faster than he ever went in his hardcore S2000 on Federal tires. “It felt adjustable; it wasn’t a battle against understeer in every corner. You can transfer weight with the inputs and rotate the car in small, measurable increments. That’s something I find a modern GTI just won’t do.”

Most recently, Fenton ran Thunderhill East Bypass for a day that he found encouraging, if not a little frustrating. After spinning in the first session and getting the black flag, he found himself without traffic in the second session and logged a 2:01. “I believed I could find another one to two seconds in the third session, but one of the flaws of the car held me back.”

In order to completely avoid fuel starvation, the tank needs to remain above half-full. After dipping below the middle hash five minutes into his third session, he spent the remainder dealing with fuel cut. He couldn’t leave too miffed; he’d only had one real session to push the car, and with that 2:01 indicated on his Garmin, he’d already gone three seconds faster than he ever had in the BRZ.

Considering he’s only done three modifications and is already three seconds faster than the BRZ, he has no regrets. “I might not be powersliding it everywhere, but it’s taught me that there are other, subtler ways of manipulation.”

Beyond all this, I can drive to and from the track in complete comfort. With radar cruise control, lane-keep assist, blind spot monitoring, heated seats, a premium ELS sound system, and even a sunglasses holder—I’ve never been so comfortable on my way to and from the track before. Going from a partially gutted S2000, to my mostly-practical BRZ, to this, I’ve experienced three distinct improvements in comfort. Plus, I can ferry people around. There is plenty of space for four adults—roughly the interior space of an Accord from fifteen years ago.”

It’s still a little too quiet to hear with his helmet on, so he’s planning on upgrading to a modest exhaust that should make it easier to gauge where he is in the rev range, reduce backpressure, and find a little more grunt. That said, it’s not lacking in that department; it has more than enough torque to run third gear through most of Thunderhill West. Oh—it could use more front camber.

In Fenton’s eyes, it deserves to be seen as Acura’s flagship sports sedan—it’s a deserving successor to the DC2 Integra Type R. “It’s a compromised car at the end of the day, and yet they have kept all those compromises from adversely affecting driving enjoyment. To me, it’s the perfect compromise.”

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.

Tailai's Supra: Keep it Simple, Keep it Sane

Started tracking in 2018 after moving to the States to study at UC Davis. Being an undergrad student, Tailai time was booked solid. Even so, he had an image of Sonoma Raceway, an image he’d had in his mind since playing Gran Turismo in his early teens, and he knew he’d have to find a way to experience it.

With no real knowledge of the trackday landscape, he booked a three-day advanced driving course at the Simraceway Performance Driving Center, where he was able sample the circuit and the strengths of his daily, an E92 M3. “I didn’t know anything then, so I kept the stock pads and went to drive. The only thing I added was a big wing, because it was cool.

The car was stable and forgiving, and the classes went off without a hitch. The subsequent visits to the track weren’t always failure-free, though. “Whenever I tried to push, something broke.” He endured the bills and, without much of a racing education, he started modding the car to make more power — something entirely predictable. He slapped on a VF supercharger and, after it was installed incorrectly, he blew the motor.

Disappointed, he sought out something reliable with more tuning potential. He didn’t like how American cars drove, so no Camaro. The atmospheric BMW engines weren’t all that interesting to him, but the potential of some of the turbo cars caught his eye.

“I first bought the Verus full aero, which I now see was foolish. I should’ve started with suspension, but the aero kit was too cool to ignore,” he laughed.

He didn’t exactly settle on another car from the same marque, but he wasn’t far off. After finding an impressive deal on a 2021 Supra, he pulled the trigger.

The first outing in it, he left it completely stock. Very capable already—capable of lapping Sonoma in the 1:53s. By this time, he’d started studying what would keep his ass in the seat and what would drop times the fastest.” I wanted the car to be reliable, so I didn’t touch the powerplant. There were more important things to change.”

Maybe the pleasure of seeing the car kitted out was the right move, because it wouldn’t let him down like his first set of coilovers would. The first set of KW Clubsports broke after a few days. Fortunately, his growing social media presence helped him secure a more track-oriented setup; KW reached out and offered him a set of Competition coilovers.

Then, seeing how easily he was squeezing noticeable performance from the package, he got a little smarter with his tuning approach. He hit the books hard and called on his years of building soccer robots for RoboCup Junior. With his analytical mind whirring away, Tailai could not ignore the way Supra’s weight was working against him. “Weight savings starts out cheap, but it gets pricey pretty quickly,” he admitted. Just by pulling the carpets, seats, adding a cheap Chinese fiberglass hood, and changing the battery, he trimmed an impressive 200 pounds from the car, and only spent an afternoon a few hundred dollars.

Less mass saves some strain on the binders, which don’t need too much help. Pads from CSG, stock rotors and calipers, a basic ducting kit, and even with Goodyear Supercar 3Rs and the aero loading, the brakes last an entire session without fade.

Mods were kept minimal. A set of SPL control arms for more camber and toe adjustment, a Sparco bucket seat, and a chopped exhaust rounded out the short list. Fortunately, the A90 just doesn’t need much help from the factory — just a sportier alignment:

With Jackie Ding’s advice, he increased front camber to -3 degrees, increased the rear to -2.8, set the front toe at 0, and, to minimize some of the bump steering, a smidge of rear toe-in. About 0.3 degrees, actually.

Tuning took some time to understand, but like his choice in modifications, he fumbled his way through it until he could learn enough to make the right decisions. “At first, I had the rear wing angle turned up to the max before adding the splitter, so at 8 at Thunderhill East, the car just went straight. That scared me. After that, I started to read up on aero balance.”

After adding a splitter and trimming out the rear wing, he found a sweet spot that gives him some reassuring push in faster corners. Combine that with a car that is easily rotated on throttle in the slower corners, and it’s not hard to see why he’s gone so much faster in the span of a year.

“As soon as I touch the throttle, I like it to rotate a little,” he explained.

And with that, he had a platform he could take to the track and run lap after lap. It’s super reliable. After forty-minute sessions at Thunderhill in 100F weather, the brakes and the engine remain cool. The Supra is happy to take the abuse.

His dedication to the craft, complemented by his studious approach and background in robotics helped him go from a total novice to someone fighting at the front of Speed SF Challenge’s S2 class in just two years. You don’t make that progress without cracking the books and being a little ingenious. Now pursuing his PHD in electrical engineering, he is confident he took the right path. “If you don’t have a budget to hire an engineer, you have to learn to do it yourself.”

Tailai has done most of the work in his garage. “From chassis tuning, I gained probably two seconds.”

And although he sees the importance in building a dependable, approachable, reliable car, he knows that racing is not just an engineering exercise. It takes practice, physical fitness, and coordination. So, after he adds the new Spage aero, the rest will come down to him. “There’s still a lot more potential there that I’m not getting. Honestly, I’m still a pretty bad driver,” he said.

For someone who’s currently lapping Sonoma in the 1:45s, but had no idea what an apex was a few years ago, that is a masterpiece of self-effacement. Not everyone advances this quickly in the sport, but Tailai’s taken the sensible approach and put track time first. If that isn’t a compelling case for reliability, I don’t know what is.

James Snell's Supercharged S2000: Bold is Better

Four years ago, James hadn’t even considered tracking a car. Though he was definitely a dedicated gearhead, he preferred lowriders and rock crawlers, mainly. Some of his friends had taken the track day plunge, however, and a few of them were adamant he branch out a bit.One Saturday morning, he drove out to Streets of Willow with a few eager buddies and everything changed.

The giddiest of his friends also had good taste; he brought his S2000 along and threw James the keys. He also had trust and good manners—he only asked that James bring it back in one piece. The casual introduction had clearly had an effect, because, just one month later, James had bought one for himself.

Good Hands

It was no ordinary S2000, either. This AP1 was previously owned by a Ballade Sports employee, so it’d been given lots of love and attention. Along with some choice body modifications, it came fitted with KW V3s, a square set of RPF1s, an exhaust, an intake, a halo-style seat, and an F22C motor with roughly 40,000 miles. For someone dipping their toes in the water, James couldn’t have been luckier—the price he picked this one up for would irritate a lot of prospective buyers these days.

The car came with an OEM AP2 front bumper and CR lip, a replica CR trunk wing, and a full carbon hardtop weighing only seventeen pounds.

As nicely sorted as this example was, the AP1 is not a forgiving car. “The first few times I drove it, I probably spent more time spun off-track than I was on-track, but I didn’t care. I set a 2:14 at Buttonwillow 13CW and I felt like a rock star. I may’ve been going off a few times every event, but—and I can’t stress this enough—I was having the time of my life.”

“My motto then was: ‘If you’re not spinning, you’re not trying.”

However, he adapted rapidly. “Smooth is fast in that car. The more I softened my inputs, the better the car responded. My lap times fell, and I set my sights on a pretty significant goal early on. The aim was to set a Buttonwillow 13CW lap under two minutes on 200TW tires without the help of any aero.”

As James learned, trimming the first few seconds is easy. Three years passed before he was able to whittle his times down to something nearing his goal, but he didn’t care too much. Again, the thrill of driving and learning the nuances of the S2000 were the wind in his sails.

One of his biggest hurdles with the car was learning how to gel with its nervous behavior. “I was usually leaving some on the table because the rear was on a knife edge,” he said. It would give him the willies when the S2000 would rotate at higher speeds, but James realized that he had to suppress his instinct to lift his right foot. Backing out in that situation doesn’t always work well in this very pointy car.

After getting enough experience with the car’s edginess at higher speeds, he returned to Buttonwillow on a set of A052s which were well past their prime. Even after spinning the car six times, he didn’t falter. That day, he was determined to find those last few tenths.

When he saw a 1:59.7 appear on his AiM Solo, he whooped. “I went from setting a 2:14 in the same car, essentially. Sure, I moved from a Nexen to an Advan, but the car was identical otherwise. That gave me the permission, if you like, to take the next big step with this car.”

Forget Incremental Improvements

At this point, James was nearing his sixtieth track day in the car. To give it a commemorative special touch, he decided to douse it in a shade of green most often seen on Porsches. “I’d wanted a GT3 RS in Lizard Green, but I couldn’t justify the cost—I could buy a duplex for that money.”

Getting the professionals to paint it that color wasn’t cheap, either. Instead of forking out enough to buy two new motors, he set up a makeshift paint booth in his garage, studied YouTube, spent a thousand in materials, and gave it a whirl.

Not surprisingly for a car with such battle-worn exterior, prep took far longer than anything else. So much of the original panels were beaten beyond the point of sensible continuation. In the place of the old panels, he added J’s Racing front fenders and rear bumper, as well as a set of ASM rear over fenders. Over the course of four months, he spent three-hundred hours replacing panels, sanding, and swearing. The painting itself only took a few hours.

Then came a Voltex Swan Neck and a Racebred Components 3” front splitter. Along with the aero, he added a set of JRZ RS Pro coilovers and a Karcepts front sway bar which made a “night and day difference—it was almost a new car. I think the V3s were well past their prime, and I might’ve handicapped myself with those. When I finally got the right equipment, I immediately dropped my best at 13CW to a 1:55.7.”

Ready for Some Overdue Jam

The motor had been through the ringer and in July 2020, the motor dropped a valve. He spent the summer rebuilding another 2.2-liter Honda short block with a Port Flow Design cylinder head built by Tom Fujita. With Supertech dual springs, valves, and retainers, he’d be able to beat on it without worry. However, it was still lacking a little jam.

For that reason, he unsheathed his credit card one Black Friday and ordered an HKS GT2 Supercharger. That was the first of many modifications needed to double an F22C’s output.

With the guidance of Son Vo and FormulaS, the new engine package was fortified with a V-mount intercooler, plenty of ducting, 1300cc injectors, an AEM V2 ECU, and all the custom piping needed to keep the motor running cool.

Plans for a Forced Induction Future

The beauty of this supercharged motor is that it will remain as tractable as it was pre-blower, but with nearly twice the power at the top-end. Because of its linearity, it should be tractable, even with the stock differential.

To ensure over 400 horsepower is put to the pavement cleanly, he’s also widened the footprint a little with a set of Titan7 T-R10 wheels measuring 18X10.5”. Though he hasn’t settled on a specific tire, he’s thinking a square set of 295-section Hoosier A7s. Not only will the car put the power down, but it will stop in a fashion that might let him reuse his original braking points. Well, maybe.

“After seventy-five track days, I’m still ear-to-ear. Actually, I’m like a kid on Christmas the day before a track day. I purposely don’t drink caffeine from noon onwards so I can sleep. It doesn’t really work; I end up getting up at 3 AM and watching racing videos on YouTube until I leave.”

“What I’m looking forward to more than anything is that, once I pass Sunset, I’ll no longer feel like checking my e-mails.”

With the major drop in time he enjoyed after the last big step in modification, maybe his new goal of a 1:49 at CW13 is in the cards. Whether it is or isn’t, it’s certain that he’ll be grinning the whole way there.

First Impressions: 2023 GR Corolla

A long and fruitful relationship with One Toyota of Oakland put Patrick Chio towards the front of the waiting list for the 2023 GR Corolla. Only 6,000 were made for this year, and at that dealership alone, the waiting list was 150 names-long.

As evidenced by the length of the hopeful would-be owners, the American market has been craving a true hot hatch from Toyota, and Patrick was fortunate enough to learn that the out-of-the-box performance more than justified the hype.

Though Patrick wanted the top-tier variant of this newest GR product, he could only get his hands on a “Core” base model within his preferred time frame. This particular car, finished in Ice Cap white, has none of the frills of the fancier versions, save for the optional Performance Pack and its Torsen limited-slip differentials front and rear.

In a paddock filled with supercars and winged track cars, the furor surrounded the subdued Corolla.

With very few visual cues to alert the observer, there’s really very little that sets this car apart from most econoboxes on the road nowadays. The bodyshape is ordinary, the exhaust is muted, and the absence of flashy badges and bright font won’t alert even well-trained eyes. Compared to the rally-inspired Evos and STIs of twenty years ago, it’s subtle. How times have changed.

Thirty years ago, “turbo” would’ve been pasted in bright colors across the side of the car.

A short wheelbase, 300 horsepower, a small turbo that spools immediately, and an adjustable chassis made its on-track foray at Thunderhill Cyclone exhilarating and impressive. It’s the last trait, its mid-corner adjustablilty, proved useful in long, tightening corners like Turn 2 and the direction change between Turns 5A and 6.

There’s only so much entry speed that can be expected from a stock alignment and OEM tires, but when the front axle was overloaded, all it required was a brief lift and the car would pivot in a progressive, predictable fashion.

Though a vehicle with such a short wheelbase would be expected to oversteer noticeably after such a throttle adjustment, the breakaway is very gradual and “more of a neutralization,” says Patrick. The car is soft-edged out of the box, but the potential for a very lively and pointy machine is clearly there. The combination agility and an ability to leap out of slow corners were what allowed Patrick to keep a decently driven AMG GTR within striking distance.

Of course, being a four-wheel drive car with a turbo, it helps to try and drive a different line which favors the corner-exit phase. Favoring a squarer line with a late, abrupt turn-in helps minimize the time spent loading the front axle. While this wears the rears a little faster, it does allow for a rapid exit without any front tire scrub slowing acceleration. With torque and traction in spades, it pays to prioritize the corner exit. Always play to your strengths.

For around $35,000, it seems like a bargain. It does have the shortcomings of most hatches—namely its build quality. Being a hot hatch, the suspension is not what most people would consider comfortable. “You feel every bump and surface feature on the road,” Patrick says. Thankfully, the supportive factory seats and comfortable ergonomics help soften that rough ride somewhat.

On the road, the 1.6-liter engine pulls like something three times its size from low revs. It is very usable on backroads and in city driving, but the small turbocharger runs out of puff at around 6,000 revs. For now, the shelf of mid-range torque—its 273 lb-ft are available between 3,000 and 5,500 revs—is appreciated exiting hairpins and while making mid-corner throttle adjustments.

The G16E-GTS engine makes 300 horsepower and 276 lb-ft of torque from just 1.6 liters. Not surprisingly, fuel economy is poor. “My C7 Z06 gets better consumption,” Patrick reported.

The motor stands to get a little tweaking in the coming months, though stateside aftermarket support is still limited. Some shops have already reported the factory ECU is crackable. That and a bigger turbo ought to provide a sufficient power bump until the rest of the country catches on with GR Corolla tuning, which will adopt some of the know-how tuners in the UK, Japan, and Australia have already used in their development of the GR Yaris. Considering the fervor surrounding the car, it shouldn’t take long.

Before the engine is touched, Patrick and Titan 7 will widen the footprint and improve the stance. Titan 7 has been working to spec a wheel for this new platform that both suits the car’s shape and fits nicely around the factory four-piston brakes.

Crucially, the tires can’t out-accelerate the engine development. “Even the stock tires were not giving up much,” Patrick acknowledged. The traction and poise offered by the factory 235s complement the power output and weight well. Because the stock tires aren’t easily overwhelmed by the factory power output or the weight, it makes sense not to get too big with the replacement rubber. Impressive considering the weight of the base Corolla with LSDs comes in at 3,262 pounds.

For the time being, a set stronger wheels, stickier 255-section tires, a few custom arms and bars, as well as a little weight reduction should help this long-anticipated Corolla squeeze into the position of supersleeper. If it leaves the factory with 100 horsepower per cylinder, makes good use of all that power, and handles the heat well, it has all the makings of something truly special.

Many thanks to One Toyota of Oakland for helping us acquire this vehicle and sparing us the outrageous markups that other dealers have tacked onto the Corolla’s cost.

Near-Win at the 25 Hours of Thunderhill: Team Tazio Ottis Racing's Day-Long Battle

Four days before Friday’s Final Practice, Team Tazio Ottis Racing was treated to a reassuring practice at Sonoma Raceway with Speed SF Track Events. It had been the cherry on the sundae after a successful season in WERC E0.

The second year of competition had given Tazio and his team to sort out their FK8 Civic Type R. Their transmission, the FK8’s weak link, had been fortified with stronger third and fourth gears, which has served them well the whole season.

Concerned for the health of the drivetrain, they decided to cap the power at a healthy and reliable 300 horsepower and seek out more speed by reducing the total wet weight to 2,850 pounds with Seibon carbon parts and a titanium Remark exhaust. Along with that car, they had a team of four strong drivers: Tazio Ottis and Daniel Wu, the team’s regulars, aided by Patrick Chio (Speed SF) and Will Wattawongkiri (WRTeknica) for the 25.

Unfortunately, they seemed to have snagged a bad part. During final practice for the 25, third gear blew. After a successful season without gearbox issues, it came as a surprise.

The team was stretched thin hustling to repair the box with a used third gear—one with eighty race hours on it. The effort took them until 11:30 that night, and the delay had kept them from attending qualifying and relegated them to the last position on the grid. Thankfully, they had a long race ahead of them.

Rolling around to take the green flag in last, Will Wattawongkiri was feeling the weight on his shoulders. All of a sudden, the car wouldn’t move. It turned out the driveshaft wasn’t seated properly, so it came out and they brought the car back in the pits and lost six laps. Clearly they weren’t off the start that they wanted.

There was something to lift their spirits, though: the speed was there. Compared to their main rivals on the DIG Motorsport team, their pace was comparable and so their fuel economy was superior. Perhaps the Mustang’s dry performance was better, but things didn’t stay dry long enough for them to benefit much.

The weather was tricky; starting wet, staying wet, and eventually drying slowly, but the Honda was well suited to these conditions. An OS Giken differential and the added weight over the driven wheels helped when the track was slippery. All this was more impressive by the fact that the hasty gearbox repair kept them from getting a good alignment. As a result, they had to swap the fronts out every two hours.

With a prediction of thirty percent rain a little before midnight, they opted for their grooved Toyo RRs—their dry tires. “The difference in lap times was as much as twenty-three seconds, but it was a little risky to go to dries. The dry line was obvious, but it was extremely cold and wet off-line. Passing off the dry line would result in a massive loss of traction, so we had to pick their passes especially carefully,” Patrick said.

Thankfully, they gambled intelligently. In the slippery conditions, the Civic enjoyed a real advantage over the DIG Mustang, which struggled to put the power down. Additionally, the team’s overall pace—very similar across all four drivers— was not limited by the equipment. “We never had to soft pedal the whole race—we all pushed really hard,” Tazio noted.

TTOR were clawing their way back to the front of their race when the fuel started dropping to a worrying level and the fog rolled across the surface. When the fog was deemed thick enough to warrant postponing the race, they had to park the car on the front straight and leave it alone until the race resumed.

“We were catching up lap by lap until three in the morning when the fog rolled in. We were only two laps down when the race was stopped,” Patrick said.

Around 7 AM, the conditions were deemed acceptable for a restart. The team gathered around their new car and stuck Patrick Chio in the seat.

Their Type R had parked on the right side of the track and DIG’s Mustang had parked on the left. A prototype ahead stalled at the restart and boxed the left lane, though that hadn’t stopped the NASA marshall from continuing to wave the right line to move, resulting in a reshuffling of the grid that didn’t sit too well with the DIG team. However, the Civic needed to refuel and had to pit as soon as the green flag dropped. (Note: During a full course yellow condition, the pit lane is closed, prohibiting any team to do any work on their vehicles).

Around that time, DIG lodged a protest about passing during the restart, which Tazio and the team chose to debate initially, but did not persist in fighting the call. They accepted the compromise presented to them: a half-penalty drive through, which they served an hour afterwards.

Thankfully, they could make up for this minor setback. The similar pace among the TTOR drivers meant none of them had to double-stint. To improve matters, they could lap fast enough to push DIG’s fastest driver into running a triple stint and driving quite defensively. The Type R was catching up lap after lap and finally when, with Will Wattawongkiri at the wheel, they eventually passed the DIG Mustang in the twenty-third hour; giving them the class lead and a ninth-place-overall standing.

The actual action in some endurance races only lasts a dozen laps, but that was not the case here. Tazio enjoyed a multi-lap battle with DIG’s Michael Whelden. “Michael was making his car very wide and I was trying to get in his head by flashing my high beams. Honestly, that whole stint felt like a sprint race!”

Roughly one hundred minutes from the end, TTOR made their final pit stop. While stuck in the pits, the DIG Mustang regained the lead of E0, though they hadn’t yet pitted for refuel and we were aiming to repass them and lead the race til the end. They planned to pass; pace was still very strong—until third and fourth gear broke . They had to back off, using fifth in most places, minding the car, and watching their delta grow and grow.

Fifty minutes from the finish, they had to make a decision. “We could have continued running in fifth gear, but the transmission was making a lot of noise. We wanted to avoid blowing up the gearbox and leaving oil all over the track, so we decided to retire the car,” Patrick explained.

“It just made sense. Plus, we wouldn’t have been able to make up the deficit. It was the right thing to do at that point,” Tazio added.

“While we spent many hours in preparation for the race, picked great endurance components, hired a lineup of strong drivers, our team executed perfect pit stops, the 25 was not guaranteed—it never is. The mechanical failures during the last hour made our hearts sink, and we still feel the pain of losing—we were so close to crossing the finish line in first place,” Patrick reflected.

“We couldn’t have done it without our excellent crew and our sponsors. We’ve learned a lot about the car and the competition, and we’ll come back stronger next year.”

Dan Avon's E46 M3: A Study in Taking Things Slowly

One doesn’t need to have a big V8 or a turbo to go quickly at most of Northern California’s medium-speed tracks. They don’t necessarily need a featherweight, either. The E46 M3 sits somewhere between the two. Weighing in at 3,200 pounds and making a healthy 300-odd horsepower with moderate torque, it straddles the fence between momentum car and muscle car. With the right touch and a few chassis mods to help bring out this middlewight’s best attributes, namely its handling, it remains a hard car to beat. 

Dan Avon took a comprehensive approach to tuning his 2004 M3; engine power, grip, balance, and braking performance were all valued evenly throughout this build’s three or four stages. Most importantly, he’s learned how to gel with the car by fine-tuning its handling so that it complements his driving style. 

Its first iteration as a mildly modified road car was fun, though he felt the plush nature of the M3 was limiting its on-track performance. That didn’t concern him much as he was still driving it to work, to the grocery store, and through the canyons. The motor made ~285whp with a set of Status Group Tuning headers and a Dinan muffler, and with a full interior,  it weighed ~3,400 lbs with driver and a half-tank of gas. Despite those less than stellar figures, the broad powerband of the motor and the playfulness of the car were satisfying enough to overlook its shortcomings.

Except some. The factory suspension was not up to snuff, so he added TC Kline D/A coilovers, rear camber arms, and polyurethane trailing arm bushings. Even with these modifications, it was very much a street car. His growing fascination with developing the car and improving his lap times meant he’d stuff track wheels in the car before driving it to the track, but it was still doing double-duty. 

He started stripping the car slowly and systematically to help give it a feeling of agility. Being a plush car, it wasn’t hard to remove a couple hundred from the total. It then became clear that the Brembo brake kit wasn’t really as inspiring as he thought they’d be, plus the consumable costs were high, so he eventually swapped those for a set of PFC binders. 

With an AFe Stage II intake and a Epic Motorsports tune, he now had 300 horsepower at the rear wheels. Again, he made sure to address every area of performance through the various stages of modification, so even if the improvements seemed insignificant on paper, it felt more alert, competent, and encouraging. The M3 was always meant to be more than just the sum of its parts.

Weight reduction became more and more important to him as he learned to push harder, so after five years of worsening this car’s civility, Dan decided that the M3’s days as a street car were over. He chucked most of the carpet, door panels, and roof liner to get it down to a respectable 3,100 pounds with driver and a half-tank. 

Increasing his cornering speeds and just generally working the car harder revealed some of the limitations of the factory differential. When he installed the renowned OS Giken 1.5-way differential with aluminum bushings, he could generate much more propulsion off the corner, even if the rear was moving around slightly.  At the same time other areas of the rear suspension were addressed with various mono-ball bushings in place of the previous poly bushings.

Not that it was ever tailhappy. His setup was neutral to oversteery; an extremely satisfying and manageable balance that helped yield some great lap times. Still, he wanted to experiment with a little aerodynamic grip—even if that risked the near-ideal balance he’d achieved..

With a Bimmerworld rear wing and a homemade front splitter, the car had even more stick in the braking zones and the few high-speed corners at Thunderhill and Sonoma. The upside was that the lap times immediately fell by a couple seconds.

Unfortunately, that aero grip came at a price. The once playful car was suddenly arrested at the front end; a persistent mild understeer kept him from enjoying the car like he once did.

In an attempt to take some weight off the car, particularly off the front, and restore some of that neutral handling he once enjoyed,  he added Supersprint V1 headers and Section 1 midpipe, a Bimmerworld cat back race exhaust, a Ground Control hollow front sway bar, a rear-mounted Antigravity battery, and Bimmerworld carbon headlight blanks. These measures saved nearly 200 pounds in total, but the push was still plaguing him.  At least the car was significantly quicker.

Frustrated with the balance but happy to see this car evolve into a no-compromise track toy, he continued to stiffen and harshen. Why not?  He’d already decided to start trailering this dedicated track car, so he had no reservations about adding a rear half cage from TC Design, Turner Motorsport solid aluminum engine and transmission mounts, a set of MCS three-ways, and a Racetech 4119 halo-style bucket. 

Life has gotten in the way in the last year, but he’s still fascinated by the car—and hopes to return to regular lapping days in the near future. “I’ve always enjoyed tinkering and seeing what improved the car and what didn’t. I’ve used my AIM system to determine exactly where the tweaks paid off. I guess that’s what motivated me most of the way.” 

He’s still frustrated by the current balance, so he’s pondered two possible paths to follow once he gets back into the swing of things. Either he removes the aero and tries to optimize the mechanical grip of a lightweight car, or he finds the biggest, meanest cattle plow of a splitter he can find to give the front some much-needed aero grip. Either way, he’ll be measuring incremental improvements and sticking to his basic philosophy of addressing every aspect of performance and taking baby steps. Seeing how quickly this middleweight, mid-powered M3 navigates Northern California’s best tracks, it’s certain this steady, methodical tuning approach works.   

FEDERAL TIRES SPEEDSF CHALLENGE @ THUNDERHILL RACEWAY - MARCH 18, 2018 - ROUND 3

The SpeedSF circus arrived back in the town of Willows, CA with its barrage of exhaust notes echoing in the morning sky. As residents woke up to the mechanical roosters, modified vehicles filed into the renowned Northern California racetrack, their respective drivers eager to lay down their personal best lap times for the Federal Tires-sponsored SpeedSF Challenge.  

We had Groups S2, S3, S4, and S5 represented, and the results were about what was expected, though S4 did bring a resounding class win to temporarily de-throne the class leader, at least for this round!

Group S2

Group S2’s showing featured the two class leaders and rivals from last season, Gordon Peng and Steven Chiu. On Saturday, Steven’s BMW told him “nope” during one of his sessions and therefore needed to take a quick trip to the auto parts store down the street. On Sunday, Steven came back with a vengeance and took 1st place in his M3 ahead of Gordon’s C5 Corvette. Gordon’s best lap time during the SpeedSF Challenge was a 1:23.105 while Steven’s was a 1:22.018. Steven and his trophy-winning wheel hub are sure going places this season, especially if he can continue breaking Andrie Hartanto’s M3 class lap record along the way just like he did at Thunderhill West!

New wing!

Hey, that's not Steven! 

Group S3

The Dirty Mango did it again with Gary Yeung at the helm, pulling off a 1:22.150 during the SpeedSF Challenge session. While Gary took home 1st place, John Lawrence and his 2017 Camaro SS 1LE set a 1:23.661 and took home 2nd place, extending his S3 lead this season to 67 points. Gary, however, only has 25 points to his name thus far this season, which currently ties him for 3rd place.

Group S4

Sohan Kota was dethroned for the first time this season! He and his S2000 fell into 2nd place despite setting a fast 1:27.683 lap time. However, on this day, Gabriel Rothman was just a helluva lot faster this time around in his Ford Focus RS, setting a 1:26.857 lap time and clearing 1st place without doubt. Joe McGuigan, the fastest of the rest, secured 3rd place in his Scion FR-S and setting a 1:30.010 for his troubles. Will we see another blistering pace from Gabriel in his next SpeedSF Challenge showing?

Group S5

Ah S5, the Miata-dominated class… not that there is anything wrong with that! Eric Fernandez took home 1st place with his Mazda Miata, setting down a 1:28.677 lap time and earning him the title of the fastest Miata of the day. Scott Smith, however, was not far behind in his own NA Spec Miata! He took 2nd place with his 1:29.950 lap time showing. Imagine if he had his “YT Rice” Miata this round. Ryan Tan took home 3rd place in his own Miata after setting a 1:32.559 lap time, which is a good showing as well! Ryan must have set a faster lap earlier in the day because 4th place driver Ben Bunch set his fast lap time of 1:32.306 during the SpeedSF session. Either way, it looks like it’ll be close battle for 3rd place if Ryan Tan and Ben Bunch can continue dueling with close lap times like these!

All-in-all, another great showing for the SpeedSF Challenge participants. We appreciate fast lap times as always and of course enjoy seeing lap records fall. We’ll just have to wait and see who is willing to step up to the challenge (pardon the pun) as we progress through the season. With 12 more opportunities to go, the season is still up for grabs!

As we look forward to Round 4 of the SpeedSF Challenge at Thunderhill, we want to say that we truly appreciate our sponsors and participants as it would not be possible without them! 

We would like to thank our Challenge sponsor Federal Tires, as well as SpeedSF Track events sponsors Wine Country Motorsports, G-Loc brakes, DBA USA, Necksgen, and iLapTimer 2.

Our next SpeedSF Challenge will be held at Thunderhill Raceway (West Loop) on April 29, 2018. Again, please check out the event website by clicking here. We will see you at our next event!

In the Stock class, driver Tor Anderson, who is part of both the Championship Prize program and the Tire Contingency program took home 1st place and 10 points. His fastest lap time was a 2:17.96 on the GT Radial SX2.

In the Street class, the 2nd and 3rd place drivers were in close contention with one-another! Even better, they were both on the same SX2 tire! While Neal Wiebmer ran away with the fastest class time of 2:10.80 and 10 points with his SX2 tires, Sean Chou and Aseda Abaoyge’s lap times were close. Sean ran a 2:11.12 earning him 2nd place and 7 points, while Aseda, who was not far behind at all, laid down a 2:11.80 on his fastest run, which earned him 3rd place and 5 points in the championship. That is some fast driving on display! All three drivers are participating in the  Championship Prize program and the Tire Contingency program.

In the Touring class, Trevor Parque took 1st place and 10 points home in addition to netting a 2:12.07 on his fastest lap time. P. Stitch took home 2nd place and 7 points for his efforts. His fastest lap time was a 2:21.89. Stitch is also a participant in the Tire Contingency program.

Last but not least, we have the Unlimited class. In it, Kevin Schweigert whose boosted chassis pushed him to a 1st place finish and a fast lap time of 1:59.22, taking home 10 points for the class win. Garland Wong’s V8-powered FR-S allowed him to get a lap time of 2:00.31 and 7 points as a result of his 2nd place finish.

Federal Tires SpeedSF Challenge @ Thunderhill Raceway - February 25, 2018 - Round 2

Round 2 @ Thunderhill east

Round 2 of the Federal Tires SpeedSF Challenge was held at Thunderhill Raceway as part of an exciting two-day weekend. A huge entry list for this round netted some incredibly close points-grabbing, in addition to SEVERAL track records being broken, making it one of the more intense SpeedSF rounds of recent memory. Additionally, the Federal Tires contingency earned two drivers free tires! 

Sohan Kota won two free tires for his Group S4 1st Place finish, while Eric Talistu won one free tire for his Group S5 3rd Place finish!

                                                                    Federal 595-RSRR

BROKEN RECORDS at Thunderhill East:

Group X:     1:51.710 (Jeff Cook - 2002 Corvette Z06) 02/25/18

Group S1:     1:53.259 (Andrie Hartanto - Corvette C6 Z06) 02/25/18

Group S2:     1:56.925 (Patrick Chio - Nissan 350Z) 02/25/18

Group S3:     1:59.551 (Edwin Pham - Honda S2000) 02/25/18

Group X:

Group X featured two drivers: winner Jeff Cook in a Corvette C5 Z06 and Gary Yeung in his world-famous Honda S2000. With Shah Rukh Khan's absence for this round, this allowed Jeff to grab 25 points, tying the two gentlemen for 1st place. Pretty boy Gary secured 2nd place for this round. 

Group S1 featured a repeat winner, Josh Grobin in a Porsche GT3, and two newer drivers, Philip Spencer in a Lotus Exige and Nikolas Beisert in a 2015 Ford Mustang GT. Philip scored 2nd place,  while Nikolas scored 3rd place. Great driving by both of them! Andrie Hartanto accepted the award on Josh's behalf during this round, causing great laughter and confusion as to who the real Josh Grobin is!

Group s2

Group S2's winner was SpeedSF's very own Patrick Chio in his made-for-Thunderhill Nissan 350Z. Historically, his car has performed very well at Thunderhill East and this time it was no different. Group S2's runner-up was Gordon Peng in his Corvette C5 Z06, an amazing run featuring fresh tires, a determined set of eyes, and brass hardware whose gleam could be seen for miles. He snatched an easy 21 points, putting him squarely at the top of the S2 group as we head into Round 3. 3rd place winner was Jourdan Risoen in a 2011 Subaru WRX. It is still a young season, but if this round was any indication, the S2 points battle will be very close as each round progresses. 

The shirt clearly explains why he was able to secure a podium finish!

Group S3

Group S3 is a loaded group of track stars. It features the usual track toys piloted by some of the finest drivers SpeedSF has to offer. Edwin Pham secured a 1st place finish in his Honda S2000, followed by John Lawrence's 2nd place finish in his big bad 2017 Chevrolet Camaro SS 1LE. Tim Crane took home 3rd place his own FWD beast, a Honda Civic EK hatch. 

Group S4

Group S4, although a smaller group of drivers, already has a runaway winner heading into the Round 3 of the SpeedSF Challenge! Sohan Kota won 1st place again in his Honda S2000 (AP1), while Alex Lin took 2nd place with his own Honda S2000. With a name echoing famous racing liveries of yore, Gabriel Rothman took 3rd place in his Ford Focus RS. 

Group S5

Finally, Group S5, a group featuring a really cool Ford Escort race car straight out of Georgia, and, of course, a sea of Miatas! Miata hero Corentin Derbois continued his reign this round with a 1st place finish in his Mazda Miata, with Ronald Nielsen in a Ford Escort ZX2 trailing not far behind in terms of points! His 2nd place finish at Thunderhill vaulted him to 2nd overall in S5, leapfrogging Iakona Simpliciano by 5 points. 3rd place finisher Eric Talistu rounds out Group S5, finishing off an exciting round 2 at Thunderhill. 

As we look forward to Round 3 of the SpeedSF Challenge at Thunderhill, we want to say that we truly appreciate our sponsors and participants as it would not be possible without them! 

We would like to thank our Challenge sponsor Federal Tires, as well as SpeedSF Track events sponsors Wine Country Motorsports, G-Loc brakes, DBA USA, Necksgen, and iLapTimer 2.
