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.”

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.

Jake's S2000: Balance and the Best of All Worlds

The first 5-10 track days went well. Jake Montinola’s E36 M3 was so forgiving, so comfortable, and so beautifully balanced that the start was without many worrying moments. That changed when he tried an S2000 on the tenth event. He was hooked immediately, and the ease with which he entered into racing was replaced with trepidation. But that justifiable concern was tied to a sort of excitement that Jake knew he needed more of in his life.

The breakaway in the S2000 was faster, the reactions faster, and the need to drive it more smoothly forced him to alter his style consciously—one of the first things he changed. Gary Yeung and Gary Wong were huge influences who helped reshape his style to be smoother, neater, more considerate of things like the rate of brake release, and much more concerned with keeping the rear underneath him. Some people can drive the S2000 with a lot of slip angle very effectively, but the inherent pointiness of the car requires a delicate touch, regardless of driving preferences.

Gary Yeung of Elite Performance also lent a hand with the servicing and upgrades. For a long while, all the car had was an HKS exhaust and a set of Winmax pads. That was enough—Jake had been struggling to keep the fidgety car pointed in the right direction. “I probably spun it every other session the first couple times I took it out,” he laughed.

The softness of the S2000’s stock suspension became an issue he didn’t want to deal with any longer, so to try and minimize some of its willingness to oversteer, he installed a set of Ohlins DFVs. The body control improved, but he came to find that he liked the S2000 with stiffer suspension underneath it. In the Ohlins’ place, he moved onto the HKS SP coilovers that “made a world of difference.”

That didn’t mean it became an inert lump of metal. The car turned fantastically when he replaced the stock wheels with a set of Weds Sport TC105s and 255-section Advan A052s. “Turn-in was immediate after that. Then Gary [Yeung] helped me neutralize the car with a few setup tweaks. I added a front sway bar, which helped stabilize the car. I then played around with the rear dampening, as well as a more aggressive alignment with more rear camber helped improve rear traction.

Always a fan of the ASM cars, Jake made his look like one with their front bumper and wider fenders.

In addition to having this extra pointy front end at his disposal, he had a fantastic braking system with real anti-dive to help the platform stay solid so the driver could absolutely stomp the middle pedal at the beginning of the brake zone. “The stock brakes were great, but eventually I upgraded. The Stoptech ST40 front, a reasonably priced setup, has paid off some of the initial cost with pad savings over the last couple years. “Plus, the brake feel stays consistent through a session, and I never have heat problems. I might’ve cracked one rotor, but I think it’s a great kit for the price.”

The motor went on for years, but once he passed the 170,000 mile-mark, it let go. He turned to Gary for a rebuild, who was mindful of Jake’s budget, so he used OEM parts where he could—including OEM AP2 valve springs and retainers as they’re a little stronger. Along with those, he added a Ballade baffled oil pan as well as a valve cover baffle to reduce blow-by.

Over time, he got tired of the Silverstone Grey and went with a variation of Porsche Chalk.

Though some friends felt he ought to try and spend more time learning the car before adding aero, he couldn’t resist grabbing a J’s Racing Type 2 wing. The snappiness at the rear was still noticeable—though Jake acknowledges it could’ve been his driving—so he went to the next logical step. With Megan Racing rear toe arms and rear roll center adjusters, he could correct the geometry with the rear sitting as low as it was.

With that, he’d nailed the setup. “I had 100% confidence in the car. I was attacking the esses at Sonoma and actually had a few scary moments, but I kept pushing. The car was perfect.” With a subsequent string of flawless track days, Jake hit his personal bests at Sonoma, Thunderhill West, and Laguna Seca in a short time.

Well, almost. Jake’s always loved the looks of the ASM S2000s—cars that have been able to get around Tsukuba in 56 seconds without the help of a turbo, so he grabbed himself an ASM IS11 replica front bumper to help balance the rear downforce with a little more front bite. Along with that, ASM’s vented front fenders made it possible to add a square set of 17x9.5” Volk ZE40 wheels wrapped in either Yokohama A052, Nankang AR1, or the new Nankang CRS. With all the grip available, Jake now was a little worried about something snapping.

The most renowned failure points, the hubs, had to be replaced. The front hubs are new Honda items and the rears are Karcept’s replacement hubs, which are filled in solid where the weight-reducing cut-outs are on the backside of the already thin OEM hub flange. These beefier items remove the factory rotor retention screw holes for reportedly twice the strength of the standard hubs. Along with those, he replaced the wheel bearings with standard Honda items and added ARP extended studs at all four corners.

There’s not much more he feels is needed to make this car just about perfect. A better set of Penske 8300 coilovers are currently on their way. Following that, he’ll upgrade the bushings, add a 4.3 final drive, and install a Cusco 1.5-way differential. Hopefully this diff will save him the headache of popping stock diffs—he’s been through a few already.

“I feel it’s better to keep it closer to OEM,” Jake asserts. “That way, I’m working more on my driving and worrying less about something going wrong.” The package has been built well and sports some strong parts, which should make it more than enough for consistent, stress-free, fun driving.

That’s it for the winter mods, but then there’s the change in mindset: he has a plan to go back, attack, and hit a few new PBs. He’s just been calming down a bit, enjoying the drives, and using it as a coaching tool lately—and that is no criticism of the car. It only shows that a car can be equal parts fast, fun, reliable, and challenging. Only some cars can wear a few hats well, and this lightly-tuned, rock-solid S2000 is certainly one of them.
