Hubert's MKIV Supra: Soft Spot

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.
