Joey's Yaris: Giving the Family Car a New Lease on Life
Joey Rassool was bitten by the racing bug quickly after buying an FR-S a few years ago. Being a deep thinker and someone who never does anything by half-measures, he decided to take an abrupt left turn. Not everyone would see the sense in making the FR-S his daily and the automatic Toyota Yaris the track tool, but he had his reasons.
“I recognized the reality of modifying a car extensively—something I really wanted to do—and so I figured I’d keep the FR-S untouched. I had the family Yaris to play with, and since my siblings were done with it—it was a first car for most of us—I wanted to give it a new lease on life.”
It wasn’t convenience alone that drove Joey to choose the Yaris. After watching an SCCA H-Production race at 2014 Runoffs, he saw that this underrated econocar had real racing potential. So, without much hesitation, he and his brother Sam started modifying the Yaris for autocross. Tein coilovers, 15x8” Konig Hexagram wheels, 205-section Hankook RS4 tires, and a set of Hawk HPS pads were all it needed. A mild dent in the wallet later, they had a machine that would rotate better than most.
If there was one thing holding them back on the cone courses, it was the Yaris’ automatic transmission. Over the winter of 2019, he and Sam threw in a five-speed with an ACT clutch, and while the subframe was removed, they added stainless steel brake lines and new control arm bushings. Sadly, the fruits of their labor wouldn’t be enjoyed for another year.
Cheap seats, sticky tires, and a few bolt-ons were all this featherweight needed.
When COVID died down at the beginning of 2021 and they could finally get back on the track, they took it to the Streets of Willow, where the nose-heavy Yaris revealed a few of its flaws. “I really wasn’t familiar with how it would transfer its weight,” Joey began. It’s not hard to understand why the little Toyota was too happy to spin in the first chicane on the second lap.
“I really hadn’t changed much in the car then—it was all trial and error. I had a Whiteline rear swaybar in place that made the car just a little too twitchy. I started sorting the car out there. In fact, the whole setup problem—not a lot of people track these cars—has been like that. To get my first pointers, I had to consult some of the Honda guys to get an idea of what a car like this needs to go fast.”
“I realized it wasn’t the perfect platform in terms of weight distribution, but at least the problems happened at lower speeds,” he added.
A little twitchiness didn’t keep Joey from diving in headfirst. That year, he ran four of the five events of the TRD Series. The competition there encouraged him to find an ideal setup quickly, and with a set of stiffer BC Racing coilovers, he was able to counteract some of the nose dive and keep the short-wheelbased platform from rotating too much.
The Yaris may only make 100 horsepower, but it’s light. He went to great lengths putting this car on a diet; scrapping lots of the superfluous bracketry, interior, and even the heater core. Now, it weighs a little under one ton sans driver.
To capitalize on the cornering potential of such a light car, he consulted Chewerkz and added a set of shims to the rear as well as some eccentric bolts up front to achieve the camber figures he was after. Aftermarket being what it was, he had to rely on homebrewed ingenuity.
The resulting agility means minimal braking—in fact, this is a critical part of driving. “From the Bus Stop through to Phil Hill, I’m basically flat the whole time. This is a car which forces you to conserve momentum; braking as little as necessary, taking a shorter line when possible, and minimizing tire scrub.”
He’s still aiming to improve the balance. An LSD might solve some of the inside wheelhop and a Scion XB final drive should make the car peppier if not quicker. Its cornering forces cause fuel cutting in the quicker bends, so he plans on adding a baffle kit.
That list of mods might help his performance, which is already impressive for someone with only a dozen track days under their belt. This year, he finished fourth in the TRD Series. Plus, he’s aware that, at this stage, he could do more by working on his driving technique.
“Figuring all this out without much aftermarket support has been challenging, but the car is cheap enough to justify the trial and error. It’s been enlightening, too. Now, I think I understand concepts much better than I used to,” he added.
With this Yaris build, there’s the right mentality and the right sentimentality—he’s driven this car since high school—which makes me think they should go far.
