Twin-turbo V8 Mustang wins Tire Rack Ultimate Track Car Challenge

What formula makes the Tire Rack Ultimate Track Car? Every year, we set out to answer that question with the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports.

This year, that winning formula is a built Ford Mustang, driven to the fastest lap time of 1:41.244 by Brian Faessler.

For his efforts, Brian wins the biggest trophy, a $1000 Tire Rack gift certificate and tons of ink in Grassroots Motorsports.

Second place, won by Andrew Dekoning in a Tesla Model S Plaid, wins a really big trophy and a $1000 Tire Rack gift certificate.

Rounding out the top three, and winning a big trophy and $1000 Tire Rack gift certificate, is Ryan Mathews in a Chevrolet Corvette.

Superfly, a celebration of car culture, is coming to the Tire Rack SCCA Time Trials Nationals at Pitt Race this weekend. And registration for show cars is now open.

The Time Trials Nats features many events throughout the weekend. For example, our Tire Rack Ultimate Track Car Challenge kicks off festivities on Thursday, September 18.

Then, on Saturday, September 20, Superfly takes place. Attendees and spectators can arrive as early at 930 a.m. Superfly, however, officially kicks off at 4 p.m. and runs through 9:30 p.m.

Festivities include a DJ, low car limbo, classic video game arcade, mobile dyno (at an additional cost), food trucks, an R34 Skyline giveaway and more.

For spectators, parking is $10, plus an additional $10 for admission.

To display a car, costs begin at $30, and this includes admission for the driver and a guest. All show cars must register before arriving.

#FastFriday: A smile-inducing BMW M2

Sometimes the best track car is the one that delivers the most enjoyment. And for Jerome Cahuzac, that car is a BMW M2.

Currently set up to compete in SCCA Time Trials Tuner 1 and Gridlife Street GT, the M2 features a handful of modifications that includes M Performance coil-overs, M Performance exhaust, a Performance Eurowerks stage 2 tune, AP Racing front brakes, CSF intercooler, CSF engine oil cooler and a more track-focused wheel alignment.

While the M2 “might not be the most competitive in its class,” says Jerome, “it puts a ton of smiles on my face!” And, in the end, isn’t that what really counts?

Jerome and the BMW M2 are one of the latest entries confirmed to compete in the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, our annual search for the fastest track machine on four wheels, September 18-21 at Pitt Race.

Any car and driver that can pass a safety inspection is eligible to compete, so if you meet those requirements, enter your car today. Curious what you’ll be competing against? See for yourself.

The 2025 UTCC will once again be held alongside the SCCA Time Trials Nationals.

Race against Dallas Reed, Marketing Director of Vitour USA

Don’t just race against other cars shod in Vitour tires, race against the face of Vitour Tires in the U.S., Dallas Reed.

Reed, the Marketing Director of Vitour USA, is among the latest entrants into our annual search for the fastest track machine on four wheels, the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports.

Reed’s chariot of choice? A 2024 Chevrolet Corvette E-Ray with just a handful of mods–including Vitour P1 tires, of course.

The 2025 Tire Rack Ultimate Track Car Challenge takes place September 18-21 (that’s less than two weeks away) at Pitt Race alongside the Tire Rack SCCA Time Trials Nationals.

#FastFriday: A Subaru BRZ track car that prioritizes simplicity

Beauty can often be found in simplicity. Or, as is the case with Andres Salinas’ Subaru BRZ, there could be big prizes to be found there, too.

Currently configured to compete in the OnGrid Time Attack series, the BRZ is a “back to basics build,” says Andres, that's competitive on track, low on consumables, highly reliable and enjoyable to drive regardless of skill level.

The not-so-secret formula? Andres is kind enough to share a list of modifications, which includes Nitron coil-overs, an OS Giken differential, AP Racing brakes, 17x9.5-inch Apex wheels wrapped in Bridgestone RE-71RS tires, “a bunch of Cusco chassis braces,” a Zebulon rear wing as well as intake and exhaust components from HKS.

A straightforward approach to building a track car, yes, but is it enough to secure the title of Ultimate Track Car?

September 18-21, Andres’s BRZ will join some of the fastest cars in the country at Pennsylvania's Pitt Race to compete in our annual search for the fastest track machine on four wheels, the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports.

What’s eligible to compete? Any car and driver that can pass a safety inspection. If you meet those requirements, enter your car today. What sort of machinery has already entered? See for yourself.

#FastFriday: Here’s your chance to race against a McLaren 720S

Think you have a track car that’s faster than a modern supercar? Lucky you, here’s your chance to prove it.

Among our latest entrants into the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, our annual search for the fastest track machine on four wheels? None other than GRM’s Tire Test Editor, Andy Hollis, and his McLaren 720S.

“The 720S is a totally streetable track weapon” Andy says of his McLaren, which has racked up numerous time attack wins as well as finishing at the front of the field multiple times in the grueling Tire Rack One Lap of America.

[How we survived the Tire Rack One Lap of America]

Although totally stock aside from Girodisc brake rotors, Cobalt brake pads and Finspeed wheels, the 720S is still good for over 700 horsepower straight from the factory and is capable of hitting 60 mph in less than three seconds.

It the McLaren 720S fast? You bet. Is it fast enough to win the Ultimate Track Car Challenge? We’ll find out this September, when it takes to the twists and turns of Pitt Race to battle some of the fastest cars around for the title of Ultimate Track Car.

What’s eligible to compete? Any car and driver that can pass a safety inspection. If you meet those requirements, enter your car today. And, while you're at it, see who you'll be competing against this year.

#FastFriday: This point-and-shoot Audi RS3 returns for more glory

Point-and-shoot cameras can be an ideal solution for the photographer that wants something that’s both quick and easy to use in most situations, but can the same thing be said of race cars?

Rob Wilmoth makes a compelling argument with his Audi RS3, saying that it’s “the most point-and-shoot car that I've ever driven. The suspension changes have transformed it from a 60% nose-heavy, pushy beast into a rotating machine that flies out of corners.”

In addition to 600 horsepower on tap, Rob’s Audi features custom aerodynamic modifications, BC Forged wheels wrapped in Vitour P1 tires plus brakes, suspension, a fuel system and more from 529 Innovations.

Rob previously placed 17th overall in our annual Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports last year with a fastest lap time of 2:17.400, achieving his goal of setting an even faster time than the year before–and did so while overcoming a transmission mount failure.

But will Rob be able to further improve on his time this year? We’ll find out in September, when his Audi RS3 joins some of the fastest cars around at Pitt Race to battle it out for the title of Ultimate Track Car.

Think you have a track car fast enough to win? If you and your car can pass a safety inspection, enter your car today.

The 2025 UTCC takes place September 18-21 at Pitt Race, once again alongside the SCCA Time Trials Nationals.

#FastFriday: Not a car, but a supercharged, LS3-powered Frontier

Yes, we do call our annual search for the fastest track machine on four wheels the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, but that doesn’t mean trucks can’t compete.

Case in point? Rick Hoback’s Nissan Frontier. Why a truck? “I don't like normal,” Rick says “and I don't like easy, but I like fast.”

Us too, Rick. Us too.

While the complete catalog of modifications and upgrades is too long to list here, we’ll pick out a few favorites.

For starters, gone is the original engine, replaced with a de-stroked and supercharged LS3 engine good for over 550 horsepower and backed by a six-speed manual transmission.

Other highlights include a hand-built oil pan, billet flywheel, “massive” aluminum driveshaft, BMW ABS, three-way adjustable dampers, eight-point roll cage, custom independent rear suspension and a Pathfinder R200 differential re-geared to 3.69:1 and fitted with a KAAZ 1.5 Way Clutch Type limited-slip.

See this Nissan Frontier compete against some of the fastest track cars around at our Ultimate Track Car Challenge, September 18-21 at Pitt Race.

#FastFriday | Porsche 911 GT3: A winning off-the-shelf solution?

An ideal off-the-shelf track car? For Tanner Baker, the answer is a 2022 Porsche 911 GT3.

And instead of an exhaustive list of modifications and upgrades for many track builds we see, Tanner’s 911 keeps things more minimal because, as Tanner explains, “Porsche has done a pretty good job with this one!”

Perfect out of the box? Perhaps. Perfect enough to win the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, our annual search for the fastest track machine on four wheels?

We’ll find out September 18-21, when this 911 GT3, along with several other of the fastest track cars in the country, descend upon Pitt Race to battle it out for the title of Ultimate Track Car.

Think you have a track car fast enough to win? If you and your car can pass a safety inspection, enter your car today.

#FastFriday: Is the Corvette E-Ray the easy button to win races?

For every competitor that enters our Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, we ask a question: What makes your car the Ultimate Track Car?

Most entrants use their time on the soapbox to boast about race wins or detail how much effort has gone into the build.

Dallas Reed, however, kept his answer short and sweet: “It’s the easy button.” And by “easy button,” he’s referring to a 2024 Chevrolet Corvette E-Ray.

The car is almost entirely stock, according to Dallas, with the only modifications noted being a staggered set of Apex wheels, Vitour P1 tires, Verus V1X wing and “a few stickers.” The E-Ray is still capable of producing over 650 horsepower in stock trim, however, and all that power is sent to the road through all four wheels.

What, exactly, is the Ultimate Track Car Challenge? In line with keeping the answers simple, it’s our annual search for the fastest track machine on four wheels.

All that’s required to compete is that both car and driver pass a safety inspection. If you can do that, then enter your car today.

For 2025, the UTCC takes place September 18-21 at Pitt Race, once again alongside the SCCA Time Trials Nationals.

#FastFriday: This Tesla Model S Plaid is a One Lap veteran

Looking for a more electrifying entry to compete in our Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports? You’ll want to talk to Andrew DeKoning and his track weapon of choice, a heavily modified Tesla Model S Plaid.

If Andrew’s name sounds familiar, that's because he’s a frequent flyer in the Tire Rack One Lap of America, most recently placing 2nd overall in this year’s event.

But back to the car, the Tesla has virtually had the entire Mountain Pass Performance catalog thrown at it, from upper control arms to brake rotors and pretty much everything in between.

Likewise, the air suspension has been deleted, replaced with a setup comprised of KW Suspension components, and a specially programmed Motec race computer helps “enhance” the Plaid’s already impressive performance.

While this Model S has the upgrades and chops to find success on track, only time will tell just how competitive it will be when it takes on the rest of the Ultimate Track Car Challenge challengers this September.

What is the Ultimate Track Car Challenge? It’s our annual search for the fastest track machine on four wheels.

Can you and your car pass a safety inspection? If the answer is yes, that means you’re eligible to compete, so enter your car today.

#FastFriday: Compete against an Aston Martin V8 Vantage GT4

A race car that can go the distance? Try this Aston Martin V8 Vantage–because, you know, it’s an endurance race car and all.

More specifically, the Vantage is a 400-horsepower, GT4-spec race car built by Prodrive that also comes fitted with the “Grand Am endurance racing package,” which includes magnesium wheels, (even) larger Brembo brakes, a larger fuel tank and more aggressive aero components.

The driver, Emre Kayaalp (who you may know better as LanEvo here on the GRM forum), describes the Aston Martin as “the ultimate gentleman's racer,” though he is quick to add that “the driver is neither of those things, but hope springs eternal.”

It never hurts to have hope, especially when you’re competing in our annual search for the fastest machine on four wheels, the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports.

If you think you have the Ultimate Track Car, and both you and your car can pass a safety inspection, you’re eligible to compete–so enter your car today.

For 2025, the UTCC takes place September 18-21 at Pitt Race, once again alongside the SCCA Time Trials Nationals.

#FastFriday: A home-brewed, LS2-powered Porsche Cayman

Like so many others during Covid, Mike Murphy started a project to keep himself occupied. While others may have taken up painting or building birdhouses, Mike instead built an LS-powered Porsche Cayman.

“I built every nut and bolt of this car myself,” Mike explains. “Almost all parts are used or hand-me-downs from friends, so I've spent less than $30k in total.”

Starting with an $800 rolling chassis, Mike sourced an LS2 V8 from Facebook Marketplace and bolted it to a stock Porsche Cayman six-speed gearbox. Noting that he “didn’t want it to sound like a V8,” Mike then fit the engine with an 8-to-1 header.

Good for some 450 horsepower, Mike says the Cayman is about as quick as a Porsche 911 Cup Car.

Yeah, that sounds fast, but is it fast enough to win our Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports?

We’ll find out on September 18, when some of the fastest cars in the country will descend upon Pitt Race to vie for the title of Tire Rack Ultimate Track Car.

The goal of the Tire Rack Ultimate Track Car Challenge is simple: To find the fastest track machine on four wheels. All that’s required to compete is that both car and driver pass a safety inspection. If you can do that, then enter your car today.

#FastFriday: Here’s your chance to compete against an LMP3 race car

If you’ve ever wanted to find out if your track car is faster than an LMP3 prototype, here’s your chance.

Ghais Khaleghi, a previous winner of our Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, is bringing a Duqueine D08, an LMP3-class prototype race car.

Power comes from a Nissan-sourced VK56 V8 that’s good for over 450 horsepower, and the total weight–with driver included–is listed at just 2200 pounds.

An Audi TT RS with over 20K track miles under its belt | #FastFriday

This Audi TT RS has gone the distance–literally: 20,000 hard-driven track miles and counting.

“My Audi TT RS proves that performance, durability, and balance can coexist in a single platform,” explains driver Lan Truong. “Despite countless heat cycles, apex hunts, and high-speed laps, it continues to run strong, proof that this machine isn’t just fast, it's engineered for endurance.”

That durability should come in handy when the TT RS competes in our annual search for the fastest machine on four wheels, the Tire Rack Ultimate Track Car Challenge.

Starting with the powerplant, the car’s turbocharged, 2.5-liter inline-five produces over 550 horsepower thanks to an APR Stage 1 ECU tune as well as an upgraded intake, turbocharger and intercooler.

For improved handling, Truong has fit the Audi with 19x11-inch Apex wheels wrapped in Falken tires, Girodisc floating brake rotors, EBC brake pads and the “complete 034[Motorsport] suspension catalog.”

Helping fund the car? Just a single sponsor is listed: “Personal 401k.”

This year's Ultimate Track Car Challenge will be held September 18-21 at Pitt Race, once again alongside the SCCA Time Trials Nationals.

What's eligible to compete in our Ultimate Track Car Challenge?  All cars–and their drivers–must pass a safety inspection. If you can do that, enter your car today.

A carbon fiber-bodied BMW Z4 coupe from TC Kline | #FastFriday

Love carbon fiber? You’re going to enjoy this BMW Z4 coupe entered into our Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, our annual search for the fastest track car on four wheels.

As driver TC Kline–owner of TC Kline Racing–explains, every body panel on the BMW, including the roof and inner fenders, is constructed out of carbon fiber.

Total weight, including the driver? Just 2550 pounds, compared to the 3000+ pound curb weight of the road-going hardtop Z4s.

A torquey N55 motivates the car, which also sports TC Kline double-adjustable coil-overs, Hoosier R7 tires and a track widened by some 4 inches over stock.

What's eligible to compete in our Ultimate Track Car Challenge? All cars–and their drivers–must pass a safety inspection, that's all. If you can do that, enter your car today.

The UTCC will once again be held in conjunction with the SCCA Time Trials Nationals, this year on September 18-21, at a new location, the Pittsburgh International Race Complex, aka Pitt Race.

#FastFriday: How competitive is a hillclimber without a hill?

Photograph by Ron Moreck/Facebook

What do you have when you take a prototype-style racer normally competing in hillclimbs, but take away the hillclimb?

That’s right, an equally potent track machine.

Normally configured to compete in the hillclimbs sanctioned by the Pennsylvania Hillclimb Association, Ron Moreck’s Norma M20 features a 383-horsepower Honda engine and curb weight under 1500 pounds.

But can this hillclimber find success racing on a circuit instead of climbing a mountain? We’ll find out at the 2025 Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports  when it takes to Pitt Race September 18-21, once again joined by the Tire Rack SCCA Time Trials Nationals Powered by Hagerty.

What sort of race cars are welcome to compete? Pretty much anything is free game, from the latest factory-built track specials to ingenuously home-built machines and virtually everything in between. All that’s required is that both the car and driver pass a safety inspection.

Enter your car today.

#FastFriday: Two-time UTCC champion Brian Faessler seeks third win

Brian Faessler and his 800-horsepower Mustang racer are no strangers to the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports, winning our annual search for the fastest track machine on four wheels twice before–in 2020 and 2022.

With recent improvements made to the Mustang, and even more experience at Pitt Race than at UTCC's former venue VIR, Brian is confident he can compete for a third win in 2025.

The Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports takes place at Pitt Race for 2025 and will once again join the Tire Rack SCCA Time Trials Nationals Powered by Hagerty, September 18-21.

Ghais Khaleghi wins the 2023 Tire Rack Ultimate Track Car Challenge

The Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports came down to this: 1000 horsepower versus less than 1000 pounds of weight. Steve Luca brought the former, with a 2020 Ford Mustang Shelby GT500. Ghais Khaleghi came with the latter with a Stohr prototype.

Luca set a blazing lap time of 2:02.759 around NCM Motorsports Park. That broke the production car record at the facility, a 2:02.860 lap set in 2020 by Andy Pilgrim in a McLaren Senna.

However, Khaleghi’s car, with a Suzuki 1000 engine putting out around 175 horsepower, went even faster, with a 2:00.091 lap.

The battle for first may have captured the spotlight, but that was just the tip of the iceberg of the battles during our annual Ultimate Track Car Challenge. Fastest FWD? Fastest AWD? Fastest car on 200tw tires? Read on for the complete list of award winners.
