Many will enter, but only one will leave with the title of Ultimate Track Car.

Sounds simple enough, yet the winner will have to compete against some of the fastest track cars in the country, from highly-modified sports cars to potent factory supercars, gas-powered to all-electric–and, yes, even a truck.

It all goes down on September 18 at Pitt Race as part of our annual search for the fastest track machine on four wheels, the Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports.

Too late to enter? Think again–as long as both car and driver can pass a safety inspection, you’re eligible to compete, so enter your car now.

While there can only be one winner, there are several prizes and awards up for grabs that go deep into the field, and entrants get ink in an upcoming issue of Grassroots Motorsports–meaning both you and your car will be magazine famous.

The Tire Rack Ultimate Track Car Challenge will be held alongside SCCA Time Trials Nationals. New for 2025, the weekend will also be joined by Superfly, a celebration of ’90s and 2000s car culture.
