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.
