The Tire Rack Ultimate Track Car Challenge Presented by Grassroots Motorsports is now just two weeks away, October 24-25. However, you can still sign up and join the field that includes this 2013 Radical SR8 of Heikki Rinta-Koski.
Heikki calls his Radical a “very grassroots effort made with production parts.” He adds, the power plant consists of “two Suzuki Hayabusa blocks, with two Mitsubishi turbos and a Porsche GT3 intercooler, [plus a] Syvecs S8 engine management system, upgraded brakes, Bosch Motorsport ABS system.”
Heikki did five hillclimbs with his Radical SR8, including the full SCCA Appalachian Hillclimb Series schedule. Plus, he did a time trial and even an autocross to shake it down. Heikki has proven it’s fast wherever it goes, and what better way to test how fast it is than by running the Tire Rack Ultimate Track Car Challenge on October 24-25 at NCM Motorsports Park in Bowling Green, Kentucky, alongside the Tire Rack SCCA Time Trials Nationals Powered by Hagerty.
