It’s difficult to determine which is more severe, the brutality of the track or the car. This video showcases just how bumpy Sebring International Raceway is and how fast a tube chassis Trans Am car can be.

The camera car, Mark Burt’s Corvette, started life as a K Brothers chassis with a Camaro body, and its first race was at Canadian Tire Motorsports Park in 1986 in the Trans Am series. Burt bought the car in 2015 with the C5 Corvette body. Powered by a carbureted 350 small-block Chevrolet, the car puts the power down through a G-Force four-speed gearbox — those shifts! — and a Winters quick-change rear end.

In this video, which we left at full length because there isn’t a dull moment in it, 2016 ST3 and 2018 ST1 National Champion Mark Burt dices through all classes of racing at Sebring’s historic 3.8-mile-long course. Burt battles early on with another two-time National Champion, Terry Mathis and then contends with lots of traffic — and a few bumps. Turn up the sound and put it on a big screen.

Mark Burt took the ST1 National Championship at Circuit of The Americas in 2018 in his Trans Am chassis Corvette. Burt also won the ST3 championship at Watkins Glen International Raceway in 2016 in a GM LS-powered second-generation Mazda RX-7.
