IMSA Continental Tire SportsCar Challenge

From the showroom to the speedway, the Continental Tire SportsCar Challenge is IMSA’s showcase for the latest in American-made and imported high performance sports cars, coupes and sedans straight from the dealer showroom floor. With modifications permitted only in the area of safety and competition, the Continental Tire Challenge is home to the same cars seen on streets and highways around the world every day. Racing takes place in two classes, Grand Sport (GS) and Street Tuner (ST), with the series running a 10-race schedule in tandem with the WeatherTech Championship.
