The GRAND-AM Continental Tire Sports Car Challenge features sports cars manufactured from around the world, brought straight from the showroom floor, that race side by side with only minor modifications in the area of safety. Like the GRAND-AM Rolex Series, the Continental Tire Sports Car Challenge races two classes at the same time: Grand Sport (GS) and Street Tuner (ST).
