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 three classes, Grand Sport (GS), Touring Car (TCR) and Street Tuner (ST), with the series running a 10-race schedule in tandem with the WeatherTech Championship.
