From the showroom to the speedway, the IMSA Michelin Pilot Challenge is IMSA’s showcase for the latest in American-made and imported high-performance sports cars, coupes, hatchbacks and sedans. This series is home to the same cars seen on streets and highways around the world and offers racing in two classes – Grand Sport (GS) and Touring Car (TCR) – running a 10-race schedule in tandem with most of the WeatherTech Championship events.
