Michigan International Speedway is a two-mile (3.2 km) moderate-banked D-shapedspeedway located inBrooklyn, Michigan. The track is used primarily forNASCAR events. It is known as a "sister track" toTexas World Speedway as MIS's oval design was a direct basis of TWS, with moderate modifications to the banking in the corners, and was used as the basis ofAuto Club Speedway. The track is owned byInternational Speedway Corporation. Michigan International Speedway is recognized as one of motorsports' premier facilities because of its wide racing surface and high banking (by open-wheel standards; the 18-degree banking is modest by stock car standards).
