Background
Michigan International Speedway (MIS) is a 2 mi moderate-banked D-shaped speedway located off U.S. Highway 12 on more than 1400 acre approximately 4 mi south of the village of Brooklyn, in the scenic Irish Hills area of southeastern Michigan. The track is used primarily for NASCAR events. It is sometimes known as a "sister track" to Texas World Speedway, and was used as the basis of Auto Club Speedway. The track is owned by International Speedway Corporation (ISC). 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). Michigan is the fastest track in NASCAR due to its wide, sweeping corners and long straightaways; typical qualifying speeds are in excess of 200 mph and corner entry speeds are anywhere from 215 to 220 mph after the 2012 repaving of the track.
