IMSA WeatherTech SportsCar Championship

The IMSA WeatherTech SportsCar Championship has established itself as the preeminent form of endurance sports car road racing in North America. IMSA’s roots date back to its 1969 founding, and since 2014, IMSA has sanctioned the unified WeatherTech Championship which brought together the American Le Mans Series and GRAND-AM Rolex Series championships under one series.

IMSA’s multi-class format features three different classes, Prototype, GT Le Mans and GT Daytona. IMSA also sanctions a number of Challenge and single-make series, which run alongside the WeatherTech Championship on most weekends.

The WeatherTech Championship races in the U.S. and Canada from January through October, and also includes the four-race Patron Endurance Cup that combines the four longest races at Daytona (24 hours), Sebring (12), Watkins Glen (6) and Road Atlanta (10) for a total of 52 hours of racing.

With more than a dozen marques in the series, it’s become a hotbed for brands to develop technology on the racetrack and convert it to the streets, as well as activate at each event.

Michelin has been named the Official Tire of IMSA in a multi-year agreement, starting in the 2019 season for the WeatherTech Championship and the two major Challenge series. Michelin currently competes in IMSA within the GTLM class, which is and will remain an open-tire category of racing.
