TheFabric of the IMSA Championships
The IMSA Championships are built around three core series: the IMSA Michelin Pilot Challenge, the IMSA WeatherTech SportsCar Championship, and the historic IMSA GT3 Challenge. Each series offers a unique challenge and appeals to different racing styles.

Participation in these championships isn't just about winning. It's about the journey – the progression through class structures, the camaraderie among drivers, and the chance to race against the best in the business.
TheMichelin Pilot Challenge

The IMSA Michelin Pilot Challenge is the gateway into the world of IMSA racing. This PRO/AM series pairs semi-pro and professional drivers in two-man teams, fostering a unique dynamic where strategy and teamwork are crucial. The diverse range of cars, from Grand Sport (GS) and Touring Car (TCR) to the winning GT4 class, makes this a hotbed of competitive racing.
The Pilot Challenge is where upcoming talent honed their skills before moving up to the WeatherTech SportsCar Championship. It's not just about raw speed; it's about understanding the racecraft, learning how to strategize, and mastering the art of pit stops.
TheWeatherTech SportsCar Championship

The IMSA WeatherTech SportsCar Championship is the pinnacle of U.S. sports car racing. This elite series attracts the world's top drivers and teams, competing in three distinct classes: Daytona Prototype international (DPi), Le Mans Prototype 2 (LMP2), and GT Daytona (GTD). Each class pushes the boundaries of racing technology, with state-of-the-art prototypes and advanced GT cars.
It's not just about the cars, though. It's about the challenge, the prestige, and the legacy. This is where champions are crowned, where records are broken, and where history is made.
