The IMSA Michelin Pilot
Challenge Championship (owned by NASCAR), is the premier production based
GT and touring car racing series in North America. Two classes, GS (Grand
Sport following the worldwide FIA GT4 category) and TCR (Touring Car Racing
following the worldwide FIA TCR rules) compete at the same time on track.
Races are between 2 hours 40 minutes and 4 hours long and require a two- driver lineup with several pit stops for refueling and tire changes.
All races are part of the IMSA WeatherTech SportsCar Championship event weekends and races usually take place the day before the WeatherTech SportsCar Championship race.
Touring Car (TCR) - The TCR class consists of homologated cars with engines tuned to produce between 300 and 350 horsepower and are capable of speeds in excess of 140 mph. Competition in this class is equalized by a variety of fuel-tank capacities, power and weight. For more information on TCR go to www.tcr-series.com
