2011 Rolex Sports Car Series
The 2011 Rolex Sports Car Series season was the twelfth season of Grand-Am's premier series. Continental Tire became the official tire partner for Grand-Am, replacing Pirelli after three seasons due to Pirelli departing to FIA Formula One, GP2 Asia Series and GP2 Series as well as increasing GP3 Series involvement as an official tire partner after FIA World Motor Sport Council meeting verdict in Geneva, Switzerland on June 24, 2010. The company purchased the naming rights of the RSCS's support series, the Grand-Am Cup Series, from KONI in 2010.
The season began with the Rolex 24 at Daytona on January 29 and finished with the EMCO Gears Classic at the Mid-Ohio Sports Car Course on September 17.
A notable change is the television coverage. In contrast to 2010, about half of the races were not televised live.
