2013 Rolex Sports Car Series

The 2013 Rolex Sports Car Series season was the fourteenth and final season of the Grand American Road Racing Association's premier series, before merging up with the American Le Mans Series in 2014. It began on January 26, with the 51st running of the 24 Hours of Daytona.

As the NASCAR Holdings acquisition of Panoz Motor Sports, and IMSA, had already taken place, this season is technically one of two series that formed the 43rd season of the IMSA GT Championship that dates to 1971.

Schedule
The schedule was released on September 28, 2012 and featured the addition of three new circuits for the series; Circuit of the Americas, Kansas Speedway, and Road Atlanta. Also, the August 10 event at Road America was a combined weekend with the American Le Mans Series, showcasing the organizations' recent merger. Previous races at Homestead-Miami Speedway, New Jersey Motorsports Park, Watkins Glen Short Course and Circuit Gilles Villeneuve did not return.
