Rolex Sports Car Series
The Grand-Am Sports Car Series ( last: Rolex Sports Car Series) was an American racing series for sports prototypes and Gran Turismo. It was held from 2000 to 2013 by the Grand American Road Racing Association. The Series will go up in the United SportsCar Championship from 2014.
After 1999, the existing United States Road Racing Championship failed, a successor was founded with the Grand American Road Racing Championship. Core element of this series was the 24 Hours of Daytona. Approved were sports prototypes as well as in the European FIA Sports Car Championship ( SRI / SRII SRPI and / SRPII ). There were also additional classes for Gran Turismo ( GTS / GTO and GT / GTU ) and the AGT class for tube -frame chassis as in the Trans-Am series. Following the decline of the number of starters in the sports prototype a radical cut was made in 2003. A completely separate category, the Daytona Prototypes, was created. This presented henceforth the fastest cars of the racing series.
As of 2005, there was also only one class for GT cars which moves in the direction of technically GT3 regulations. For the 2013 season also the GX class was created, which could be in GT vehicles with alternative drive systems used ..
On September 5, 2012 it was announced that the series with the American Le Mans Series will be united. The new series was presented on March 14, 2013 under the name United SportsCar Racing and will debut for the 2014 season.
