The 2000 Grand American Road Racing Championship season was the inaugural season of the Rolex Sports Car Series run by the Grand American Road Racing Association. The season involved five classes: Sports Racing Prototypes I and II (SR-I and SR-II) and three Grand Touring classes referred to at GTO, GTU, and AGT. 9 races were run from February 5, 2000 to August 17, 2000.
The Grand American Road Racing Championship officially replaced the brief United States Road Racing Championship which had folded during their 1999 season. The Grand American series used similar rules, although the class names were all changed. Taken from http://en.wikipedia.org/wiki/2000_Grand_American_Road_Racing_Championship_season.


The 2000 American Le Mans Series season was the second season for the IMSA American Le Mans Series. It was a series for Le Mans Prototypes (LMP) and Grand Touring (GT) race cars divided into 3 classes: LMP, GTS, and GT. It began March 18, 2000 and ended December 31, 2000 after 12 races.
This season was the only time that the ALMS held races outside of North America, with two events held in Europe and one in Australia. These events helped with the creation of the 2001 European Le Mans Series season, although it was short lived. An Asian Le Mans Series was also discussed but not developed.
