"The GT2 and GT2 Evos were initially campaigned in the BPR Global GT Series as well as several other smaller national series, and earned seven wins in their class out of eleven rounds in their first full BPR season in 1996, as well as a class victory in the 24 Hours of Le Mans, and again in 1997. In the new FIA GT Championship that year, although Porsche faced factory-backed competition from Chrysler, the 911 GT2s managed to win three races. By 1998 however, the capabilities of the GT2 were unable to combat the increased number of Dodge/Chrysler Viper GTS-Rs in the series, earning only a sole victory.
By 1999 the GT2s had been overpowered by the Vipers, as well as newcomers Lister, however Roock Racing managed to win the GT2 at the 24 Hours of Daytona. An increase in engine displacement to 3.8 litres in 2000 was unable to help Porsche, and support for the project ended. Porsche chose instead to concentrate on the new N-GT category with the GT3-Rs that same year. GT2s continued to be used by small teams up to 2004.
With the launch of the 996 generation GT2, several privateers attempted to continue on the motorsports history by building their own racing versions. Belgian PSI Motorsports' 911 Bi-Turbo and German A-Level Engineering's 911 GT2-R were used to mix success in national series such as Belcar, but were unable to be successful in international series."
