three races. By 1998, however, the capabilities of the GT2 were unable to combat the increased number of Chrysler Viper GTS-Rs in the series, earning only a single victory. By 1999, the GT2s had been largely overpowered by the Vipers, as well as newcomers Lister. Despite this, a GT2 prepared by Roock Racing managed to win the GT2 class at the 24 Hours of Daytona. An increase in engine displacement to 3.8 liters 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-R that same year. GT2s continued to be used by private teams until 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 with mixed success in national series such as Belcar, but were not competitive in international series.
