Remembered by many as simply, the Viper from Gran Turismo. It's now sort of in Assetto Corsa. This is all three cars that ran at Le Mans in that year, #51, #52, and #53. This skinpack is of course for the fantastic RSS GT1 mod, which you should check out... Now!
Seriously? Why are you still even here? You should be getting the RSS GT1 mod.
Special thank you to @speedyx56 for a few files to make the interior and headlights nicer. His better made livery of the famous 1999 Team Oreca car can be found here.
