That's basically what GT racing is... well... at least the lower classes. The top class is the only one with Audi R8s and stuff. WRC is cool, drag and drift are cool, but I can't think of anything better than a good GT race.groundhogday1976 wrote:What I meant by production based is not purpose-built race cars, but cars that rolled off the assembly line and were modified for racing. Like Speed World Challenge Touring Cars. Granted they aren't very close to stock form at that point, but they still have the same engine (only highly modified) and drivetrain layout they came from the factory with.
