Works pretty good. Fast around the corners, fairly stable, feels like a Group C car but that only makes the car better imo. It works nicely on the normal livery. Mine is sitting at 700 PP. 897 BHP and weights 950 KG. A bit heavier then the Stealth model but a bit more powerful too. In short words: it works.I have a tuned Audi R10 TDI Stealth Model in my garage. I havnt tried it on the '06 version but it may work.. Feel free to give it a try. If it works, let me know.
