mavric240I use this car for almost all of the endurance races and love this car. It will beat everything but the supercars. Set brakes between 9 and no higher then 11. set the final gear around 3.200 and the auto to 19. this should get it going. SLam the ride height all the way down and then two clicks up this will keep it from scaping. TCS to 5 and the accl and decell to 8. this should help you out
