Having driven at Road America in Wisconsin in real life, Westhill is the closest track to a real track, like the aforementioned. Its....its just a great feeling to drive on Westhill. It is challenging, but relaxing. And put a FOX on it and you lift off the throttle, what, maybe 2 times?
And I cant complain about the grass, because it keeps you far away from the barriers, so you can burn off speed before you smack them.
