ESP

On the track, though, turn it off. Besides being very hard on the brakes, ESP very aggressively prevents oversteer, with the result that the car feels like it's developed a bad push. Eventually ESP will even cut the throttle, as my brother discovered at Mid-Ohio when he just coasted thru Turn 15 and onto the front straight after he forgot to turn it off.
Having said that, though, I do leave ESP "on" during the first session on a track in the rain. Discretion is the better part of valor, and I don't want to find a very slippery corner the hard way.
