Event is over and I agree with m3kerry. Not really raining but the surface was cold and damp -- so slick. I tried Sport first couple of runs and didn't like the action. It did activate when the rear tried to step out, but in doing so it seemed to launch the whole car sideways -- two or three feet to the outside of the turn. Suddenly and without notice.
A couple of times I didn't have that extra clearance to spare and I took out outside cones. I can get into just as much trouble with everything turned off, but at least it's me doing it, so I can better anticipate it.
