I also second the "don't buy anything" crowd. You are more likely to get rock chips on the interstate than on the track. Most of the time, the worst that happens on the track is rubber scuffing which is easy to get off. I wouldn't worry about it too much. That's just me though. If I'm taking my car to the track, I'm mentally/financially prepared for a crash, and I know that it could get totaled and be a total loss, and I accept it. I wouldn't be having fun peeling around the track if I was worrying about little rock chips.
