Maybe. I've had excellent results with the 2 piece rotors, no sign of 
warping. You didn't say what pads you were using. For various reasons you 
may be more likely to warp rotors with stock pads.

Thet's what Carl Buckland says, however he's driving in serious 
competition, and I assume that you, like me, are just doing track schools.

Conventional wisdom is that it's a waste of time, they'll warp again next 
time out.
