Whether they use drilled or not, race cars throw their rotors in the garbage after 500 miles.
Absolutely, along with what Andy said, drilled rotors have been around since the 60's. The whole point is that they're throwaway items at the racetrack.
Now, if I could get 500 miles out of a set of race slicks, I'd be happy.
