If you look t the rotors on a TRUE race car like a Formula1 Indy car, or even a NASCAR stock car for that matter, they all have one thing in common, smooth faced blank rotors. Indy and F1 cars might use ceramic or carbon kevlar rotors which resist heat greatly, so drilling those would just take away from overall brake performance. NASCARS use the same type of rotors that come on your car from the factory, though in a 2-piece floating disc version which will dissipate heat MUCH better than a one-piece slotted or drilled rotor will. F1 cars might actually use slotting marks on their rotors to aid with cooling, but NONE use cross drills.
