Horse, I'm not saying I don't agree with you, but I just haven't seen any real proof (data) showing the benefits (if any) of cross-drilled/slotted rotors on our cars (OEM SIZE).
Until somebody gives me proof, or real life experience, I'll stick with my opinion.
I had cross-drilled rotors once... They looked cool, and that's about it. Still faded like a sumbtich after a few stops from high-speed.
Not saying there is no improvement what so ever, but I simply don't think it justifies the higher cost.
