I've had a hankering to beef up my brakes and the SPMotorsports kit seems just the ticket. Problem is (apart from finding money), I've seen more than a few complaints about aftermarket rotor warpage only after a few hundred to a few thousand miles (this just won't do. I'm not in the habit of swapping rotors every month or so). To those who have used x-drilled or slotted rotors on their contours, what are your experiences?
Thanks.
