Quote: I agree, drilled rotor are not for the street. Showed a guy at cars and coffee how his ebay drilled rotors were cracking from hole to hole. Scary.
That's why you should never buy cheap Chinese rotors off eBag. You get what you deserve cheaping out on rotors. There have been thousands of good drilled rotors raced for decades with great results. The good rotors have the holes counter sunk drilled to relieve the sharp edges which reduces the cracks.The iron used is important as well. Solid rotors crack too. You can see little cracks on most any type of rotor that's been heated red hot and then squeezed hard during a race. The later slotted rotors will have cracks as well after a race. Wilwood would not sell drilled rotors if they were no good. I've never had a pad glaze up on a drilled or slotted rotor, solid rotors glaze up much easier because the lack of pad surface "wiping" that takes place due to the holes or slots. The pads don't last as long, but if you're worried about pad life this is the wrong forum.
