Contour Enthusiasts Group Archives Forums Modifications Brakes Cross Drilled rotors, they can be machined.

For those who have indicated that drilled rotors cannot be machined, I received a message from my brother, whom is a Master Automotive Technician with over 25 years in the business. He was able to machine a set of drilled rotors without any issues. This confirms information that I had previously received from KVR Performance. The only difference when machining a drilled rotor versus a standard rotor, is to not take off as much per pass, and that's it. Otherwise, the same brake lathe was used.
