I have the R1 Concepts rotors that are drilled and slotted. I have been very happy with their braking power, even on the race track. However recently they have started to pulsate just like the GM stock rotors do after a little while. They took longer than the GM rotors to start pulsating and are definitely 1000 times better than GM rotors.
My question: Is it possible to have the stealership cut these rotors just like they cut stock rotors? Will it cause problems with the holes? Will the rotors crack or something?
