I'm with JollyRoger on this one. I've had my drilled and slotted rotors for over a year now (with stock pads) and have not had a problem with them. I don't drive the VX hard enough to make the rotors do what they where designed for, so they are more of a cosmetic treatment than a functional one. You would have to race the VX and do some seriously hard braking (continuously) to put drilled and slotted rotors to the test.
