Maybe someone else has heard this before, knows something about it, and can set me straight... To my understanding, drilled rotors are not suited for those of us who go offroad. I have read about small rocks getting wedged in the holes of vented rotors and ruining things. It would seem if this were to happen it would happen more often in rally, but I don't read up on rally very much so I am not sure where I heard it. Anyone have any comments on this?
