Re: slotting rotors w/ dremel tool???? (trev'sGTI)
No! Don't do it! Doesn't sound like a good idea at all. Drilling into your rotors may cause microscopic cracks & fractures that may grow larger with every heating/cooling cycle during brake use. Eventually the cracks may grow to a point where the structural integrity of the rotor is weakened.......then bad stuff can happen.
Dunno exactly what the manufacturing process involves, but I think the slots/holes are created during the casting/forging/whatever process and not as a final step. Anybody got my back on this one?
