X-drilled & Slotted Rotors CAN be cut!

This is the last I will say about this, and go ahead and believe what you want.

When your tech, tells you that over tightening of wheels can warp rotors you are either not understanding him or he doesn't understand what he was originally told.

Over tightening of the wheel will not causes warping the rotor, what it can do is distort the hub flange on which the rotor sits. This distortion causes rotor runout problems, that when you measure with a dial gauge on the rotor surface will appear to be warped rotors. If left alone this problem will result in further braking issues.

There is no physical way that over torquing of the wheel to the hub will cause physical warping of the rotor. That is my opinion from working on Porsches for almost 20 years, not on what I read on the Autozone website or my local garage mechanic told me.
