Obviously there is a range of experience with the OEM rotors. I just replaced mine about two weeks ago and took pictures to post, assuming I was just doing a brake job. I was surprised to see the inside face of both rotors were, for lack of a better term, delaminating. Hopefully these pictures will help some in this thread.

Knowing the VX is over 4K lbs I bought a well machined, OEM spec thickness rotor. They are by Raybestos at $110 each. If you purchase aftermarket rotors check to see that the three smaller holes for the ABS ring are present.

I plan to post all the pictures from the front break replacement, including where to get those three tiny screws that are sure to strip...
