  1. Rotor measurements should be done with a micrometer rather than a caliper as there is no way to measure only the contact surface with a caliper... Incidentally, a 0-1" micrometer is invaluable for more than just brake rotors.

     

    FWIW: The Porsche rotors are cast, then drilled. If you look at the holes in the picture provided, the holes have clean edges and on one of them, you can see a bit of flashing that hadn't been removed. The casting marks are beyond the path that the drill bit would have taken through the two rotor surfaces.
