If you want a really good resource of rotor dimensions, then go to Disc Brakes Australia's website and find their tech documents for the rotors they sell. The 4000 series is stock dimensions, and they have every dimensions for every rotor they carry (hub diameter, offset, rotor diameter and thickness) for almost every car made.
