Sometimes manufacturers post their rotor dimension on the internets.  I
found a reference to an Audi part 121.33021, diameter 276mm, nominal
thickness 24.9mm, hub size 68mm, height 46.3mm.  I have a pair of SA brakes
in a bin patiently awaiting installation.  I should be able to measure them
if you give me a day or so.
