FYI ever rotor thickness is different.

DBA 650's start at 24mm and once they get to 22mm they are classed as "illegal" (well non dodgy shops wont skim them once they get to that thickness). This is why you have to be careful when buying 2nd hand rotors etc. There's still plenty of depth in the groove left, however it doesnt mean they are able to be skimmed again!
