Rear rotors: R53=R56? - motoring|underground

They have the same dimensions (294x10) but different part numbers. I know the R56 front rotors fit an R53 with JCW calipers, but those have a different part number from the R53 JCW rotors also. I ask because Stoptech makes a nice slotted rear that is listed for the R56, but I'm thinking it could work on my 04.

Anyone checked this out?

good question! I'd like to know also< I'll have to ask my friend (MINI tech) if he knows.

Cool. Let me know what you find out.

I am 99% sure the rear rotors are the same r53 and r56 calipers are different though for sure. Prolly the different # is because an older r53 has smaller lug nut holes

I finally ( sorry it took so long) got to ask Chadtoolio about this and here is his answer..........

Bingo, the lug bolt sizes....If you look at realoem.com, the rear brake rotor is the same part number for the late model R53 with the 14mm lug bolts and the R56.
