Any PMU owners out there? I'm sitting here drooling over this BBK, and it says (probably poorly translated) "when mounting, you must machine the genuine disc back plate." WTF? Anyone know what they're talking about?

Is that the rear dust cover? THe one behind the rotor?

 

I think davidv is right, I think they are talking about the rear dust cover which you need to cut out (as with most if not all BBK's).

 

oh cool, so is the dust cover easy manipulated?
