Hi Guys,
Im getting around to installing the rear M5 brakes on my 550. What I noticed is that the rotor set screw hole on the M5 rear rotor is about a 1/2 inch off as compared to the OEM 550 rear rotor.

To me, it looks like the M5 rear rotor set screw hole will not line up with the rear hub.

Any thoughts?

thanks!

 

C'mon guys. There are some really knowledgable people here...

 

Here is a pic of the M5 rear rotor and 550i rear rotor. Take a look at the location of the set screw holes.
