Zimmerman rotors are functionally identical to OEM parts, they just don't have the BMW logo on them. Tons of people here run them.

I'm not really sure I understand what is so special about those R1 rotors. The website is certainly pretty and has good marketing, but from a functional perspective, nothing is really jumping out at me.

Had mine changed to the Zimmerman for 1000kms now, no difference in quality or braking. As good as original factory fitted ones.
