However, the rear sport pads are only to be used in conjunction with rotor numbers 34212283387 and 34212283388, which are different than the PNs for the rear rotors on our cars. The PNs for our rear rotors are 34112283801 and 34112283802.

Do you happen to know what the difference between xxx387/388 and xxx801/802 might be?
According to my dealership they are tecnically identical to the oem rotors.
BMW want to sell some new rotors everytime one changes to the sport pads
My dealership installed the sport pads without changing the rotors, so there should not be any problems in terms of warranty as well.
The combination of new sport pads on used oem rotors works perfectly in my case, I could not be happier.
