The 760 rotors are different part numbers: 34116789543 and 34116789544

Thanks. I know the 760i/Alpina rotors are larger 374x36mm from the second post.
I pulled one of my calipers over the weekend and confirmed the 760i calipers are the same and bolt onto the 550i with the "taller" caliper carriers for the larger rotors. However I got a deal on a Stoptech BBK for my 550i and will be installing that instead. So I have the 760i calipers/carriers and the larger brake pads (new BMW OEM pads) to go with for sale if someone else wants to do this "upgrade". $350 + actuall shipping costs (~50lbs for the calipers and pads). They will need to be cleaned up (maybe painted), maybe replace seals, guide pins, rubber bushings (was my plan). You will also need the larger rotors. The larger 374x36mm 2 piece ATE (OEM) rotors were listed at
$177 each from FCP Euro. This think would be a good upgrade for a 535i/550i and a lot less than a BBK. Probably can do the whole upgrade for under $800 and some elbow grease.
