For BMW Z4 rear brake service, this rotor set uses an 11.60-inch outside diameter, 17.40 mm nominal thickness, 17.40 mm discard thickness, and 3.00-inch overall height. The vented design and slotted X drilled surface support consistent friction contact, while the zinc-plated finish helps protect the rotor in everyday driving conditions.\u003c\/p\u003e\u003cp\u003eThis part cross-references Raybestos Brakes 980393 for the same application.
