The R1 Concepts black drilled-and-slotted brake rotor for 2003–2008 BMW Z4 (rear right) is a vehicle-specific rotor with drilled and slotted braking surfaces and a black finish. It fits the rear-right position on those Z4 model years and serves as a like-for-like replacement rotor to restore proper rotor fit and operation at that axle.
