The R1 Concepts slotted brake rotor for 2009–2016 BMW Z4 (front left) is a direct-fit left-front replacement with a slotted braking surface and black finish. Specified for the listed Z4 years, it restores the front left braking face while preserving factory mounting. When replacing a single rotor, consider the matching right-side unit to maintain balanced braking across the axle.
