The R1 Concepts slotted brake rotor for 2006–2013 BMW 135i (front left) is a direct-fit left-front replacement with a slotted braking face and black finish. Specified to match the original rotor position, it restores the braking surface while retaining factory mounting points. For consistent braking feel, replace the opposite front rotor when replacing a worn or damaged unit on the listed 135i models.
