The R1 Concepts slotted brake rotor for 2008–2013 BMW 135i (rear right) is a direct-fit rear right replacement with a slotted braking surface and black finish. Intended for the listed 135i model years, it restores the brake contact area while preserving factory mounting. Replacing matched left and right rotors is recommended when correcting uneven wear to maintain balanced rear braking.
