The R1 Concepts drilled-and-slotted brake rotor is a black front-left replacement for 2004–2009 Audi S4 models. Supplied for the front-left position, it replaces a worn or damaged factory rotor on the listed S4 applications. Confirm the axle and side when ordering so the rotor matches the vehicle-specific fitment and restores the proper braking surface for that position.
