The R1 Concepts drilled-and-slotted brake rotor is a black rear-left replacement for 2004–2009 Audi S4 models. This rotor serves as a replacement for the rear-left factory part on the specified S4 applications. When replacing a worn or damaged rotor, confirm axle and side details so the rotor matches the vehicle’s required fitment and restores the braking surface for that position.
