The R1 Concepts drilled-and-slotted brake rotor is a black rear-right replacement for 2004–2009 Audi S4 models. It replaces a worn or damaged rear-right rotor for the listed S4 years. Verify axle and side when ordering to match the vehicle’s application and ensure the rotor fits the intended position and restores the braking surface on that corner.
