EBC Brakes S9 Yellowstuff Pad and USR Slotted Rotor Kit for 2011-2017 Audi A4, A5, and allroad (S9KF1034)

Fits select 2011-2017 Audi A4, A4 Quattro, A5, A5 Quattro, and allroad models. This EBC S9 series kit is a comprehensive braking upgrade designed for high-performance street and occasional track use, combining high-friction Yellowstuff pads with quiet-running USR slotted rotors.

The EBC Yellowstuff pads feature a flagship GG-rated friction formula that provides maximum stopping power even when cold. These pads are fully shimmed, chamfered, and slotted to minimize noise and heat buildup. They include the patented EBC Brake-In surface coating to accelerate the bedding-in process. Paired with these are the USR series sport rotors, which utilize a fine-slotted pattern to vent gas, heat, and debris while significantly reducing wind noise compared to wider-slotted alternatives. Each rotor is finished with a Geomet anti-rust coating to maintain a clean appearance and prevent corrosion on non-swept surfaces.
