About this part

Product Details

The EBC S9 rear brake kit for your 2004-2009 Audi S4 uses fine-slotted USR series rotors, which helps reduce wind noise compared to other slotted designs. This kit bundles EBC's flagship GG-rated Yellowstuff pads with these USR sport rotors, offering a high-friction setup designed for both street driving and track use. You'll get a significant boost in braking performance right out of the box.

The Yellowstuff pads are fully shimmed, chamfered, and slotted, and they come with EBC's patented Brake-In coating. This coating helps seat the pads quickly to the rotors, meaning you can get to maximum braking effect sooner after installation. The USR rotors themselves are vented and feature a Geomet anti-rust coating, which helps protect them from corrosion and keeps them looking good. This kit is a direct fit, meaning no modifications are needed over your stock setup.

When you buy this kit, you're getting the pads, rotors, and caliper lube all together, saving you a bit compared to purchasing them separately. Just remember that while these are built for performance, EBC does not offer a warranty if you plan to use them in racing applications.
