EBC S9 Brake Pad and Rotor Kit

If you're looking to get the most out of your Audi S5's braking system, especially if you plan on doing some spirited driving or track days, this EBC S9 rear brake kit is a solid choice. It bundles together EBC's top-tier components to give you a significant upgrade over your stock setup. This kit is designed to be a direct replacement for your factory rear brakes, meaning no modifications are needed to install it.

At the heart of this kit are EBC's Yellowstuff GG-rated pads, known for their high friction compound that offers maximum stopping power. They're fully shimmed and chamfered for quiet operation and feature EBC's patented Brake-In coating, which helps seat the pads to the rotors quickly and efficiently, reducing the time you need to break them in. Paired with these pads are the USR fine-slotted sport rotors. These rotors are designed to reduce wind noise compared to more aggressive slotting patterns, making them a great option for a street-driven car that also sees track time. The slots help to dissipate heat and gasses, ensuring consistent performance even under heavy braking. The rotors also feature a Geomet anti-rust coating to protect them from corrosion during storage and transit.

This kit includes everything you need for the rear brakes: the pads, the USR slotted rotors, and even caliper lube to help with the installation. It's a well-built package that saves you about 15% compared to buying the parts separately. Just remember that while these are built for performance, EBC does not offer a warranty for parts used in racing applications.
