What is included in the EBC S9KF1053 kit?

This kit includes EBC Yellowstuff front brake pads, EBC USR front sport rotors, and caliper lube. It's designed as a complete front brake replacement package.

How do the USR slotted rotors differ from standard rotors?

The USR rotors feature a fine-slotted design that helps to clear dust and gas from the pad surface, improving braking consistency. This specific slot pattern is also engineered to reduce wind noise compared to coarser slot designs.

What is the EBC Brake-in coating on the pads?

The Brake-in coating is a special surface treatment on the Yellowstuff pads that helps them seat quickly and effectively against the new rotors. This process reduces the amount of time and mileage needed for proper break-in, allowing you to experience optimal performance sooner.

Product Details

This is the EBC S9 front brake kit for your 2004-2009 Audi S4. It bundles together EBC's high-performance Yellowstuff brake pads and their USR fine-slotted sport rotors, offering a significant upgrade over your stock braking components. This kit is designed to give you maximum brake effect, making it a solid choice for both spirited street driving and track use.

The Yellowstuff pads are EBC's flagship GG-rated pads, known for their high friction compound that bites hard and stops your car quickly. They come fully shimmed and chamfered, and feature a patented Brake-in coating to help seat the pads properly onto the rotors right after installation, reducing break-in time. Paired with the USR sport rotors, which have a fine-slotted design, you'll notice reduced wind noise compared to coarser slot patterns, while still benefiting from improved heat dissipation and dust clearing. The rotors also feature a Geomet anti-rust coating to protect them during storage and transit.

When you buy this kit, you're getting a direct fitment solution; no modifications are needed to install these parts on your S4. It includes the pads, rotors, and caliper lube to help you get the job done. While this kit is built for performance, please note that EBC does not offer a warranty for parts used in racing applications.
