What is the main benefit of the USR slotted rotors in this kit?

The USR rotors feature a fine-slotted design. This pattern helps to keep the brake pads clean by clearing away dust and gas, which ensures consistent braking performance. It also helps to reduce the wind noise often associated with more aggressive slotting patterns.

What does the EBC Brake-In coating on the pads do?

The patented Brake-In coating on the Yellowstuff pads is designed to help seat the pads to the rotors quickly and efficiently. This process ensures that you get optimal braking performance from your new setup much sooner after installation, reducing the need for a long break-in period.

Does this kit include everything needed for installation?

Yes, this EBC S9 kit is designed as a direct replacement and includes the rear Yellowstuff brake pads, the rear USR slotted rotors, and caliper lube. You should not need any additional parts for the brake components themselves, but always refer to manufacturer instructions for proper installation procedures.

About this part

Product Details

When you're looking to get the most out of your braking system, especially for spirited driving on the street or occasional track days, a complete kit like this EBC S9 Rear Brake Pad and Rotor Kit can make a significant difference. This kit is designed to fit a range of popular performance vehicles, including models like the BMW 330i, M340i, and the Toyota GR Supra, offering a substantial upgrade over stock components.

At the heart of this kit are EBC's flagship Yellowstuff GG-rated pads, known for their high friction compound that provides maximum stopping power. These pads are fully shimmed, chamfered, and feature a patented Brake-In coating to ensure they seat quickly with the rotors for immediate performance. Paired with the Yellowstuff pads are the USR (Ultra-Slot) sport rotors. These are fine-slotted rotors, which help to reduce wind noise compared to more aggressive slotting patterns, while still effectively clearing dust and gas from the pad surface for consistent braking. The rotors also feature a Geomet anti-rust coating to protect them from corrosion, especially important for vehicles that see a lot of road use.

This kit includes everything you need for a direct replacement installation, including the pads, rotors, and caliper lube. The rotors are vented, measure 345mm in diameter, and are designed to fit without requiring any modifications to your stock setup. While these are built for serious performance, it's important to note that EBC does not offer a warranty for use in racing applications.
