What exactly is included in the EBC S9 rear brake kit?

This kit includes a pair of EBC USR fine slotted sport rotors and a set of EBC Yellowstuff high-friction brake pads for the rear of your vehicle. The rotors are vented, measure 315mm in diameter and 22mm thick, and have 5 bolt holes. The pad number is D2303.

How do the slotted rotors and Yellowstuff pads improve braking performance?

The USR slotted rotors help clear away brake dust and gasses, which maintains consistent stopping power and reduces noise. The Yellowstuff pads offer a high-friction compound that provides strong stopping performance while also being formulated for a comfortable pedal feel and longer pad life compared to some other performance pads.

This EBC S9 kit is described as a 'Super Fast Street And Track Kit,' indicating it's designed to perform well in both environments. However, EBC Brakes does not offer a warranty for components used in race applications.

About this part

Product Details

This EBC S9 kit gives you everything you need for the rear brakes on your 2020-2023 Cadillac CT4. You get a pair of EBC USR fine slotted sport rotors and a set of EBC Yellowstuff high-friction brake pads. This kit is designed as a direct fit, meaning no modifications are needed over your stock setup. It’s a popular choice for CT4 owners looking for an improved street and track performance upgrade.

The USR rotors are made from unique rotor alloys developed by EBC Brakes and are precision machined with a slot pattern that helps dispel gasses and debris. This slotting also contributes to quieter braking compared to more aggressive designs. They come with a Geomet anti-rust coating, offering solid corrosion resistance, and are inspected for runout to ensure they spin true. Paired with these rotors are the Yellowstuff pads, known for their softer compound that offers a longer lifetime and a more comfortable pedal feel, especially at lower speeds, while still providing high friction for confident stopping power.

This kit is specifically for the rear brakes and includes vented rotors with 5 bolt holes, measuring 315mm in diameter and 22mm thick. The FMSI pad number is D2303. While this kit is fantastic for street and track use, please note that EBC does not offer a warranty for race applications.
