EBC S9KR1493 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9KR1493 Stage 9 Brake Kit combines EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors into one complete, value-packed brake upgrade. This kit includes pads, rotors, and caliper lubricant — everything needed for a full brake service in a single package.

The Yellowstuff pads carry EBC's top GG friction rating, delivering 30–40% more stopping power compared to factory pads. Each pad is fully shimmed, chamfered, and slotted, and comes pre-treated with EBC's patented Brake-In™ coating for rapid pad seating and optimal performance right from the first stop. The distinctive red compound is engineered for a wide operating temperature range, resisting fade under heavy or repeated braking demands.

The USR (Ultimax Slotted Rotor) series rotors are precision-cast from grey iron and feature fine, narrow slots that continuously clean the pad surface, evacuate heat, and channel away brake dust, water, and gases. The slot design also pulls cooler ambient air across the rotor face, allowing rotor temperatures to run significantly lower than smooth-face alternatives — and reducing the wind noise common with more aggressively slotted designs. Every rotor is fully balanced and run-out tested before leaving the factory, ensuring vibration-free braking. A Thermic Black anti-corrosion coating protects the rotor surface during storage and shipping; this coating does not need to be removed before installation and will naturally wear away in the pad-swept area within the first 10–20 stops.

Kit Contents:

• EBC Yellowstuff GG-rated high-friction brake pads (shimmed, chamfered, and slotted)
• EBC USR sport slotted rotors with Thermic Black anti-corrosion coating
• Caliper lubricant

Key Features:

• GG-rated Yellowstuff compound for maximum stopping performance
• Patented EBC Brake-In™ coating for fast, easy pad bed-in
• Fine-slot USR rotor design reduces wind noise versus coarser-slotted alternatives
• Slots evacuate heat, dust, water, and gases for consistent pad-to-rotor contact
• Thermic Black anti-rust rotor coating — no removal required before install
• All rotors fully balanced and run-out tested at the factory
• Saves compared to purchasing pads and rotors separately

Installation Note: Do not fit upgraded brake pads to the rear axle unless the same upgrade level is also installed on the front axle. Do not use brake cleaner or any other chemical to remove the Thermic Black rotor coating — doing so will void the EBC warranty.
