EBC Brakes S9KR1201 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9 Kit combines EBC's flagship Yellowstuff high-friction brake pads with fine-slotted USR sport rotors and caliper lubricant into one complete, value-packed brake upgrade. Compared to the EBC S5 Kit, the S9 delivers a notable advantage in reduced wind noise thanks to the precision fine-slot pattern of the USR series rotors.

The Yellowstuff brake pads carry EBC's top GG friction rating, engineered for maximum stopping power in demanding street and track conditions. Each pad is fully shimmed, chamfered, and slotted to minimize noise and vibration, and features EBC's patented Brake-In™ coating for rapid pad seating right out of the box — no extended break-in period required.

The USR sport slotted rotors are precision-machined with fine angle slots that continuously clean and refresh the pad surface, promoting efficient evacuation of heat, brake dust, water, and friction gases. Rotors are treated with a Thermic Black anti-corrosion coating for long-lasting rust resistance. The coating does not need to be removed before installation — it 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 (fully shimmed, chamfered, and slotted)
• EBC USR sport slotted rotors with Thermic Black anti-corrosion coating
• Caliper lubricant

Key Features:

• GG friction rating for maximum brake effect on street and track
• Patented Brake-In™ coating for fast pad seating and immediate performance
• Fine-slotted USR rotors reduce wind noise compared to standard slotted designs
• Angle-cut slots evacuate heat, water, dust, and gases from the braking surface
• Thermic Black anti-rust rotor coating for extended service life
• All components fully balanced and run-out tested for vibration-free braking
• Bundle savings versus 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 chemical to remove the Thermic Black coating — doing so voids the EBC warranty.
