EBC Brakes S9KR1273 Stage 9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9KR1273 Stage 9 Brake Kit pairs EBC's flagship Yellowstuff high-friction brake pads with fine-slotted USR sport rotors into one complete, cost-saving brake upgrade package. The kit includes brake pads, rotors, and caliper lubricant — everything needed for a full brake service in a single purchase.

Yellowstuff Brake Pads:

• GG-rated high-friction compound engineered for maximum stopping power across a wide temperature range
• Fully shimmed, chamfered, and slotted for reduced noise and optimized pad-to-rotor contact
• Features EBC's patented Brake-In™ coating for fast pad seating and shorter break-in periods
• Performs well for spirited street driving and vehicles requiring more aggressive stopping capability than stock pads provide

USR Sport Slotted Rotors:

• Constructed from gray iron to EBC's exacting specifications
• Fine-slotted design reduces wind noise compared to the S5 kit's rotors while efficiently wiping the pad surface clean for consistent contact
• Narrow slots continuously evacuate brake dust, heat, water, and friction gases from the pad/rotor interface
• Protected by a Thermic Black anti-corrosion coating — no removal required prior to installation; coating naturally wears away in the pad-swept area within the first 10–20 stops
• Fully balanced and runout-tested for smooth, vibration-free braking

Installation Notes:

• Do not install upgraded pads on the rear axle unless the same upgrade is also fitted to the front
• Do not use brake cleaner or any other chemical to remove the Thermic Black rotor coating — doing so voids the EBC warranty

The EBC S9 kit delivers a meaningful braking upgrade over stock components and represents a better value than purchasing Yellowstuff pads and USR rotors separately.
