EBC S9KF1203 Yellowstuff Brake Pads and USR Slotted Rotor Kit

The EBC S9KF1203 S9 Kit pairs EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors into one complete, performance-focused brake upgrade. This kit includes everything needed for a full brake service: pads, rotors, and caliper lubricant — delivering a meaningful upgrade over stock braking components.

Compared to the EBC S5 Kit, the S9 Kit's fine-slotted USR rotors provide reduced wind noise while maintaining excellent rotor bite and heat dissipation. The angle-slotted rotor design efficiently evacuates brake dust, heat, water, and friction gases from the pad contact surface, keeping braking consistent and fade-resistant.

Yellowstuff Brake Pads:

• GG-rated high-friction compound for maximum stopping power
• Fully shimmed, chamfered, and slotted for quieter, more controlled operation
• Coated with EBC's patented Brake-in™ coating for fast, efficient pad bed-in
• Reduced brake dust compared to many high-performance compounds

USR Sport Slotted Rotors:

• Fine-slotted design reduces wind noise versus drilled alternatives
• Thermic Black anti-corrosion coating for long-lasting rust resistance
• Fully balanced and run-out tested for smooth, vibration-free braking
• Thermic Black coating naturally wears away in the pad-swept area within the first 10–20 stops — no removal required prior to installation

What's Included:

• EBC Yellowstuff brake pads
• EBC USR sport slotted rotors
• Caliper lubricant

Installation Notes: Do not install upgraded performance pads on the rear axle without also upgrading the front. Do not use brake cleaner or attempt to remove the Thermic Black rotor coating — doing so voids the EBC warranty.
