EBC S9KF1080 S9 Yellowstuff Brake Pads and USR Slotted Rotor Kit

The EBC S9KF1080 is a complete brake upgrade kit that pairs EBC's flagship Yellowstuff high-friction brake pads with precision sport-slotted USR rotors and caliper lube — everything needed for a high-performance brake service in a single package. Designed for performance-minded drivers who demand maximum stopping power without sacrificing street manners, the S9 Kit offers a significant upgrade over standard brake components.

Yellowstuff Brake Pads:

• GG-rated high-friction compound for maximum brake effect from cold, without requiring warm-up for street use
• Performance improves further as heat builds — ideal for spirited street driving and track day use
• Fully shimmed, chamfered, and slotted for reduced noise and optimized pad-to-rotor contact
• Finished with EBC's patented Brake-in™ coating for rapid pad seating and reduced bed-in time
• ECE brake safety tested to perform at least as well as stock pads from cold

USR Sport Slotted Rotors:

• Fine-slot design reduces wind noise compared to more aggressively slotted rotors — a key advantage over the S5 kit
• Slots continuously wipe rotor surfaces clean, maintaining optimal pad contact and expelling heat, water, dust, and friction gases
• Cast from gray iron to EBC's exacting specifications for durability and consistent performance
• Protected with a thermic anti-rust (GEOMET) coating for long-lasting corrosion resistance — no removal required before installation
• Fully balanced and run-out tested for vibration-free, smooth braking

Kit Includes:

• Yellowstuff brake pads (GG-rated)
• USR sport slotted rotors
• Brake caliper lubricant

Installation Notes: The thermic black coating on the rotors does not need to be removed prior to installation — do not use brake cleaner or any other method to strip it, as this voids the EBC warranty. The coating will naturally wear away in the pad-swept area within the first 10–20 stops. Always upgrade front and rear brakes together when fitting performance pads.
