EBC S9KF1113 Stage 9 Yellowstuff Brake Pads and USR Slotted Rotors Kit

The EBC S9KF1113 Stage 9 Brake Kit bundles EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors and caliper lube into one complete, cost-saving upgrade package. Designed for drivers who demand maximum stopping power, this kit delivers a significant performance step up over the standard S5 kit.

Yellowstuff Brake Pads:

• GG-rated high-friction compound engineered for maximum braking effect
• Constructed from aramid fiber materials for strength and heat resistance
• Fully shimmed, chamfered, and slotted to reduce noise and improve performance
• Features EBC's patented Brake-in™ coating for fast, efficient pad bed-in and optimal seating right from installation
• Delivers 30–40% improved braking power compared to standard factory pads
• Effective across a wide temperature range — ideal for daily drivers, trucks, and performance vehicles

USR Sport Slotted Rotors:

• Constructed from gray iron to EBC's exacting specifications
• Fine slot design reduces wind noise compared to wider-slotted rotors, making this kit quieter than the S5
• Narrow slots continuously clean the pad face and wick away dust, debris, and heat gases for consistent pad-to-rotor contact
• Slot geometry channels cooler air across the rotor surface, helping reduce operating temperatures
• Protected with a thermic black anti-corrosion coating that resists rust — naturally wears away in the pad-swept area within the first 10–20 stops
• Fully balanced and runout-tested for vibration-free braking

Kit Includes:

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

Installation Note: Do not install upgraded pads on the rear axle only — the same brake upgrade must also be applied to the front axle. The thermic black rotor coating does not require removal prior to installation and should not be cleaned with brake cleaner, as this voids the EBC warranty.
