EBC S9KF1189 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9KF1189 is a complete brake upgrade kit that bundles EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors and caliper lubricant — everything needed for a significant braking performance upgrade in a single package.

Compared to the EBC S5 kit, the S9 improves on noise reduction thanks to the fine-slotted USR rotor design, which minimizes wind noise while simultaneously evacuating brake dust, heat, water, and friction gases from the pad-rotor interface for consistent, fade-resistant stops.

Kit Includes:

• EBC Yellowstuff GG-rated high-friction brake pads — fully shimmed, chamfered, and slotted for maximum bite and reduced squeal
• Patented EBC Brake-In™ coating on pads for rapid bed-in and immediate optimal performance
• EBC USR (Ultimax Slotted Rotor) sport slotted brake rotors — precision-balanced and run-out tested for vibration-free braking
• Thermic Black anti-corrosion rotor coating for long-lasting rust resistance
• Caliper lubricant included

Yellowstuff Pad Features:

• GG friction rating delivers up to 30–40% more stopping power versus OEM pads
• Aramid fiber-based compound performs across a wide temperature range
• Resistant to brake fade under heavy use — ideal for performance street driving
• Medium dust level, gentler on rotors than factory pads

USR Rotor Features:

• Fine slot design reduces wind noise compared to standard slotted rotors
• Slots channel away dust, debris, and gases for a consistent pad-to-rotor contact patch
• Grey iron construction manufactured to EBC's exacting specifications
• Thermic Black coating self-removes in the pad-swept area within the first 10–20 stops — do not attempt to remove with brake cleaner

Installation Notes:

• Always fit the same pad upgrade level to both front and rear axles simultaneously
• Do not use brake cleaner on the Thermic Black rotor coating prior to installation — removal voids EBC warranty
• Rotors are fully balanced and run-out tested; verify hub mounting flange runout at installation to ensure proper function
