EBC S9KF1211 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9KF1211 is a complete high-performance brake kit that pairs EBC's flagship Yellowstuff brake pads with USR sport slotted rotors. This bundled kit delivers maximum stopping power for street and track use, offering a significant upgrade over standard OEM brake components.

Compared to the EBC S5 kit, the S9 kit's fine-slotted USR rotors provide reduced wind noise while simultaneously evacuating heat, water, brake dust, and friction gases from the rotor surface for consistent, fade-resistant braking.

Kit Includes:

• EBC Yellowstuff GG-rated high-friction brake pads — fully shimmed, chamfered, and slotted
• EBC USR sport slotted rotors — finished with Thermic anti-rust coating, fully balanced and run-out tested
• Caliper lubricant

Yellowstuff Pad Features:

• GG friction rating for maximum braking performance
• Patented EBC Brake-in™ coating for fast pad seating and reduced break-in time
• Shimmed, chamfered, and slotted design minimizes noise and vibration

USR Rotor Features:

• Fine slot pattern reduces wind noise compared to more aggressive slot designs
• Slots promote faster cooling and wipe the pad surface clean for optimal contact
• 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

Installation Notes:

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

EBC manufactures its brake pads in its own UK and USA factories, backing every pad with a 12-month / 10,000-mile warranty against defects in materials and workmanship.
