EBC Brakes S9KF1223 S9 Yellowstuff Brake Pad & USR Slotted Rotor Kit

The EBC S9KF1223 is a complete, high-performance brake kit that bundles EBC's flagship Yellowstuff brake pads with USR sport slotted rotors and caliper lubricant — everything needed for a full brake upgrade in one package. Purchasing as a kit delivers significant savings over buying the components individually.

The S9 kit steps up from the S5 kit with the addition of USR fine-slotted rotors, which are engineered to reduce wind noise while still delivering excellent heat, gas, and debris evacuation through their precision slot pattern.

Kit Includes:

• EBC Yellowstuff Brake Pads — GG friction-rated for maximum stopping power; fully shimmed, chamfered, and slotted to reduce noise and vibration
• Patented EBC Brake-In™ Coating — Applied to pad surfaces from the factory to accelerate bed-in and deliver optimal performance from the first stops
• USR Sport Slotted Rotors — Fine-slotted design reduces wind noise and efficiently clears brake dust, heat, water, and friction gases from the rotor surface
• Thermic Black Anti-Corrosion Coating — Protects rotor surfaces from rust; naturally wears away in the pad-swept area within the first 10–20 stops after installation
• Caliper Lubricant — Included for a complete, professional-quality installation

Installation Notes:

• Do not fit upgraded brake pads to the rear axle unless the same upgrade is also installed on the front axle
• The Thermic Black rotor coating does not need to be removed prior to installation — do not use brake cleaner or any other method to strip the coating, as this voids the EBC warranty
• All rotors are fully balanced and run-out tested for vibration-free performance

The EBC S9KF1223 is the ideal choice for performance street driving and light track use where maximum brake effect, reduced noise, and long-lasting corrosion protection are top priorities.
