EBC Brakes S9KF1243 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC Brakes S9KF1243 S9 Kit combines EBC's flagship Yellowstuff high-friction brake pads with fine-slotted USR sport rotors into a single, value-packed brake upgrade kit. This kit includes everything needed for a complete brake service — pads, rotors, and caliper lubricant — delivering significant savings over purchasing components individually.

The S9 Kit steps up from the S5 Kit with the addition of USR sport slotted rotors, whose fine slot pattern reduces wind noise while efficiently evacuating brake dust, heat, water, and friction gases from the rotor surface for consistent, fade-resistant braking performance.

Kit Includes:

• EBC Yellowstuff Brake Pads — GG-rated, ultra-high-friction compound engineered for maximum stopping power in both street and track applications
• Pads are fully shimmed, chamfered, and slotted to minimize noise and vibration
• Patented EBC Brake-In™ coating pre-applied to pad surface for rapid bed-in and optimal performance from the first stop
• EBC USR Sport Slotted Rotors — fine slot pattern reduces wind noise and clears debris from the braking surface
• Rotors feature a Thermic Black anti-corrosion coating for long-lasting rust resistance; no removal required prior to installation
• Rotors are fully balanced and run-out tested for vibration-free braking
• Caliper lubricant included for complete installation

Installation Notes: The Thermic Black rotor coating will naturally wear away in the pad-swept area within the first 10–20 stops after installation. Do not attempt to remove the coating with brake cleaner or any other method, as this is not covered under the EBC warranty. Always fit matching upgraded pads to both axles — do not install performance pads on the rear only.

Manufactured in EBC's UK and USA facilities, the S9KF1243 kit is backed by EBC's commitment to quality control and performance testing, making it an ideal choice for drivers seeking a high-performance street and light-track brake upgrade.
