EBC S9KF1066 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9KF1066 S9 Kit combines EBC's flagship Yellowstuff high-friction brake pads with sport-slotted USR rotors into a single, value-packed brake upgrade package. Engineered for spirited street driving and light track use, this complete kit delivers superior stopping power and a smooth, confident brake feel right out of the box.

The S9 Kit offers a key advantage over the EBC S5 Kit: the fine-slotted USR rotor design significantly reduces wind noise while also improving the evacuation of heat, brake dust, water, and friction gases from the braking surface. The result is consistent, fade-resistant performance even under demanding conditions.

Kit Includes:

• EBC Yellowstuff Brake Pads — GG-rated high-friction compound for maximum stopping effect; fully shimmed, chamfered, and slotted for quiet, vibration-free operation
• Patented EBC Brake-in™ Coating — Applied to pad surfaces for accelerated bed-in and optimal performance from the very first stops
• USR Sport Slotted Rotors — Fine-slot pattern reduces wind noise and efficiently clears dust, heat, and gases; features a thermic anti-rust coating for long-lasting corrosion resistance
• Caliper Lubricant — Included for proper installation

Key Features:

• GG-rated friction material for maximum brake effect
• Fine-slotted USR rotor design reduces wind noise vs. standard slotted rotors
• Thermic anti-rust rotor coating — no removal required before installation
• Fully balanced and run-out tested for smooth, vibration-free braking
• Saves approximately 15% compared to purchasing pads and rotors separately

Installation Notes: Do not fit upgraded brake pads to the rear axle without fitting the same upgrade level to the front axle. The thermic coating on the rotors does not need to be removed prior to installation — do not use brake cleaner or abrasives on the rotor surface, as this voids the EBC warranty. The coating will wear away naturally in the pad-swept area within the first 10–20 stops.
