EBC S9KF1054 S9 Yellowstuff & USR Slotted Rotors Performance Brake Kit

The EBC S9KF1054 is a complete performance brake kit that bundles EBC's flagship Yellowstuff brake pads with USR sport slotted rotors and caliper lube — everything needed to upgrade your braking system in a single purchase. Compared to the S5 Kit, the S9 offers a meaningful advantage with its fine-slotted USR rotors that significantly reduce wind noise while delivering enhanced thermal management.

Yellowstuff Brake Pads:

• GG-rated high-friction compound engineered for maximum stopping power
• Fully shimmed, chamfered, and slotted for reduced noise and improved performance
• Features EBC's patented Brake-In™ coating for fast pad bed-in and immediate performance right out of the box
• Delivers up to 30–40% improved braking power compared to factory OEM pads
• Performs across a wide temperature range — ideal for daily drivers, SUVs, trucks, and muscle cars
• Maintains consistent braking without fade or fatigue under heavy use

USR Sport Slotted Rotors:

• Constructed from high-quality grey iron to EBC's precise specifications
• Fine slots wick away brake dust, debris, heat, and friction gases for a clean, consistent pad-to-rotor contact surface
• Slot design pulls in cooler air, helping rotors run significantly cooler under load
• Protected by a Black Geomet thermic anti-corrosion coating — no removal needed prior to installation; naturally wears away in the pad sweep area after the first 10–20 stops
• Every rotor is fully balanced and run-out tested for a vibration-free braking experience

Kit Includes:

• EBC Yellowstuff performance brake pads (front and/or rear as applicable)
• EBC USR sport slotted brake rotors
• Caliper lubricant

Installation Note: Do not install upgraded brake pads on the rear axle only — always upgrade both front and rear together for balanced braking performance. Do not use brake cleaner on the Geomet rotor coating, as this voids the EBC warranty.
