EBC S9KF1424 Stage 9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC S9KF1424 Stage 9 Brake Kit pairs EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors into one complete, value-packed upgrade for your braking system. This kit delivers everything needed for a significant performance step up over factory brakes, bundled together for added savings versus purchasing components separately.

Yellowstuff Brake Pads:

• GG-rated high-friction compound engineered for maximum stopping power in street and spirited driving conditions
• Fully shimmed, chamfered, and slotted for optimized pad-to-rotor contact and reduced noise
• Treated with EBC's patented Brake-In™ coating for accelerated pad bed-in and faster optimal performance from the first drives
• Aramid fiber-based compound delivers superior braking performance versus OEM pads
• Performs across a wide temperature range — ideal for daily drivers, towing, hauling, and performance use

USR Sport Slotted Rotors:

• Fine slot pattern reduces wind noise — a key advantage over the S5 kit's rotor design
• Slots continuously wick away brake dust, debris, and heat for consistent pad-to-rotor contact
• Slot geometry draws in cooler air, helping rotors run significantly cooler under heavy braking
• Thermic black anti-corrosion coating provides durable rust resistance; naturally wears away in the pad-swept area after the first 10–20 stops — no removal required prior to installation
• Every rotor is fully balanced and run-out tested for a vibration-free braking experience

Kit Includes:

• EBC Yellowstuff brake pads (front and/or rear, per application)
• EBC USR sport slotted rotors
• Caliper lubricant

Installation Note: Do not install upgraded brake pads on the rear axle without also upgrading the front axle. The Thermic Black rotor coating does not need to be removed before installation — avoid using brake cleaner on the coated surface.
