EBC S9KF1028 Stage 9 Yellowstuff Brake Pad & USR Slotted Rotor Kit

The EBC Stage 9 (S9KF1028) is a premium front brake kit that bundles EBC's flagship Yellowstuff high-friction brake pads with USR sport-slotted rotors and caliper lube — giving you everything needed for a serious brake upgrade in a single, cost-effective package.

Compared to the S5 kit, the S9 steps up to fine-slotted USR series rotors, which are engineered to reduce wind noise while simultaneously improving brake dust, heat, and debris evacuation for more consistent pad-to-rotor contact.

Yellowstuff Brake Pads:

• GG friction-rated compound — EBC's highest street-performance pad rating
• Delivers up to 30–40% improved braking power compared to factory pads
• Aramid fiber-based compound engineered for wide temperature range performance
• Fully shimmed, chamfered, and slotted to reduce noise and improve bite
• Coated with EBC's patented Brake-In™ coating for rapid pad bed-in and fast initial seating
• Produces medium brake dust levels — significantly less abrasive to rotors than OEM pads
• Maintains consistent braking performance under heavy use without fade or fatigue

USR Sport-Slotted Rotors:

• Constructed from high-grade G3000 gray iron to EBC's exacting quality standards
• Fine slots wick away dust, dirt, debris, and friction gases for a clean, consistent contact surface
• Slot geometry is designed to draw in cooler air, helping rotors run significantly cooler under load
• Protected by a GEOMET anti-rust coating for long-lasting corrosion resistance and a clean appearance
• Fully balanced and run-out tested at the factory for smooth, vibration-free braking

Kit Includes:

• EBC Yellowstuff front brake pads
• EBC USR sport-slotted front rotors
• EBC caliper lubricant

Installation Note: The GEOMET thermic black coating on the rotors does not need to be removed prior to installation — do not use brake cleaner on the coating. It will naturally wear away in the pad-swept area after the first 10–20 stops. Always upgrade pads and rotors on both axle ends simultaneously for balanced braking performance.
