EBC S9KR1378 S9 Yellowstuff Brake Pad & USR Slotted Rotor Kit

The EBC S9KR1378 S9 Kit combines EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors in a single, convenient kit — saving approximately 15% compared to purchasing each component separately. This is EBC's top-tier street performance brake kit, engineered for drivers who demand maximum stopping power and refined on-road performance.

The Yellowstuff brake pads are EBC's highest-friction compound, carrying a GG friction rating for outstanding bite and progressive pedal feel. Each pad is fully shimmed, chamfered, and slotted to reduce noise and vibration, and features EBC's patented Brake-In coating for rapid pad bedding right out of the box — no lengthy break-in procedure required.

The USR Sport Slotted Rotors feature fine directional slots machined across the rotor face. These slots evacuate heat, gas, and debris from the pad-to-rotor contact surface while also significantly reducing wind noise compared to more aggressive drilled or wide-slotted designs — a key advantage over the S5 Kit.

Kit Includes:

• EBC Yellowstuff GG-rated high-friction brake pads (front and/or rear, per application)
• EBC USR sport fine-slotted rotors (front and/or rear, per application)
• EBC caliper lubricant for proper installation

Key Features:

• GG friction rating — EBC's highest street pad compound for maximum braking effect
• Patented Brake-In coating for fast pad seating without an extended bed-in process
• USR fine-slot rotor design reduces wind noise versus wider-slotted alternatives
• Fully shimmed, chamfered, and slotted pads minimize noise and vibration (NVH)
• Kit savings — approximately 15% less than purchasing pads and rotors separately
• Caliper lubricant included for a complete, professional installation

The EBC S9KR1378 S9 Kit is the ideal upgrade for performance-oriented street driving, delivering confident stopping power with a quieter, more refined feel than open-slot or drilled rotor alternatives.
