EBC Brakes S9KR1478 Stage 9 Yellowstuff Brake Pad & USR Slotted Rotor Kit

The EBC Brakes S9KR1478 Stage 9 Kit pairs EBC's flagship Yellowstuff high-friction brake pads with fine-slotted USR sport rotors into one complete, cost-saving brake upgrade. Bundling pads, rotors, and caliper lube in a single kit delivers a meaningful savings over purchasing each component separately.

Compared to the EBC S5 Kit, the S9 steps up with USR series slotted rotors that significantly reduce wind noise while also channeling away brake dust, heat, water, and friction gases for consistent, fade-resistant performance.

Yellowstuff Brake Pads:

• GG-rated high-friction compound engineered for maximum stopping power
• Fully shimmed, chamfered, and slotted for reduced noise and vibration
• Patented EBC Brake-In™ coating promotes fast, even pad seating right out of the box
• Engineered to deliver up to 30–40% improved braking power compared to factory pads
• Maintains performance across a wide temperature range without fading or fatigue

USR Sport Slotted Rotors:

• Fine-slot design reduces wind noise versus drilled or plain rotors
• Slots efficiently clear dust, debris, and gases for a consistent pad-to-rotor contact patch
• Slot geometry draws in cooler air, helping rotors run up to 200°F cooler under hard use
• Thermic Black anti-corrosion coating provides long-lasting rust resistance; coating naturally wears away in the pad-swept area within the first 10–20 stops — do not remove with brake cleaner
• Every rotor is balance and run-out tested for a vibration-free braking experience

Kit Includes:

• EBC Yellowstuff brake pads
• EBC USR sport slotted rotors
• Caliper lubricant

Installation Note: Do not fit upgraded pads to the rear axle unless the same upgrade is also installed on the front axle. Manufactured in the UK and USA to EBC's strict quality control standards.
