EBC S9KR1639 S9 Yellowstuff Brake Pad and USR Rotor Kit

The EBC Brakes S9KR1639 S9 Kit combines high-performance Yellowstuff brake pads with premium USR (Ultimax Slotted Rotor) rotors for a complete front or rear brake upgrade. This matched brake system delivers enhanced stopping power, reduced brake fade, and improved pedal feel compared to standard brake components.

Yellowstuff Brake Pads:

• High-friction ceramic composite formula designed for fast street and track use
• Patented EBC Brake-In surface coating speeds the bedding process and reduces initial green fade
• Low dust formulation keeps wheels cleaner than conventional pads
• Excellent bite from cold with minimal brake warm-up required
• Temperature range ideal for performance street driving and occasional track days

USR Slotted Rotors:

• Wide aperture slots efficiently expel brake dust, gas, and debris from the pad contact surface
• Precision-balanced and run-out tested to ensure vibration-free braking
• Thermic black anti-rust coating protects non-friction surfaces from corrosion
• Direct replacement design installs with OEM hardware

This S9 Kit provides cost savings compared to purchasing pads and rotors separately, while ensuring optimal pad-to-rotor compatibility for consistent, reliable braking performance. All EBC brake components are manufactured to ISO standards and undergo rigorous quality testing.
