EBC S9KF1101 S9 Yellowstuff Brake Pads & USR Slotted Rotor Kit

The EBC S9KF1101 S9 Kit combines EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors into one complete brake upgrade package — saving you up to 15% compared to purchasing the components separately. This kit includes everything needed for a front or rear axle brake service: pads, rotors, and caliper lubricant.

The Yellowstuff EDD (Extra Duty) brake pads carry a GG friction rating, delivering maximum stopping power for performance street and occasional track use. Each pad is fully shimmed, chamfered, and slotted, and features EBC's patented Brake-In coating for rapid pad seating right out of the box — eliminating the need for an extended bedding procedure.

The USR (Ultimax Slotted Rotors) feature a fine-slot pattern machined into the rotor face. Unlike drilled rotors, the slot design reduces wind noise during normal driving while still evacuating heat, gas, and debris from the pad-to-rotor contact surface for consistent, fade-resistant braking performance.

Kit Includes:

• EBC Yellowstuff GG-rated high-friction brake pads (fully shimmed, chamfered, and slotted)
• EBC Brake-In coating for fast pad seating
• EBC USR fine-slotted sport rotors
• Caliper lubricant

The S9 Kit represents an upgrade over the EBC S5 Kit by substituting the USR slotted rotors in place of plain rotors, providing improved thermal performance and reduced brake noise for drivers seeking a balanced, high-performance street brake system.
