EBC S9KR1326 Stage 9 Yellowstuff Brake Pads and USR Slotted Rotors Rear Kit

The EBC S9KR1326 is a Stage 9 rear brake kit that pairs EBC's flagship Yellowstuff high-friction brake pads with precision-engineered USR Sport Slotted rotors — delivering a significant upgrade in stopping performance over stock brakes. Buying as a kit saves over purchasing components separately.

Yellowstuff Brake Pads:

• GG-rated ultra-high friction compound for maximum brake effect
• Fully shimmed, chamfered, and slotted for quiet, smooth operation
• Finished with EBC's patented Brake-In™ coating for fast pad seating and optimum rotor mating from the first drive
• Performs across a wide temperature range — ideal for performance street driving, towing, and hauling
• Produces moderate dust levels while being gentler on rotors than most OEM pads

USR Sport Slotted Rotors:

• Manufactured from premium gray iron to EBC's exacting specifications
• Fine narrow slots efficiently expel heat, water, brake dust, and friction gases for consistent pad-to-rotor contact
• Dual slot pattern promotes even pad and rotor wear, eliminating ridges that cause brake noise
• Vented center design allows airflow between rotor faces to minimize heat buildup and warping
• Thermic anti-rust coating protects rotor surfaces — do not remove this coating with brake cleaner or any other method prior to installation
• Fully balanced and run-out tested for smooth, vibration-free braking

Kit Includes:

• EBC Yellowstuff rear brake pads
• EBC USR Sport Slotted rear rotors
• Caliper lubricant

Important Installation Notes:

• Do not fit upgrade pads to the rear of the vehicle unless the same upgrade has been fitted to the front axle
• The thermic black coating on the rotors does not need to be removed before installation — do not use brake cleaner or any other method to remove it
• EBC recommends a 500-mile break-in period with moderate braking to properly seat pads and rotors
