EBC Brakes S9KF1229 S9 Yellowstuff Brake Pad and USR Sport Slotted Rotor Kit

The EBC S9KF1229 is a complete front brake upgrade kit combining EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors and caliper lube — everything needed for a high-performance brake service in a single package.

The S9 kit delivers a meaningful performance advantage over the S5 kit, thanks to the fine-slotted USR rotor design that significantly reduces wind noise while simultaneously channeling away brake dust, heat, water, and friction gases for consistent, fade-resistant stopping power.

Kit Includes:

• EBC Yellowstuff GG-rated high-friction brake pads — fully shimmed, chamfered, and slotted
• Patented EBC Brake-In™ coating on pads for fast bed-in and optimal initial bite
• USR sport slotted rotors constructed from gray iron with a Thermic Black anti-corrosion coating
• Rotors are fully balanced and run-out tested for vibration-free braking
• Caliper lubricant included

Rotor Specifications:

• Design: Vented, sport slotted
• Diameter: 300mm
• Thickness: 25mm
• Height: 49mm
• Center Hole Diameter: 63.5mm
• Bolt Holes: 5
• FMSI Pad No.: D1044

Installation Notes:

• The Thermic Black rotor coating does not need to be removed prior to installation — it will naturally wear away in the pad-swept area within the first 10–20 stops
• Do not use brake cleaner or any other method to remove the Thermic Black coating, as this is not covered under EBC warranty
• Do not fit upgraded pads to the rear axle unless the same upgrade is also installed on the front

Manufactured in EBC's own UK and USA facilities, the S9KF1229 is a bolt-on performance brake solution offering a cost savings compared to purchasing the pads, rotors, and lube individually.
