EBC S9KF1053 S9 Yellowstuff Brake Pad & USR Slotted Rotor Kit

The EBC S9KF1053 is a complete Stage 9 brake upgrade kit that pairs EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors — everything needed for a meaningful brake system upgrade in a single package. Buying as a kit saves over purchasing the components separately, and also includes caliper lubricant.

The Yellowstuff brake pads are EBC's top-tier street performance compound, carrying a GG friction rating for maximum stopping power. Each pad is fully shimmed, chamfered, and slotted, and features EBC's patented Brake-In™ coating that accelerates pad bed-in for optimal performance right out of the box.

The USR sport slotted rotors are manufactured from gray cast iron to EBC's precise specifications. Narrow precision slots channel away brake dust, dirt, and debris for a consistent pad-to-rotor contact surface. Compared to drilled rotors, the fine slot design also significantly reduces wind noise during normal driving — a key advantage of this S9 kit over the S5 kit.

What's Included:

• EBC Yellowstuff GG-rated high-friction brake pads — fully shimmed, chamfered, and slotted
• EBC USR sport slotted brake rotors
• Caliper lubricant

Key Features:

• GG friction-rated Yellowstuff compound for maximum braking performance
• Patented Brake-In™ coating for fast pad seating and reduced break-in time
• USR slotted rotors with GEOMET anti-rust coating — no removal required before installation
• Precision slots wick away dust and debris for consistent braking contact
• Fine slot design reduces brake wind noise versus drilled rotors
• Rotors are fully balanced and run-out tested for smooth, vibration-free braking
• Kit savings versus buying pads and rotors separately

Installation Note: Do not fit performance upgrade pads to the rear axle unless the same upgrade is also fitted to the front. The rotor's Thermic Black coating does not need to be removed before installation — do not use brake cleaner or any other method to remove it.
