EBC Brakes S9KF1261 Stage 9 Brake Kit Yellowstuff Pads and USR Slotted Rotors

The EBC Brakes S9KF1261 Stage 9 Brake Kit bundles EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors and caliper lube into one complete, value-packed upgrade. Purchasing as a kit delivers meaningful savings over buying the pads and rotors separately, making it an efficient choice for drivers seeking maximum braking performance.

The Yellowstuff brake pads carry EBC's top GG friction rating, delivering exceptional stopping power across a wide operating temperature range. Each pad is fully shimmed, chamfered, and slotted to minimize noise and vibration. All Yellowstuff pads feature EBC's patented Brake-In™ coating, which accelerates the bed-in process so pads reach optimal performance faster after installation.

The USR sport slotted rotors are precision-machined from gray iron to EBC's exacting standards. The fine slot pattern vents heat, water, and brake gases from the pad surface while also reducing the wind noise commonly associated with plain rotors—a key advantage over the S5 kit. Rotors are treated with a thermic anti-corrosion coating that protects against rust during storage and shipping; this coating naturally wears away in the pad-swept area within the first 10–20 stops and does not need to be removed prior to installation.

Kit Includes:

• EBC Yellowstuff GG-rated high-friction brake pads — shimmed, chamfered, and slotted with Brake-In™ coating
• USR sport slotted rotors — gray iron construction with thermic anti-corrosion coating
• Caliper lubricant

Key Features:

• GG friction rating for maximum stopping power
• Fine slot pattern reduces wind noise versus plain-face rotors
• Patented Brake-In™ coating for fast pad seating
• Thermic anti-rust rotor coating for long-lasting corrosion resistance
• Fully balanced and run-out tested for vibration-free braking
• Complete kit — no additional components required

Installation Note: Do not fit upgraded brake pads to the rear axle only — if upgrading the rear, the front must also be upgraded. Do not use brake cleaner or any other solvent to remove the thermic rotor coating, as doing so voids the EBC warranty.
