EBC Brakes S9KF1109 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC Brakes S9KF1109 S9 Kit bundles EBC's flagship Yellowstuff high-friction brake pads with sport-slotted USR rotors and caliper lube into a single, cost-effective brake upgrade package — saving you money compared to purchasing each component separately.

The S9 Kit steps up from the S5 Kit by pairing the pads with USR sport slotted rotors, whose fine slot design actively reduces wind noise while simultaneously wiping the rotor surface clean for optimal pad-to-rotor contact. The slots also promote faster heat dissipation, improving braking consistency during spirited driving.

Key Features:

• GG-rated Yellowstuff brake pads — EBC's flagship high-friction compound engineered for maximum stopping power on the street and track
• Fully shimmed, chamfered, and slotted pad design for reduced noise and improved braking performance
• Patented EBC Brake-In™ coating on pads accelerates the bed-in process for fast, optimal pad seating right out of the box
• USR sport slotted rotors with fine slots that reduce wind noise, clear debris, and improve cooling
• Thermic Black anti-corrosion coating on rotors provides long-lasting rust resistance — naturally wears away in the pad-swept area within the first 10–20 stops
• Fully balanced and run-out tested for vibration-free, smooth braking performance
• Includes caliper lubricant for a complete, professional installation

Installation Notes: Do not use brake cleaner or any other solvent to remove the Thermic Black rotor coating prior to installation — this voids the EBC warranty. Always fit the same brake pad upgrade to both front and rear axles; do not install upgraded pads on the rear only.
