EBC S9KF1215 S9 Yellowstuff Brake Pad & USR Slotted Rotor Kit

The EBC S9KF1215 is a complete brake upgrade kit that bundles EBC's flagship Yellowstuff high-friction pads with USR sport slotted rotors and caliper lubricant — delivering a significant performance step up over standard OEM braking systems.

Compared to the EBC S5 Kit, the S9 offers an advantage in reduced wind noise, thanks to the fine-slot design of the USR series rotors. The narrow slots also help wick away brake dust, dirt, and debris for a more consistent pad-to-rotor contact surface, and are engineered to draw in cooler air to help keep rotor operating temperatures down.

Kit Includes:

• EBC Yellowstuff Brake Pads — GG-rated, high-friction aramid fiber compound pads designed for maximum stopping power; fully shimmed, chamfered, and slotted to reduce noise and improve bite
• Patented EBC Brake-In™ Coating — Applied to pad surfaces from the factory to accelerate the bed-in process and promote fast, even pad seating right out of the box
• EBC USR Sport Slotted Rotors — Precision-machined grey iron rotors featuring a fine slot pattern for improved dust and gas evacuation; finished with a thermic black anti-corrosion coating that wears away naturally in the pad-swept area during the first 10–20 stops
• Caliper Lubricant — Included to ensure smooth caliper operation during and after installation

Yellowstuff Pad Highlights:

• GG friction rating for maximum braking performance
• Delivers up to 30–40% improved braking force compared to factory pads
• Effective across a wide temperature range — suitable for spirited street driving and demanding daily use
• Resists brake fade during heavy or repeated brake applications
• Produces moderate dust levels that are gentler on rotors than many OEM compounds

USR Rotor Highlights:

• Fine slot pattern reduces wind noise versus non-slotted designs
• Slots channel away heat, water, and friction gases for consistent pad contact
• Thermic black anti-rust coating provides corrosion protection — no removal required prior to installation
• Do not apply brake cleaner to the coating, as this may void the EBC warranty

Installation Notes:

• Always upgrade both front and rear brake pads at the same time — do not fit performance pads to the rear only
• Check and confirm rotor runout at installation to avoid vibration during the break-in period
• The thermic coating will naturally wear away in the pad contact area within the first 10–20 brake applications

The EBC S9KF1215 kit is an excellent choice for drivers seeking a meaningful brake system upgrade with a high-friction pad compound and slotted rotors in a single, cost-effective package.
