EBC Brakes S9KF1173 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC Brakes S9KF1173 S9 Kit pairs EBC's flagship Yellowstuff high-friction brake pads with fine-slotted USR sport rotors into a complete, ready-to-install brake upgrade package. Purchasing this kit offers significant savings compared to buying the pads, rotors, and caliper lube individually.

Key Features:

• GG-Rated Yellowstuff Brake Pads – EBC's highest friction street pad compound, fully shimmed, chamfered, and slotted for maximum stopping power and reduced noise
• Patented EBC Brake-In™ Coating – Applied to pad surfaces at the factory for fast, efficient bed-in and optimal performance right from the start
• USR Fine-Slotted Sport Rotors – Precision fine-slot pattern continuously sweeps the pad face to clear heat, dust, water, and gases while reducing wind noise compared to standard slotted designs
• Thermic Black Anti-Corrosion Coating – Premium rotor finish 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 – Every rotor is balanced and tested at the factory to ensure vibration-free, smooth braking performance
• Kit Includes – Yellowstuff brake pads, USR slotted rotors, and caliper lubricant

Installation Notes: Do not fit upgraded pads to the rear axle unless the same upgrade is also installed on the front. Do not attempt to remove the Thermic Black coating with brake cleaner or any other chemical method, as this is not covered under the EBC warranty. The coating will self-remove in the pad contact area during the first 10–20 brake applications.

The EBC S9KF1173 is an ideal brake upgrade for performance-oriented street driving, delivering higher bite, improved fade resistance, and a quieter rotor design than standard replacement components.
