EBC Brakes S9KR1457 S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit

The EBC Brakes S9KR1457 S9 Kit bundles EBC's flagship Yellowstuff high-friction brake pads with USR sport slotted rotors and caliper lubricant into one complete brake upgrade package — saving you money over purchasing the components separately.

Compared to the EBC S5 Kit, the S9 delivers a quieter ride thanks to the fine-slotted USR rotor design, which significantly reduces wind noise at speed while simultaneously channeling away brake dust, heat, water, and friction gases for consistent stopping performance.

Yellowstuff Brake Pads:

• GG-rated friction compound — EBC's highest street/performance friction rating
• Delivers up to 30–40% more stopping power compared to standard OEM pads
• Fully shimmed, chamfered, and slotted for reduced noise and optimized pad contact
• Treated with EBC's patented Brake-In™ coating for rapid pad seating and faster bedding
• Performs across a wide temperature range — ideal for spirited street driving and heavy-use applications

USR Sport Slotted Rotors:

• Precision-machined from grey iron to EBC's exacting specifications
• Fine slot pattern reduces wind noise versus drilled or wider-slot designs
• Slots channel away heat, dust, debris, and gas buildup for consistent pad-to-rotor contact
• Slot geometry designed to draw in cooler air, helping rotors run significantly cooler under load
• Thermic Black anti-corrosion coating provides long-lasting rust resistance; naturally wears away in the pad-swept zone within the first 10–20 stops — no removal required prior to installation
• Every rotor is run-out tested for a vibration-free installation

Kit Includes:

• EBC Yellowstuff brake pads
• EBC USR sport slotted rotors
• Caliper lubricant

Installation Note: Do not install upgraded pads on the rear axle without fitting an equivalent upgrade to the front axle. Do not use brake cleaner or solvents to remove the Thermic Black coating from rotors — it will self-clear during initial break-in.
