EBC Brakes S9 Yellowstuff Brake Pad and USR Slotted Rotor Kit for Select Subaru 2005-2017 (S9KF1520)

Fits select 2005-2017 Subaru Impreza 2.5 GT, WRX, and WRX STI.

The EBC Brakes S9 Yellowstuff and USR Rotor Kit is a performance-focused brake upgrade designed for aggressive street and track use. By bundling EBC's flagship Yellowstuff pads with ultra-quiet USR fine-slotted rotors, this kit provides a 15% cost savings over purchasing the components separately. This direct-fit kit requires no modifications to the factory setup and includes everything needed for a complete axle refresh.

The included Yellowstuff pads are GG-rated for high friction and feature EBC’s patented Brake-In coating for rapid seating. Fully shimmed, chamfered, and slotted, these pads offer maximum stopping power with reduced vibration. They are paired with USR series sport rotors, which utilize a fine slot pattern to degas the braking surface and shed heat with significantly less wind noise than traditional slotted rotors. Each rotor is treated with a Geomet anti-rust coating to ensure long-term corrosion resistance.
