Product Description

The EBC S9KF1520 Stage 9 brake kit is engineered for Subaru WRX STI and Brembo-equipped turbo Subaru models requiring improved braking performance for aggressive street use and occasional track driving. Combining EBC's Yellowstuff high-friction brake pads with precision-machined USR slotted rotors, this front brake package delivers stronger stopping power, improved pedal feel, and superior resistance to brake fade under repeated hard braking conditions.

The included USR sport rotors feature a narrow-slot design that efficiently evacuates heat, gases, water, and brake dust while reducing the wind noise commonly associated with aggressive slotted rotors. Yellowstuff pads use an advanced aramid fiber compound that provides excellent cold bite for street driving while maintaining stable braking performance at elevated temperatures.

Designed as a direct-fit replacement for factory Brembo-equipped applications, this kit installs without modification and retains OE caliper compatibility. The Geomet-coated rotor finish also improves corrosion resistance and long-term durability, making this kit an excellent upgrade for performance-focused Subaru owners.
