Product Description

The EBC S9KF1557 Stage 9 brake kit is engineered for high-performance Honda and Acura applications equipped with factory 300mm front brake systems. Combining EBC's Yellowstuff high-friction brake pads with precision-machined USR slotted rotors, this front brake package delivers significantly improved stopping power, enhanced pedal feel, and superior resistance to brake fade during spirited street driving and occasional track use.

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 utilize an advanced aramid fiber compound designed to maintain strong cold bite while remaining stable at elevated operating temperatures.

Designed as a direct-fit replacement for factory-equipped brake systems, this kit installs without modification and retains OE caliper compatibility. The Geomet-coated rotor finish also improves long-term corrosion resistance and durability, making this kit an excellent upgrade for Civic Si, RSX Type-S, and ILX performance enthusiasts seeking stronger and more consistent braking performance.
