Product Description

The EBC S9KF1657 Stage 9 Front Brake Kit delivers a substantial braking performance upgrade for 1988-1991 Honda Civic Si, Civic EX, and CRX Si models. Combining EBC Yellowstuff high-friction brake pads with precision-machined USR slotted sport rotors, this kit is engineered to improve stopping power, pedal feel, and fade resistance during aggressive street driving and occasional track use.

USR series rotors utilize narrow precision slots that help evacuate heat, brake gases, and debris while maintaining quieter operation compared to aggressive slot patterns. The included Yellowstuff brake pads feature an advanced aramid fiber compound designed for strong initial bite and stable braking under elevated temperatures. Thermic Geomet rotor coating helps protect against corrosion and keeps rotor hats and vanes cleaner over time.

This front brake package installs directly in place of factory brake components without modifications and retains compatibility with OEM-style calipers on supported 4-lug Honda applications using 242mm vented front rotors. It is an ideal solution for enthusiasts seeking reliable braking performance, improved thermal control, and enhanced driver confidence without moving to a larger brake conversion.
