The EBC Brakes S4 Series Brake Pad and Rotor Kit (S4KR1203) is a comprehensive performance upgrade designed for premium imports and performance sedans. This matched kit pairs EBC Redstuff ceramic pads with fine-slotted USR series rotors to deliver high-efficiency stopping power with the lowest dust output in EBC’s lineup. Designed as a direct-fit replacement, this kit bolts to factory mounting points with no modifications required.

The Redstuff pads are constructed from an Aramid fiber-ceramic compound that remains fade-resistant during spirited driving while providing silent operation. Every pad includes EBC's patented Brake-In surface coating to accelerate the bedding process. To ensure longevity, the G3000-spec sport rotors are treated with a Geomet black anti-rust coating and feature a fine-slotted design that helps expel heat, gases, and debris for consistent, parallel pad wear.
