Product Description

The EBC S4KF1766 Stage 4 Brake Kit combines EBC's premium Redstuff ceramic brake pads with USR sport slotted rotors to deliver significantly improved braking performance for demanding street driving. This package is engineered for drivers seeking stronger stopping power, reduced brake dust, and improved pedal feel compared to standard factory brake components.

The included Redstuff pads utilize an aramid fiber-enhanced ceramic compound that offers excellent braking response while producing substantially less dust than many performance pad alternatives. The USR slotted rotors help evacuate heat, gases, and debris from the braking surface, maintaining consistent performance during aggressive driving and repeated braking events.

Designed as a direct-fit front brake upgrade, the S4KF1766 kit installs without modification and provides a complete matched braking solution. The Geomet-coated rotors offer enhanced corrosion resistance while the pre-coated pad surfaces help accelerate the bedding-in process after installation.
