Product Description

The EBC S4KR1321 Stage 4 Rear Brake Kit is engineered for high-performance Chevrolet Corvette C6 applications and combines EBC's Redstuff ceramic brake pads with premium USR slotted sport rotors. This package is designed to deliver stronger braking performance, reduced brake dust, and improved thermal stability compared to many factory brake systems.

Redstuff brake pads utilize an advanced aramid fiber ceramic friction compound that provides powerful stopping performance while producing substantially less brake dust than traditional performance pad materials. The included USR rotors feature precision-machined slots that help clear away debris, moisture, and gases from the braking surface, promoting consistent pedal feel and braking response under demanding driving conditions.

The rotors are protected with EBC's GEOMET anti-corrosion coating for long-term resistance against rust and environmental exposure. Designed as a direct-fit rear brake upgrade, the S4KR1321 kit is an excellent choice for Corvette owners seeking improved street performance, enhanced brake feel, and dependable stopping power without compromising daily drivability.
