Product Description

The PowerStop KC6977 is a rear Z23 Evolution Sport brake and caliper kit built for the 2015-2021 Subaru WRX, giving owners a complete rear-end braking overhaul in one box. The low-dust carbon-fiber ceramic pads pair with cross-drilled and slotted rotors for stronger, quieter stopping power validated through third-party on-vehicle testing.

The included red powder-coated calipers add corrosion resistance along with a distinctive look behind the wheels, giving WRX owners a genuine caliper-to-pad-to-rotor system upgrade rather than a partial refresh. It's a comprehensive rear brake solution for WRX owners looking to improve both stopping power and appearance in a single kit.
