Product Description

The PowerStop K8068 Z23 Evolution Sport Brake Kit is a rear axle performance upgrade designed for select 2016-2021 Mazda 6 models. It replaces factory rear rotors and pads with drilled and slotted rotors paired with carbon-fiber ceramic brake pads to improve braking response, reduce fade, and enhance consistency during everyday driving.

The drilled and slotted rotor design improves heat dissipation and helps clear gas, dust, and moisture from the braking surface, allowing for more stable and predictable braking performance. The carbon-fiber ceramic pads are engineered for low dust output and quieter operation while providing improved stopping performance compared to standard OEM friction materials.

This kit is designed as a direct bolt-on replacement using factory calipers and mounting points, requiring no modifications. All necessary components are included for a complete rear brake refresh. Rotor size and vehicle-specific brake configuration should be verified before installation.
