Product Description

The PowerStop K793 Z23 Evolution Sport Brake Kit is a front axle brake upgrade designed for select 4-lug compact sports cars, including compatible Mazda Miata applications. It replaces factory brake components with drilled and slotted rotors paired with carbon-fiber ceramic pads to improve braking performance, reduce fade, and enhance pedal consistency during everyday driving and spirited use.

The drilled and slotted rotor design helps improve cooling by allowing heat, gas, and debris to escape the braking surface more efficiently. This results in more consistent braking performance during repeated stops. The carbon-fiber ceramic pads are engineered for low dust output and quieter operation while still providing improved bite and stability compared to standard OEM pad materials.

This kit is designed as a direct bolt-on replacement using factory calipers and mounting points, making installation straightforward without modifications. It includes all necessary hardware and lubricant for a complete front brake refresh. The K793 is intended strictly for 254.7mm 4-lug front brake setups and should be verified against OE specifications before installation.
