Product Description

The PowerStop KC103 Z23 Evolution Sport rear brake kit is designed for 2003-2005 Infiniti G35 and Nissan 350Z applications equipped with the specified factory brake configuration. The complete package combines cross-drilled and slotted rear rotors, carbon-fiber ceramic brake pads, and a red powder-coated replacement caliper to provide a performance-focused upgrade for street-driven vehicles.

The Z23 carbon-fiber ceramic pads are engineered to deliver strong braking performance with reduced dust and noise, while the drilled and slotted rotors help manage heat and remove brake debris from the friction surface. The zinc-plated rotor finish adds corrosion resistance, and the powder-coated caliper provides additional protection against environmental exposure.

KC103 is designed as a direct bolt-on brake upgrade using the compatible factory mounting configuration. The kit includes the rear rotor-and-pad package, replacement caliper, stainless-steel installation hardware, and high-temperature ceramic lubricant. Verify the vehicle's exact brake configuration before installation, particularly on G35 and 350Z models with different factory brake combinations.
