Power Stop K8439 Z23 Carbon-Fiber Ceramic Brake Pad and Drilled & Slotted Rotor Kit

The Power Stop K8439 Z23 Evolution Sport Brake Kit delivers a significant performance upgrade over stock brakes in a convenient, bolt-on package. Engineered for daily-driven vehicles, this complete front and rear kit includes everything needed for a straightforward brake system refresh — no modifications required.

The Z23 Carbon-Fiber Ceramic brake pads are formulated with a proprietary carbon-fiber compound that delivers stronger stopping power compared to traditional ceramic pads. A low-dust formula — validated through third-party on-vehicle testing — produces on average 30% less brake dust versus OE pads, helping keep wheels cleaner between washes.

The drilled and slotted rotors are precision-cast from G3000 metallurgy to strict OEM tolerances. Drill holes promote maximum rotor cooling to manage heat during demanding stops, while rounded slots continuously wipe away gas and debris to maintain a clean, consistent contact patch for smooth, fade-resistant braking. Silver Zinc Dichromate plating provides a polished appearance and defends against rust and corrosion.
