Power Stop KC4989 Evolution Sport Brake Kit with Powder Coated Calipers - Z23

The Power Stop KC4989 Z23 Evolution Sport Brake Upgrade Kit with Powder Coated Calipers is a complete, bolt-on brake system upgrade engineered for daily-driven cars, trucks, and SUVs. This all-inclusive kit delivers everything needed for a clean, confident brake job — pads, drilled and slotted rotors, powder coated calipers, and premium stainless-steel installation hardware.

Z23 Carbon-Fiber Ceramic Brake Pads

The heart of this kit is the Z23 carbon-fiber ceramic compound — a proprietary Power Stop formula that significantly enhances braking performance over standard OEM pads. The low-dust formulation, verified through third-party on-vehicle testing, keeps wheels cleaner between washes. Dual-layer rubberized shims act as a noise insulator for virtually silent braking, while the chamfered and slotted pad design further reduces noise and promotes even wear.

Drilled & Slotted Zinc-Plated Rotors

Precision drill holes maximize rotor cooling by venting heat during aggressive or repeated braking. Slots sweep away debris and gases from the pad surface to maintain consistent bite. A Silver Zinc Dichromate plating protects the rotor surface against rust and corrosion, keeping the braking system looking sharp and performing reliably in all weather conditions.

Powder Coated Calipers

The included powder coated calipers are assembled and tested at Power Stop's Chicago, IL facility. The durable powder coat finish provides long-lasting protection against corrosion while adding a bold, eye-catching appearance behind open-spoke wheels.
