Power Stop K5523 Z23 Evolution Sport Carbon-Fiber Ceramic Brake Pad and Drilled & Slotted Rotor Kit

The Power Stop K5523 Z23 Evolution Sport Brake Upgrade Kit delivers a complete, bolt-on braking upgrade engineered specifically for daily-driver performance. This front-and-rear kit bundles perfectly matched components into a single box, eliminating guesswork and making installation straightforward without any modifications to your existing calipers.

Z23 Carbon-Fiber Ceramic Brake Pads

Power Stop's proprietary Z23 compound infuses carbon-fiber into a low-dust ceramic formula to strengthen the pad and provide superior, fade-free braking power. The pads are thermally scorched during manufacturing—heated to temperatures up to 700°C—to burn off any transferred surface contaminants and promote consistent long-term performance. Dual-layer rubberized shims and a chamfered, slotted pad design work together to deliver virtually silent braking operation.

Drilled & Slotted Zinc-Plated Rotors

The kit's rotors are cast from G3000 iron to strict OE tolerances and finished with a corrosion-resistant zinc plating for long-lasting protection. Precision cross-drilled holes maximize rotor cooling by dispersing heated gases and air, while rounded slots continuously wipe the pad surface clear of moisture and debris—maintaining a consistent contact patch for smooth, confident stops. Front rotor outside diameter measures 11.65 in. (296 mm) with a vented construction; rear rotor outside diameter measures 11.50 in. (292 mm) with a solid construction.

Key Features:

• Carbon-fiber ceramic Z23 compound — enhanced braking performance over standard ceramic pads with a third-party verified low-dust formula
• Thermally scorched pads — factory heat treatment for consistent, long-lasting pad performance
• Drilled & slotted zinc-plated rotors — maximum cooling, moisture evacuation, and rust/corrosion resistance
• G3000 iron rotor construction — precision cast to OE tolerances for a true bolt-on fit with stock calipers
• Dual-layer rubberized shims — chamfered and slotted pad design for virtually noise-free braking
• Front rotor diameter: 11.65 in. (296 mm), vented
• Rear rotor diameter: 11.50 in. (292 mm), solid
• Complete kit includes: front and rear rotors, Z23 carbon-fiber ceramic brake pads, premium stainless-steel hardware, and high-performance ceramic brake lubricant

Designed as a true performance upgrade over stock brakes, the K5523 reduces brake dust, eliminates noise, and improves stopping power — all in one easy, affordable package.
