Product Details

The Power Stop KC4659 Z23 Evolution Sport Brake Upgrade Kit with Powder Coated Calipers is a complete, bolt-on brake solution engineered for daily drivers who demand more than factory-grade stopping power. This all-inclusive kit bundles carbon-fiber ceramic brake pads, drilled and slotted rotors, powder coated calipers, and premium stainless-steel hardware — everything needed for a straightforward upgrade in a single box.

Key Features:

  • Z23 Carbon-Fiber Ceramic Brake Pads — Infused with carbon fiber, these pads deliver increased braking performance over standard ceramic pads while maintaining everyday drivability. The low-dust formula is verified through third-party on-vehicle testing, keeping wheels cleaner longer.
  • Dual-Layer Rubberized Shims — Engineered to insulate vibration and noise for virtually silent braking operation.
  • Drilled & Slotted Zinc-Plated Rotors — Precision drill holes and slots promote maximum rotor cooling, dispel heat and gases under hard braking, and provide long-lasting protection against rust and corrosion.
  • Powder Coated Calipers — Assembled and tested for a quality fit, the powder coat finish resists corrosion while delivering a bold, eye-catching appearance behind open wheels.
  • Premium Stainless-Steel Hardware Included — All necessary mounting hardware and ceramic brake lubricant are included for a complete, hassle-free installation.
  • Thermally Scorched Pads — Factory heat-treating burns off surface contaminants and shortens the break-in period, so pads are ready to perform sooner.

The Z23 kit is designed as a direct bolt-on replacement, engineered to match original equipment specifications for a precise fit. Whether refreshing worn-out factory brakes or stepping up from stock performance, the KC4659 delivers a noticeable improvement in stopping confidence, cleaner wheels, and a more aggressive look — all in one affordable upgrade.
