Product Details

The Power Stop KC1423 Z23 Evolution Sport Brake Upgrade Kit with Powder Coated Calipers is a complete, bolt-on braking solution engineered to deliver a meaningful performance upgrade over factory brake components. This all-inclusive kit bundles every component needed for a straightforward installation — no modifications required.

What's Included:

  • Z23 Carbon-Fiber Ceramic Brake Pads (front)
  • Drilled & Slotted Zinc-Plated Rotors (front)
  • Red Powder Coated Brake Calipers (front)
  • Premium stainless-steel installation hardware
  • High-performance brake lubricant

Z23 Carbon-Fiber Ceramic Brake Pads use a carbon-fiber-infused ceramic compound that significantly boosts stopping power compared to standard OE replacements. Each pad is thermally scorched during manufacturing to shorten break-in time and ensure consistent performance from the first stop. Dual-layer rubberized shims insulate against noise for virtually silent braking, and the low-dust formula has been validated through third-party on-vehicle testing — producing on average 30% less dust than OEM pads.

Drilled & Slotted Rotors are precision-cast from G3000 metallurgy to strict OE tolerances. Beveled precision drill holes maximize rotor cooling to prevent brake fade under demanding conditions, while rounded slots sweep away gas and debris to maintain a clear, consistent contact patch between pad and rotor. Silver Zinc Dichromate plating provides long-lasting protection against rust and corrosion.

Red Powder Coated Calipers are assembled and pressure-tested for reliability. The powder coat finish not only provides durable corrosion protection but delivers an aggressive, eye-catching appearance behind open-spoke wheels.

Key Features:

  • Carbon-fiber ceramic Z23 pad compound for superior stopping power over OE
  • Low-dust formula verified by third-party on-vehicle testing
  • Dual-layer rubberized shims for quiet, noise-free braking
  • Drilled & slotted rotors for maximum heat dissipation and fade resistance
  • Silver Zinc Dichromate rotor plating resists rust and corrosion
  • Red powder coated calipers for corrosion protection and visual appeal
  • G3000 cast iron rotors machined to strict OE tolerances
  • Complete kit — everything included for a bolt-on installation
  • No vehicle modifications required
