Product Details

The Power Stop K8278 Z23 Evolution Sport Brake Upgrade Kit is a complete front and rear brake replacement solution engineered to deliver a meaningful performance upgrade over factory brake components. The kit includes everything needed for a straightforward, bolt-on installation — no modifications required.

What's Included:

  • 2x Front Drilled & Slotted Zinc-Plated Brake Rotors
  • 2x Rear Drilled & Slotted Zinc-Plated Brake Rotors
  • 1x Front Z23 Carbon-Fiber Ceramic Brake Pad Set with Hardware
  • 1x Rear Z23 Carbon-Fiber Ceramic Brake Pad Set with Hardware
  • Brake Lubricant

Z23 Carbon-Fiber Ceramic Brake Pads:

  • Carbon-fiber-infused ceramic compound strengthens pad structure and enhances stopping power over standard ceramic pads
  • Thermally scorched at up to 700°C during manufacturing to eliminate surface contaminants and improve break-in performance
  • Low-dust, iron-free formulation verified through third-party on-vehicle testing keeps wheels cleaner
  • Dual-layer rubberized shims provide a virtually silent braking experience

Drilled & Slotted Zinc-Plated Rotors:

  • Precision cross-drilled holes allow maximum heat and gas dissipation, keeping rotor temperatures down during demanding use
  • Rounded slots continuously clear moisture, debris, and brake dust to maintain consistent pad-to-rotor contact
  • Cast from G3000 metallurgy to strict OE tolerances for a perfect bolt-on fit
  • Silver Zinc Dichromate plating guards against rust and corrosion while delivering a sharp appearance behind open-spoke wheels

The Power Stop K8278 is a complete, component-matched upgrade kit designed for everyday driving. All parts are precision-engineered to work together, maximizing stopping performance and long-term durability well beyond what stock OE brakes provide.
