Product Details

The Power Stop K7557 Z23 Evolution Sport Brake Kit is a complete, bolt-on brake upgrade engineered for daily-driven cars, trucks, and SUVs. This all-inclusive kit pairs carbon-fiber ceramic brake pads with drilled and slotted zinc-plated rotors and premium stainless-steel hardware — everything needed for a straightforward performance brake upgrade in a single package.

Z23 Carbon-Fiber Ceramic Brake Pads

Power Stop's proprietary carbon-fiber ceramic compound significantly enhances braking performance over standard OEM pads. The iron-free, carbon-infused formula is thermally scorched during manufacturing to reduce break-in time and deliver immediate, consistent stopping power. A third-party verified low-dust formulation keeps wheels cleaner, while dual-layer rubberized shims dampen noise for virtually silent braking.

Drilled, Slotted & Zinc-Plated Rotors

The precision cross-drilled holes and machined slots work together to dissipate heat, gases, and brake dust for cooler, more consistent rotor performance under demanding conditions. The zinc plating provides long-lasting protection against rust and corrosion, maintaining a clean, aggressive appearance behind open-spoke wheels.

Kit Contents:

  • Z23 Carbon-Fiber Ceramic brake pads (front & rear)
  • Drilled, slotted & zinc-plated rotors (front & rear)
  • Premium stainless-steel hardware
  • New pin bushing kit
  • High-temp ceramic brake lubricant

Key Features:

  • Carbon-fiber ceramic formula — increased braking power with fade resistance at elevated temperatures
  • Low-dust, iron-free compound — third-party verified to keep wheels cleaner than conventional pads
  • Dual-layer rubberized shims — engineered for virtually noise-free, vibration-free braking
  • Thermally scorched pads — factory pre-bedded to shorten break-in time
  • Drilled & slotted rotors — maximum cooling and heat transfer for consistent stopping performance
  • Zinc-plated rotor finish — resists rust and corrosion for lasting durability
  • Complete bolt-on kit — all hardware included for straightforward installation
