Product Details

The Power Stop KC4490 Z23 Evolution Sport Brake Upgrade Kit with Powder Coated Calipers is a complete, bolt-on braking solution engineered for daily drivers who demand more than stock performance. This all-inclusive kit delivers a meaningful upgrade over standard factory brakes with improved stopping power, reduced brake dust, and enhanced corrosion resistance — without the complexity of a custom build.

What's Included:

  • Front and rear Z23 Carbon-Fiber Ceramic brake pads
  • Front and rear drilled and slotted zinc-plated rotors
  • Powder coated performance calipers (assembled and tested)
  • Premium stainless-steel hardware

Key Features:

  • Z23 Carbon-Fiber Ceramic Brake Pads — Power Stop's proprietary carbon-fiber infused ceramic compound delivers enhanced braking performance over traditional ceramic pads while maintaining everyday drivability. Pads are thermally scorched from the factory for faster break-in.
  • Low-Dust Formula — The Z23 compound is verified through third-party on-vehicle testing to significantly reduce brake dust, keeping wheels cleaner between washes.
  • Drilled & Slotted Rotors — Precision drill holes allow for maximum rotor cooling and help reduce operating temperatures during demanding braking situations. Rounded slots expel gas, water, and debris to maintain a clean contact patch. Zinc plating provides long-lasting protection against rust and corrosion.
  • Powder Coated Calipers — Calipers are powder coated, assembled, and tested at Power Stop's Chicago, IL facility. The finish provides durable corrosion protection and a bold, distinctive appearance visible behind open-spoke wheels.
  • Dual-Layer Rubberized Shims — Integrated into the brake pads to reduce noise for virtually silent braking operation.
  • Complete 1-Click Kit — Everything needed for a front and rear brake system upgrade is included, making this an accessible bolt-on install for experienced DIYers or professional technicians.

The Power Stop KC4490 is purpose-built for daily-driven vehicles that occasionally demand more from their brakes, delivering a balanced combination of performance, cleanliness, and longevity in a single affordable package.
