Product Details

The Power Stop KC4549 Z23 Evolution Sport Brake Kit is a complete, bolt-on front brake upgrade engineered for daily drivers who demand more than stock performance. This all-inclusive kit bundles Z23 Carbon-Fiber Ceramic brake pads, drilled and slotted zinc-plated rotors, powder-coated calipers, and premium stainless-steel hardware — everything needed for a straightforward, no-guesswork installation.

Z23 Carbon-Fiber Ceramic Brake Pads

  • Carbon-fiber-infused ceramic compound delivers significantly enhanced stopping power over traditional ceramic pads
  • Low-dust, iron-free formula keeps wheels cleaner — verified through third-party on-vehicle testing
  • Thermally scorched pad surfaces accelerate break-in time for faster, consistent performance out of the box
  • Chamfered and slotted pad design ensures quiet, noise-free braking
  • Dual-layer rubberized shims provide an additional barrier against brake noise and vibration

Drilled & Slotted Zinc-Plated Rotors

  • Precision cross-drill holes maximize rotor cooling and reduce heat buildup during demanding stops
  • Rounded slots sweep away water, gas, and dust to maintain a clean contact patch between pad and rotor
  • Silver zinc plating shields rotor surfaces against rust and corrosion during everyday operation
  • Manufactured to OEM specifications for a precise, factory-correct fit

Powder-Coated Performance Calipers

  • Powder-coated finish provides long-lasting corrosion resistance and a bold, eye-catching appearance behind open wheels
  • Assembled and tested at Power Stop's Chicago, IL facility for quality assurance

What's Included

  • Front Z23 Carbon-Fiber Ceramic brake pads
  • Drilled, slotted, and zinc-plated front rotors
  • Powder-coated front calipers
  • Premium stainless-steel hardware kit
  • Ceramic-based brake lubricant

Backed by Power Stop's 24-month / 24,000-mile warranty, the KC4549 kit delivers an affordable, performance-focused brake upgrade that installs with standard hand tools and requires no modifications.
