Product Details

The Power Stop K4678-26 Z26 Street Warrior Brake Upgrade Kit is a complete, bolt-on performance brake solution engineered for high-horsepower muscle cars and modified street performance vehicles. Every component needed for installation is included — rotors, pads, stainless-steel hardware, and brake lubricant — making this an easy, no-compromise upgrade over factory brakes.

Z26 Carbon-Fiber Ceramic Brake Pads

The proprietary Z26 carbon-fiber reinforced ceramic friction compound delivers superior, fade-free braking power at elevated temperatures, resisting brake fade up to 1,500°F. Brake torque is consistently higher than OEM pads, providing greater stopping confidence without sacrificing everyday street drivability. Stainless-steel shims promote superior heat dissipation for virtually noise-free operation, while the low-dust formula keeps wheels cleaner than traditional performance pads.

Drilled & Slotted Zinc-Plated Rotors

The performance rotors are cast from G3000 metallurgy to strict OE tolerances and feature precision drill holes for maximum rotor cooling during extreme operating conditions. Rounded slots continuously wipe away gas and debris, maintaining a clean, consistent contact patch on the rotor surface for safe, smooth braking. Silver Zinc Dichromate plating provides long-lasting protection against rust and corrosion while delivering an aggressive look behind open-spoke wheels.

Kit Contents & Key Features:

  • Drilled, slotted, and zinc-plated performance rotors
  • Z26 carbon-fiber ceramic brake pads with stainless-steel shims
  • Premium stainless-steel hardware and pin bushing kit
  • Ceramic brake lubricant included
  • Fade resistance up to 1,500°F
  • Low-dust, noise-free braking formula
  • G3000-grade rotor metallurgy cast to OE tolerances
  • Direct bolt-on installation — no modifications required

The Power Stop K4678-26 is the ideal upgrade for performance street drivers who demand shorter stopping distances and superior thermal stability without compromising day-to-day drivability. Verified low-dust performance through third-party on-vehicle testing.
