Product Details

The Power Stop K6657-26 Z26 Street Warrior Brake Upgrade Kit is a complete rear brake upgrade engineered for high-performance, high-horsepower muscle cars and modified street vehicles. This bolt-on kit pairs proprietary Z26 Carbon-Fiber Ceramic brake pads with precision Drilled & Slotted rotors to deliver shorter stopping distances under the most demanding conditions — with no vehicle modifications required.

What's Included:

  • 2x Z26 Carbon-Fiber Ceramic Rear Brake Pads
  • 2x Drilled & Slotted Disc Rotors
  • 1x Rear Sensor Wire
  • Premium stainless-steel installation hardware and pin bushing kit

Z26 Carbon-Fiber Ceramic Brake Pads:

  • Proprietary carbon-fiber and ceramic hybrid friction compound resists brake fade up to 1,500°F
  • Delivers consistently higher brake torque than OEM pads with outstanding thermal stability
  • Low-dust formulation validated through third-party on-vehicle testing — averaging 30% less dust than OE
  • Stainless-steel shims promote heat dissipation for virtually noise-free braking performance

Drilled & Slotted Rotors:

  • Precision drill holes maximize rotor cooling to keep brake temperatures in check during extreme use
  • Rounded slots continuously wipe away gas and debris, maintaining a clear contact patch for consistent braking
  • Silver Zinc Dichromate plating guards against rust and corrosion for long-lasting performance and a clean appearance behind open wheels
  • Manufactured from G3000-grade castings and premium blanks for durability and precise fit

Key Benefits:

  • Complete kit — everything needed for a fast, easy bolt-on installation
  • Engineered for muscle cars, big wheel upgrades, and modified high-horsepower street vehicles
  • Reduced brake dust keeps wheels cleaner longer
  • Backed by a 60-Day / 36-Month / 36,000-Mile Limited Warranty

The parts I received were of high quality and met my expectations.

Easy ordering. Best price!

great parts selection and FREE SHIPPING !! Thanks

So far so good!

I had an issue with a shipping discount. I received a 30% shipping discount but the cart would not apply it.

So far good

Thanks for the parts.

Very fast, clear and secure order placement but there was a problem with the mails. My shipping address was different than my billing address. On the confirmation mail the names were changed while your website showed it correct. It was a little confusing.

It was simple.
