The PowerStop Z26 Street Warrior Brake Upgrade Kit is a bolt-on front brake package built for high-horsepower muscle and modified street cars. It pairs drilled and slotted rotors with carbon-fiber ceramic Z26 pads for shorter, more consistent stops with low dust and low noise. The kit includes both front rotors, a set of Z26 pads, stainless-steel pad shims, stainless installation hardware, and high-temperature ceramic lubricant for a complete no-modification install.
