The Z26 Street Warrior kit is PowerStop's answer for high-horsepower street cars, pairing Carbon-Fiber Ceramic rear pads with drilled, slotted and zinc plated rotors so the rear axle keeps its bite through repeated hard stops. Beveled drill holes vent heat off the rotor face while the rounded slots wipe gas, debris and moisture from the pad surface. Stainless-steel shims sit behind the pads to handle the higher operating temperatures a performance car generates, and third-party on-vehicle testing in Los Angeles traffic measured roughly 30% less dust than OE friction. Stainless-steel hardware, a pin bushing kit and hi-temp ceramic brake lubricant are in the box for a bolt-on install with no modifications.
