PowerStop Z26 Street Warrior brake upgrade kit with powder-coated calipers for 2004–2007 Buick Rainier rear applications. The rear kit matches Z26 Carbon‑Fiber Ceramic pad chemistry with drilled-and-slotted rotor design to help control heat and improve stopping for heavier or higher-output street use. It ships with stainless-steel hardware and zinc-plated rotors for corrosion protection, and utilizes a low-dust pad formulation compared with OE.
