The PowerStop Z23 Evolution Sport Brake Kit for 2008–2011 Chevrolet HHR (front) combines carbon-fiber ceramic Z23 pads, drilled & slotted rotors, and stainless-steel hardware for an easy bolt-on upgrade. Z23 pads use a low-dust Carbon-Fiber Ceramic compound validated by on-vehicle third-party testing and multi-layer shims to reduce noise. Drilled and slotted rotors aid cooling and are zinc plated for corrosion protection.
