The PowerStop Z23 Evolution rear brake kit for 2002–2006 Audi A4 is a complete bolt-on upgrade with drilled & slotted rotors, carbon-fiber ceramic pads and stainless-steel hardware. The matched components are engineered to increase stopping power, reduce dust and control noise with multi-layer shims, while zinc plating or coating on rotors helps resist corrosion and maintain a clean look behind open wheels.
