The PowerStop Z17 Semi-Coated Rotor Brake Kit for 2005–2009 Audi A4 Quattro rear brakes pairs semi-coated rotors with Z17 Evolution Plus low-dust ceramic pads and stainless-steel installation hardware. Semi-coating applies a protective silver epoxy to hats, outer edges and vanes to fight corrosion while precision mill balancing and tight tolerances minimize runout. Multi-layer shims reduce noise for a smoother, quieter commute and direct bolt-on fit.
