The PowerStop semi-coated rear rotor for 2005–2009 Audi A4 is a partially coated, direct bolt-on replacement with painted hat and edge to reduce corrosion behind alloy wheels. Produced to match OE weight, vane count and performance, these rotors are manufactured to tight DTV and runout tolerances, feature cross-hatched surfaces for pad break-in, and are dynamically balanced and sold individually.
