The PowerStop Z23 Evolution Sport Brake Upgrade Kit for 2017–2018 Audi A4 front applications is a full, bolt-on brake upgrade that enhances daily driving. It combines Carbon-Fiber Ceramic Z23 pads with a low-dust compound (about 30% less dust versus OE in tests) and drilled-and-slotted rotors for improved cooling and stopping. Included are stainless-steel hardware, multi-layer shims, high-temp ceramic lubricant, zinc-plated rotors and a front sensor wire where required.
