The PowerStop Z23 Evolution Sport Brake Upgrade Kit for 2017–2019 Audi A4 front applications provides a complete, no-modification bolt-on upgrade for daily driving. Carbon-Fiber Ceramic Z23 pads deliver a low-dust compound (about 30% less dust versus OE in tests) and mate to drilled-and-slotted rotors for better cooling. The kit includes stainless-steel hardware, multi-layer shims, high-temp ceramic lubricant, zinc-plated rotors and integral sensor wires in front pads where applicable.
