Power Stop 04-09 Audi S4 Rear Z23 Evolution Sport Brake Kit

The Z23 Evolution Sport Brake Upgrade Kit from PowerStop is built around its carbon-fiber ceramic brake pads, which offer a notable step up in stopping power compared to standard ceramic pads. These pads are formulated to produce about 30% less dust than original equipment pads, helping to keep your Audi S4's wheels cleaner. The kit is designed as a direct bolt-on replacement for your stock rear brakes, meaning no modifications are needed for installation.

This kit pairs the Z23 pads with drilled and slotted rotors. The drilling helps dissipate heat, while the slots help clear away dust and gas, ensuring consistent braking performance even under harder use. Both the rotors and the included stainless-steel hardware are treated to resist rust and corrosion, making this a well-built option for your daily driver. The multi-layer rubberized shims on the pads also help to reduce noise for a smoother, quieter ride.

Everything you need for an improved rear braking setup is included in this kit, from the pads and rotors to the necessary hardware and even a high-temperature ceramic brake lubricant. It's a straightforward way to enhance your S4's braking performance and keep it looking sharp.
