Power Stop 05-09 Audi A4 Rear Evolution Drilled & Slotted Rotors - Pair

The rounded slots on these Power Stop Evolution rotors are designed to sweep away gasses, dust, and moisture. This helps keep a clean contact patch on the rotor surface, which is important for consistent braking, especially when you're pushing your Audi A4 hard. They're a direct bolt-on upgrade, meaning you won't need any special modifications to install them on your 2005-2009 A4, whether it's a Quattro model or not.

These rotors are precision cross-drilled to help with cooling, giving you better performance during extreme braking conditions. The drill holes are also chamfered, and the slots are rounded to help minimize stress cracking over time. Power Stop also applies a silver zinc dichromate plating to resist rust and corrosion, keeping them looking good and working well. They match the original equipment's weight and vane count, so you can expect a smooth, quiet performance without any special modifications needed.
