Keep rear braking smooth and balanced with the Dynamic Friction brake rotor 900-73066, a rear disc brake rotor built to bolt onto a wide range of Audi and Porsche models. It's a direct-fit replacement for applications including the 2016-2018 Audi A4, 2018-2019 and 2021-2025 Audi A5, 2014-2018 Audi A6, 2013-2025 Audi Q5, 2014-2025 Audi SQ5 and 2015-2025 Porsche Macan — see the Buyer's Guide tab for the full list of 24 applications.

• High-carbon alloy construction: engineered with premium G3000/G11H18 iron castings for strength, stability, and durability.
• Precision mill-balanced: 100% mill-balanced for smoother stopping with minimal vibration at speed.
• Geomet® coated: provides high-performance corrosion protection.
• OE vane configuration: matches the original equipment (OE) vane configuration to support proper heat dissipation.

A fine-turned finish (16 RMS) is designed to improve initial rotor and pad break-in, while Disc Thickness Variation (DTV) held to 0.010 mm maximum and lateral runout to 0.050 mm maximum help keep the surface true for even braking. As a rear-axle rotor, replace both sides together as a matched pair for balanced, consistent stops.
