PowerStop AR85220XPR Disc Brake Rotor Set - Front

Front Brake Rotor Upgrade for Mustang

Power Stop AR85220XPR is a front disc brake rotor set built for 2021-2023 Ford Mustang applications. It combines drilled and slotted rotor surfaces with a zinc-plated finish to support cooler operation, cleaner pad contact, and added resistance to rust on the rotor face.

The Power Stop rotor line focuses on direct-fit performance replacements, and this front drilled, slotted, and zinc plated brake rotor pair follows that approach with OE-style fitment for the Mustang platform. This makes AR85220XPR a practical choice for drivers looking for a front brake rotor upgrade without special modifications.
