Detailed Product Description

The AR85210EVC rotor is constructed as a full cast, solid disc brake rotor designed specifically for the rear brakes of the Ford Mustang Mach-E. Its nominal thickness of 11.2 mm ensures adequate material for effective heat dissipation and braking performance, while the discard thickness of 9.0 mm indicates when the rotor should be replaced to maintain safety standards. The rotor’s smooth surface finish supports consistent pad contact and braking efficiency. With an outside diameter of 316.0 mm and an overall height of 32.2 mm, this rotor matches OEM specifications for proper fitment and function. The Geomet coating provides a protective layer against rust and corrosion, which is especially beneficial in environments prone to moisture and road salt exposure.

Common Applications and Problem Solving
