Raybestos Element3; Coated Rotor Product Line Details

The Element3; Coated Rotor line by Raybestos is designed to provide enhanced corrosion resistance and durability through a protective coating. This coating helps extend rotor life by reducing rust and wear, which is particularly beneficial for vehicles like the Ford Mustang that may be exposed to varying driving conditions. The 681938FZN rotor maintains strict manufacturing tolerances to ensure proper fit and function within the braking system.

Technical Specifications and Features

This disc brake rotor is a conventional solid type, optimized for consistent heat dissipation and braking response. The smooth surface finish supports even pad contact, reducing noise and vibration. With a nominal thickness of 0.445 inches and a discard thickness of 0.390 inches, this rotor meets OEM standards for safe replacement intervals. The five mounting bolt holes and 4.5 inch bolt circle diameter ensure compatibility with the Ford Mustang's hub assembly.
