Raybestos Element3; Coated Rotor Product Line Details

The Element3; Coated Rotor line by Raybestos focuses on providing rotors with a protective coating that helps resist rust and corrosion, which is critical for maintaining braking efficiency over time. This coating also aids in reducing brake dust accumulation. The 980425FZN rotor features a vented design to improve heat dissipation, which helps maintain consistent braking performance under demanding conditions.

Technical Specifications and Features

This disc brake rotor has a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.764 inches (19.400 mm), indicating the minimum thickness before replacement is necessary. The rotor's outside diameter measures 12.992 inches (330.000 mm), with an inside diameter of 9.409 inches (239.000 mm). The overall height is 2.474 inches (62.850 mm), and it includes a center hole diameter of 2.638 inches (67.000 mm). The mounting bolt hole circle diameter is 4.409 inches (112.000 mm), with each mounting bolt hole diameter at 0.598 inches (15.200 mm). The rotor features a smooth surface type and a vented design to optimize heat dissipation during braking.
