Product Line Details: Centric GCX Elemental Protection Disc Brake Rotors - Full Coating

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a comprehensive protective coating that extends rotor life by minimizing corrosion. This full coating covers both the braking surface and the hat area, which helps maintain rotor integrity and appearance over time. The 320.45062F rotor is part of this line, designed specifically to meet the demands of Mazda Miata vehicles requiring solid, smooth rotors with reliable performance.

Technical Description and Specifications

This Centric rotor is a solid type with a smooth surface finish, optimized for consistent brake pad contact and heat dissipation. The floating disc mounting design allows for slight movement to reduce stress and improve braking efficiency. With a nominal thickness of 0.394 inches and a discard thickness of 0.315 inches, this rotor ensures safe operation within specified wear limits. The rotor’s outside diameter of 10.846 inches and overall height of 1.354 inches are engineered to fit Mazda Miata brake assemblies precisely. The coated finish on both the disc and hat protects against rust and corrosion, which is critical for maintaining braking performance in various driving conditions.
