Detailed Product Description
This Centric GCX Elemental Protection Disc Brake Rotor features a full coating on both the disc and hat surfaces, providing superior resistance to rust and corrosion compared to uncoated rotors. The vented design with straight vanes improves airflow, helping to dissipate heat during braking and reduce the risk of brake fade. The rotor’s floating disc mounting allows for slight movement to accommodate thermal expansion, enhancing braking consistency. With a smooth surface finish, it ensures even brake pad wear and reliable stopping power. The rotor measures 10.157 inches in outside diameter and has a nominal thickness of 0.945 inches, with a discard thickness of 0.866 inches, indicating when replacement is necessary to maintain safety and performance.
The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating product line focuses on providing rotors with enhanced elemental protection through full coating technology. This coating extends rotor life by preventing corrosion and surface degradation, which is especially beneficial for vehicles exposed to harsh weather conditions or road salts. This part number 320.45058F is a precise fit for Mazda Protege models, ensuring proper alignment and mounting with its 4 lug holes and 100 mm bolt circle diameter.
