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 rust and corrosion. This full coating covers both the braking surface and the hat area, ensuring durability and maintaining rotor integrity over time. The 320.42046F rotor is part of this line, combining corrosion resistance with vented rotor technology to support effective heat management during braking.

Technical Description and Specifications

This disc brake rotor is specifically designed for the Nissan 300ZX, featuring a vented rotor type with straight vanes that facilitate airflow and heat dissipation. The rotor’s nominal thickness is 1.028 inches (26.1 mm), with a discard thickness of 0.945 inches (24 mm), indicating when replacement is necessary to maintain safe braking performance. The rotor’s overall height measures 2.126 inches (54 mm), and it has an outside diameter of 11.024 inches (280 mm). The floating disc mounting system and smooth surface type ensure consistent pad contact and braking efficiency. The rotor includes 5 stud/lug holes with a diameter of 0.504 inches (12.8 mm) arranged on a 4.5-inch (114.3 mm) bolt circle diameter. This rotor does not include ABS tone rings or bearings.
