Product Line Details

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating to resist rust and corrosion. This full coating extends the rotor's service life and maintains a clean appearance, making it suitable for drivers who want dependable braking components that withstand environmental exposure. The 320.50030F rotor is part of this line, combining vented rotor technology with a fully coated surface and hat for balanced performance and protection.

Technical Description and Specifications

This disc brake rotor features a vented design with straight vanes that help dissipate heat generated during braking, reducing the risk of brake fade. The rotor has a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.764 inches (19.400 mm), ensuring it meets safety standards for replacement intervals. The outside diameter measures 11.024 inches (280.000 mm), and the overall height is 1.732 inches (44.000 mm). The rotor is designed with a floating disc mounting style and includes four stud/lug holes with a diameter of 0.492 inches (12.500 mm). Both the disc and hat are fully coated to protect against corrosion, and the smooth surface finish supports consistent pad contact and braking performance.

Applications and Problem Solving

• Replacement for worn or warped rotors on Hyundai Accent and Kia Rio vehicles
• Addresses rotor corrosion and rust issues with full coating protection
• Helps reduce brake fade through vented rotor design
• Restores smooth braking performance by replacing scored or uneven rotors
• Suitable for drivers seeking durable rotors with extended service life

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 0.764 inches (19.400 mm). Clean the hub surface before mounting the rotor to prevent runout. Use proper torque specifications for the 4 lug holes to secure the rotor. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. The floating disc mounting style requires careful alignment during installation to maintain proper rotor function.
