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 on both the disc surface and the hat. This full coating helps prevent rust and corrosion, extending the rotor's service life and maintaining consistent braking performance. The vented design with straight vanes enhances cooling efficiency, which is critical for vehicles like the Acura Civic, Honda CR-Z, and RSX that demand reliable stopping power under various driving conditions.

Technical Specifications and Features

This disc brake rotor features a smooth surface type and a vented rotor design with straight vanes to optimize heat dissipation during braking. The rotor has a nominal thickness of 0.827 inches (21.000 mm) and a discard thickness of 0.748 inches (19.000 mm), ensuring it meets safety standards for replacement. The overall height measures 1.850 inches (47.000 mm), and the outside diameter is 10.295 inches (261.500 mm). The rotor mounts using a floating disc mounting system and fits vehicles with a 5-lug pattern, 0.496 inch (12.600 mm) stud diameter, and a mounting bolt hole circle diameter of 4.500 inches (114.300 mm). The hat ID is 5.512 inches (140.000 mm) with four miscellaneous holes for proper fitment.

Applications and Problem Solving

• Replacement for worn or warped rotors on Acura Civic, Honda CR-Z, and RSX models
• Addresses rotor corrosion and rust issues with full coating protection
• Improves heat dissipation to reduce brake fade during extended use
• Restores smooth braking performance by replacing damaged or uneven rotors
• Compatible with vehicles requiring vented rotors for enhanced cooling

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.748 inches (19.000 mm) before installation. Clean the hub surface thoroughly to prevent uneven rotor mounting. Use proper torque specifications for the 5 lug nuts with 0.496 inch (12.600 mm) diameter studs. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s braking system. The floating disc mounting design allows for slight movement to reduce stress and improve rotor lifespan.
