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 full protective coating to resist rust and corrosion. This coating extends the rotor's service life, especially in environments prone to moisture and road salt exposure. The full coating on both the disc and hat ensures consistent protection across the entire rotor surface, making it suitable for Honda Civic, CRX, and Insight vehicles requiring dependable braking components.

Technical Description and Specifications

This disc brake rotor features a vented design with straight vanes to facilitate efficient heat dissipation during braking, reducing the risk of brake fade. The rotor has a nominal thickness of 0.669 inches (17.000 mm) and a discard thickness of 0.591 inches (15.000 mm), indicating when replacement is necessary to maintain safe braking performance. The outside diameter measures 9.094 inches (231.000 mm), and the overall height is 1.732 inches (44.000 mm). The rotor mounts using a floating disc mounting system and includes four stud/lug holes with a diameter of 0.504 inches (12.800 mm). The smooth surface finish supports consistent pad contact and braking efficiency.

Applications and Problem Solving

• Replacement for worn or warped rotors on Honda Civic, CRX, and Insight
• Addresses rotor corrosion and rust issues with full coating protection
• Improves heat dissipation to reduce brake fade during extended use
• Restores braking performance affected by rotor thickness below discard limits
• Suitable for vehicles experiencing uneven braking or vibration due to rotor wear

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.669 inches (17.000 mm). Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications for the four mounting lug holes to avoid distortion. 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 requires careful alignment during installation to maintain optimal rotor performance.
