Product Line Details: Centric GCX Elemental Protection

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating, High Carbon Content line is designed to provide enhanced corrosion resistance and thermal performance. The full coating on both the rotor disc and hat helps protect against rust and environmental damage, while the high carbon content improves heat management during braking. This combination supports consistent braking performance and longer rotor life, making it suitable for vehicles like the BMW X3 that demand reliable stopping power under various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented with curved vanes to optimize airflow and cooling, reducing the risk of brake fade during extended use. The smooth surface finish ensures even pad contact and wear. The rotor’s overall height is 79.7 mm (3.138 inches), and it includes one miscellaneous hole for mounting or sensor purposes. It does not include an ABS tone ring or bearings, so these components must be sourced separately if required.

Applications and Problem Solving

• Replacement rotor for BMW X3 models requiring part number 320.34076H
• Addresses rotor corrosion and rust issues with full coating protection
• Improves heat dissipation to reduce brake fade during heavy braking
• Restores braking performance when original rotors are worn below discard thickness
• Suitable for vehicles experiencing uneven rotor wear or noise due to surface imperfections

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (20.4 mm) before installation
• Clean mounting surfaces and check hub for rust or debris prior to installation
• Torque lug nuts to manufacturer specifications for BMW X3
• Replace brake pads when installing new rotors to ensure optimal performance
• Verify compatibility with vehicle ABS system as this rotor does not include an ABS tone ring
