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 complete protective coating on both the disc surface and hat. This coating helps prevent rust and corrosion, extending rotor life and maintaining consistent braking performance. The full coating is particularly beneficial for vehicles exposed to harsh weather or road conditions, such as the BMW 320i, 330Ci, 330i, 330xi, and Z4 models compatible with part number 320.34052F.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to improve airflow and heat dissipation during braking. The smooth surface finish ensures optimal contact with brake pads, reducing noise and vibration. The floating disc mounting allows for slight movement to accommodate thermal expansion and reduce warping. The rotor’s dimensions, including a 12.795-inch outside diameter and 2.075-inch overall height, are engineered for precise fitment on compatible BMW vehicles.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 320i, 330Ci, 330i, 330xi, and Z4 models
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion that can degrade braking performance
• Improves heat dissipation to reduce brake fade during extended use
• Maintains consistent braking feel and pedal response

Installation Notes and Tips

Ensure the rotor is compatible with your specific BMW model and verify part number 320.34052F before installation. Clean the hub surface thoroughly to prevent runout and ensure proper rotor seating. Use appropriate torque specifications for mounting bolts and inspect brake pads for wear during rotor replacement. This rotor does not include bearings or ABS tone rings, so verify compatibility with your vehicle’s braking system.

Quality Assurance and Warranty

Centric rotors undergo rigorous quality control to meet OEM standards for fit, form, and function. The full coating provides added protection against corrosion, contributing to longer service life. Warranty information should be confirmed with the product documentation or manufacturer, as it may vary by application and region.
