Centric 320.34130H Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.34130H, is a front vented rotor built for OE-style braking performance and corrosion resistance. It is engineered for BMW 528i and BMW 640i applications that call for a 330 mm front rotor with a smooth, fully coated finish.

Centric’s GCX line uses application-specific coating patterns and high-carbon metallurgy to align with the brake pad friction type and the vehicle’s original rotor profile. The result is a rotor designed for consistent fitment, clean appearance, and long-term rust protection on the non-mating surfaces.

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are part of Centric’s coated rotor family focused on OE fit and corrosion control. The GCX FC design uses coating coverage on non-mating surfaces to help preserve the rotor’s appearance and reduce rust buildup where the pad does not contact the disc. This part number 320.34130H uses a high-carbon formulation matched to the OEM-style metallurgy expected for the listed BMW front brake applications.

Detailed Description

This Centric GCX front rotor is built for 2011-2018 BMW 528i and 640i models listed in the fitment data, including BMW 528i, BMW 528i xDrive, BMW 640i Gran Coupe, BMW 640i xDrive, and BMW 640i xDrive Gran Coupe front brake applications. It measures 12.992 inches in outside diameter, 2.606 inches in overall height, and uses a vented construction with a smooth braking surface. The fully coated finish and coated hat help protect exposed areas from rust and corrosion while maintaining a clean look behind the wheel.

Part number 320.34130H is intended for drivers replacing a worn front rotor on a BMW 528i or BMW 640i platform and looking for an OE-matched rotor with application-specific coating and metallurgy.

What It Helps Address

• Brake pulsation caused by rotor wear or thickness variation
• Rust and corrosion on exposed rotor surfaces
• Reduced braking consistency from worn front rotors
• Noise or vibration associated with rotor deterioration
• Loss of OE-style braking feel on BMW 528i and BMW 640i front brake systems

Installation Notes and Tips

Verify rotor diameter, thickness, center hole, and bolt pattern against the vehicle before installation. This rotor is listed for front position use only and is not for BMW applications with a high-speed braking system where noted in the fitment data. Clean the hub mounting surface thoroughly and inspect pads, calipers, and hardware condition before completing the brake service.
