Centric 320.34091H Disc Brake Rotor - Rear

Centric GCX Rear Brake Rotor Overview

Centric GCX Elemental Protection Disc Brake Rotor 320.34091H is a rear vented rotor built for OE-style braking performance and long-term corrosion resistance. It is engineered for BMW applications that need a 300mm rear disc with a smooth, fully coated finish.

With a fully coated disc finish, coated hat, and high-carbon metallurgy, this rotor is built to maintain appearance and resist rust on non-mating surfaces while matching the factory brake system profile.

• Compatible with 2010-2014 BMW X1 rear brake applications and other listed BMW rear fitments

Product Details

Centric’s GCX Elemental Protection line is built around application-specific coating patterns and rotor metallurgy. This rotor uses Centric’s RS200-style protection on non-mating surfaces to help reduce rust and corrosion, while the high-carbon alloy supports consistent brake feel and OE-style thermal characteristics. The 299.8 mm outside diameter, 75 mm center hole, and floating/DIH mounting profile align with the listed BMW rear brake applications. Part number 320.34091H is also cross-referenced to Raybestos Brakes 980495FZN for the same application.

Installation Notes and Tips

Verify rotor diameter, center bore, lug pattern, and rear caliper configuration before installation. This rotor is a vented, rear application with 5 lug holes and a 120 mm bolt circle, so it should be matched to the exact BMW brake setup listed above. Clean the hub face thoroughly and inspect pads and hardware condition before completing the brake service.

Quality Assurance
