Product Details

Centric’s GCX line focuses on matching OE performance while adding full-surface protection on non-mating areas. This rotor uses Centric’s RS200 finish to help preserve appearance and reduce corrosion on the hat and outer surfaces, while the friction faces remain ready for braking contact. The GCX Elemental Protection Disc Brake Rotors - Full Coating, High Carbon Content line also uses application-specific coating patterns and rotor metallurgy choices to align with the vehicle’s original brake profile.

Part number 320.34141H is a rear vented rotor for select BMW models including 2012 BMW 335i, 2013-2015 BMW 335i and 335i xDrive, 2014-2016 BMW 428i and 435i variants, 2016-2020 BMW 330i, 340i, 430i, and 440i applications, plus Gran Coupe and xDrive versions with the listed rear 330 mm brake setup. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Rear brake pulsation caused by worn or heat-cycled rotors
• Corrosion on exposed rotor surfaces and hat areas
• Brake noise related to uneven rotor wear
• Reduced braking consistency from rotor thickness loss
• Replacement needs for BMW rear 330 mm brake service

Installation Notes and Tips

Verify rear axle fitment by year, model, brake package, and caliper type before ordering. This rotor is listed for rear use only and is not for vehicles outside the specified BMW applications. Confirm the 330 mm rear disc specification, M Sport or base brake notes, and plain or single-piston caliper requirements shown in the fitment data. Inspect pads, calipers, and mounting surfaces during service to help ensure even rotor contact.
