Product Details

Centric’s GCX Elemental Protection Disc Brake Rotors are designed around vehicle-specific metallurgy and coating patterns. This rotor uses a high-carbon alloy formulation and Centric’s RS200 finish on non-mating surfaces to help protect against rust and corrosion while maintaining the look of the rotor over time. The 11.575-inch outside diameter, 2.953-inch center hole diameter, and vented construction make it a direct-fit rear rotor choice for the listed BMW Z4 applications. Part number 320.34069H is a practical option for drivers replacing worn rear rotors on a BMW Z4 and looking for an OE-style replacement with corrosion protection.

What This Rotor Helps Address

• Rear brake pulsation caused by rotor wear or uneven surfaces
• Rust buildup on exposed rotor surfaces
• Corrosion on the hat and non-mating areas
• Reduced braking consistency from worn rear rotors
• Appearance issues from untreated rotor surfaces

Installation Notes

Verify rotor dimensions, hub fitment, and brake pad condition before installation. This rotor is for rear applications only and is listed for 2003-2005 BMW Z4 rear, 2006 BMW Z4 rear with Fr 1/06 note, and 2006-2008 BMW Z4 rear. Always confirm the vehicle’s brake configuration against the fitment notes before ordering. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Centric designs the GCX line to match OE performance targets and uses application-specific coating and metallurgy selection to support consistent fitment and corrosion protection. Part number 320.34069H is part of Centric’s GCX Elemental Protection Disc Brake Rotors line for BMW Z4 rear brake service.
