Product Line Details

Centric GCX Elemental Protection rotors are application-specific, with coating patterns and metallurgy selected to align with brake pad friction type and OEM material profiles. The GCX line is engineered to provide consistent braking characteristics while helping protect non-mating surfaces from rust and corrosion. For buyers comparing Centric brake rotors, part number 320.34066H belongs to the GCX family of coated rotors built for long-term appearance and service life.

What This Rotor Helps Address

• Rust buildup on exposed rotor surfaces
• Corrosion on the hat and non-mating areas
• Brake rotor wear that calls for OE-style replacement
• Uneven appearance from uncoated replacement rotors
• Rear brake service needs on Mini Cooper vehicles

Installation Notes and Tips

Verify rotor dimensions before installation, including the 259 mm outside diameter, 64.1 mm center hole diameter, and 100 mm bolt circle. This rotor uses a solid design and is intended for rear placement on 2002-2006 Mini Cooper models. Clean the hub mounting surface before installation to help ensure proper rotor seating and brake performance.

Part number 320.34066H is listed for 2002-2006 Mini Cooper rear fitment only, so confirm vehicle year and position before ordering.

Quality Assurance

Centric designs GCX rotors to match OE performance targets and uses coated non-mating surfaces to help protect against rust and corrosion. The brand’s GCX rotor program is built around application-specific coating patterns and high carbon metallurgy for consistent fitment and material selection.
