Centric 320.34099H Disc Brake Rotor - Front

Centric GCX Front Brake Rotor Overview

The Centric GCX Elemental Protection Disc Brake Rotor, part number 320.34099H, is a front vented rotor built for OE-style braking performance and corrosion resistance. It is a fitment-specific replacement for select 2007-2008 Mini Cooper front applications, including 276mm front disc setups.

For Mini Cooper owners looking for a front brake rotor with a fully coated finish and high carbon metallurgy, 320.34099H is engineered to match the vehicle’s original brake profile while helping maintain a cleaner rotor surface over time.

Key Features

• Part number 320.34099H for select Mini Cooper front brake applications
• Fully coated disc finish with coated hat for added rust and corrosion protection
• Vented rotor design with smooth surface type
• High carbon content metallurgy for OE-style rotor matching
• Outside diameter: 276 mm (10.866 in.)
• Nominal thickness: 21.9 mm; discard thickness: 20.4 mm
• 4-lug pattern with 100 mm bolt circle and 64 mm center hole
• Floating disc mounting and straight vane style

Product Line Details

Centric GCX Elemental Protection Disc Brake Rotors are built around application-specific coating patterns and rotor metallurgy. The GCX line uses Centric’s RS200 finish on non-mating surfaces to help resist rust and corrosion, while the high carbon rotor formulation is selected to align with OEM-style metallurgical requirements for the vehicle.

Detailed Description

This Centric GCX rotor is designed for front axle use on the 2007-2008 Mini Cooper, including 276mm front disc configurations and excluding JCW brake setups. The vented construction supports heat management during repeated braking, while the fully coated finish helps preserve appearance and surface protection on exposed areas. Part number 320.34099H is a direct-fit style rotor for drivers replacing worn front brake rotors on a Mini Cooper with the specified brake package.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Front brake pulsation caused by worn rotor surfaces
• Rust buildup on exposed rotor areas
• Reduced braking consistency from rotor wear
• Noise related to uneven or degraded rotor surfaces
• Replacement needs for 2007-2008 Mini Cooper front brake service

Installation Notes and Tips

Fits 2007 Mini Cooper, front, 276mm front disc; 14mm lugs; except JCW brakes. Fits 2008 Mini Cooper, front, 276mm front disc; except JCW brakes. Verify rotor diameter, lug pattern, and brake package before installation. Inspect pads, caliper condition, and hub surface during brake service to help ensure proper rotor seating and braking performance.

Quality Assurance

Centric GCX rotors are engineered to match OE performance targets and use application-specific metallurgy and coating patterns. The RS200-coated non-mating surfaces and high carbon rotor construction are intended to support long-term corrosion protection and consistent fitment for the listed Mini Cooper applications.
