Product Line Details: Centric GCX Elemental Protection

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating, High Carbon Content line focuses on providing rotors with a fully coated surface and high carbon steel composition. This combination helps protect against rust and corrosion while maintaining structural integrity under demanding braking conditions. The full coating extends to both the disc and hat surfaces, ensuring comprehensive protection for the rotor assembly.

Technical Specifications and Features

This rotor features a nominal thickness of 0.862 inches (21.9 mm) and a discard thickness of 0.803 inches (20.4 mm), ensuring a precise fit and long service life. The overall height measures 1.780 inches (45.2 mm), with a center hole diameter of 2.520 inches (64 mm) and a mounting bolt hole circle diameter of 100 mm (3.937 inches). It includes four stud/lug holes with a diameter of 0.630 inches (16 mm). The rotor is vented with pillar-style vanes to optimize airflow and cooling during braking. The smooth surface finish supports consistent pad contact and braking performance. Weighing approximately 17.2 lbs (7.82 kg), this rotor balances durability and weight for the Mini Cooper application.

Compatible Vehicles and Applications

• Designed specifically for Mini Cooper models requiring part number 320.34114H
• Ideal for replacing worn or damaged front or rear disc brake rotors
• Addresses issues such as rotor warping, excessive brake noise, and reduced braking efficiency
• Suitable for vehicles experiencing corrosion or surface rust on original rotors
• Helps restore smooth braking and pedal feel in Mini Cooper brake systems

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 0.803 inches (20.4 mm). The floating disc mounting design requires proper alignment during installation to avoid uneven wear. Use appropriate torque specifications for the four lug holes (16 mm diameter) and verify the mounting bolt hole circle diameter of 100 mm (3.937 inches) matches the vehicle hub. This rotor does not include bearings or an ABS tone ring, so verify compatibility with your vehicle’s braking system components.
