Product Line Details: Centric GCX Elemental Protection Rotors

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating, High Carbon Content line focuses on providing rotors with enhanced elemental protection through a full coating process. This coating covers both the disc and hat surfaces, reducing the risk of rust and corrosion over time. The high carbon content in the rotor material improves wear resistance and thermal stability, making these rotors suitable for vehicles like the Smart Crossblade, Fortwo, and Roadster that require consistent braking performance under varied driving conditions.

Technical Specifications and Features

This rotor features a solid disc design with a smooth surface type, ensuring consistent contact with brake pads. The floating disc mounting system helps manage heat buildup during braking, which can improve rotor longevity. The rotor measures 11.012 inches in outside diameter and has a nominal thickness of 0.374 inches, with a discard thickness of 0.315 inches, indicating when replacement is necessary. The mounting bolt hole circle diameter is 4.409 inches with three lug holes sized at 0.5 inches diameter, designed to fit the specified Smart models precisely.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Smart Crossblade, Fortwo, and Roadster
• Addresses rotor corrosion and rust issues due to full coating
• Improves braking consistency by maintaining smooth rotor surface
• Helps reduce brake noise and vibration caused by uneven rotor wear
• Suitable for vehicles experiencing heat-related rotor degradation

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.315 inches before installation. Clean the hub surface to prevent uneven rotor mounting. Use proper torque specifications for the 3 lug bolts to secure the rotor. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s braking system. The floating disc mounting requires correct alignment to function properly.
