Product Line Details: Centric GCX Elemental Protection

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating to reduce rust and corrosion. This full coating extends the rotor's service life and helps maintain consistent braking performance, especially in environments prone to moisture and road salt. The 320.42026F rotor benefits from this coating on both the disc and hat surfaces, ensuring comprehensive elemental protection.

Technical Specifications and Features

This disc brake rotor features a solid design with a smooth surface type, optimized for consistent pad contact and braking efficiency. The nominal thickness of 0.394 inches (10.000 mm) ensures durability, while the discard thickness of 0.354 inches (9.000 mm) indicates the minimum safe thickness before replacement is necessary. The rotor measures 11.417 inches (290.000 mm) in outside diameter and has an overall height of 1.850 inches (47.000 mm). It includes a floating disc mounting system and 5 stud/lug holes with a diameter of 0.502 inches (12.750 mm), matching the mounting bolt hole circle diameter of 4.500 inches (114.300 mm). The center hole diameter is 2.681 inches (68.100 mm), and the rotor weighs approximately 10.75 lbs (4.89 kgs).

Applications and Problem Solving

• Replacement rotor for Nissan 200SX and 300ZX models requiring corrosion-resistant braking components
• Addresses rotor surface rust and corrosion issues common in humid or salted road environments
• Helps restore smooth braking performance by providing a smooth, fully coated rotor surface
• Suitable for vehicles experiencing rotor wear near discard thickness limits
• Ideal for solid rotor applications where vented rotors are not specified

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.394 inches. Clean the hub surface and mounting area to prevent uneven rotor seating. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s braking system. Use proper torque specifications for the 5 lug nuts to secure the rotor firmly. The floating disc mounting design requires careful alignment during installation to avoid rotor runout.

Quality Assurance and Warranty

Centric brake rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The full coating on the disc and hat surfaces provides added protection against corrosion, contributing to longer service life. While specific warranty details are not provided here, Centric typically offers coverage against defects in materials and workmanship. Always consult product documentation or the manufacturer for exact warranty terms.
