Product Details

Centric’s GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on corrosion resistance across the rotor’s non-friction surfaces while preserving the braking face needed for normal pad engagement. On this rotor, the fully coated disc and coated hat help protect exposed metal surfaces, and the vented construction supports heat management during repeated stops. The 320.42074F is sized at 24.0 mm nominal thickness and 22.0 mm discard thickness, with a 49.2 mm overall height and 16.5 lb weight.

This rotor is a fitment-specific replacement for front brake service on the Infiniti G35 and Nissan 350Z. Use the 320.42074F when replacing a worn or corroded front rotor on 2003-2005 Nissan 350Z front, 2003-2005 Infiniti G35 front, or 2004-2005 Infiniti G35 front applications.

What This Rotor Helps Address

• Front brake pulsation caused by rotor wear or thickness variation
• Corrosion on the rotor hat and non-friction surfaces
• Reduced braking consistency from worn front rotors
• Noise or vibration associated with damaged rotor surfaces
• Service replacement for standard brake front rotor applications

Installation Notes and Tips

Verify rotor dimensions, hub center bore, bolt pattern, and brake package before installation. This rotor is for front position use only and is listed for standard brake configurations on the covered vehicles. Inspect pads, calipers, and hub surfaces during service to help ensure even rotor contact and proper brake operation. Part number 320.42074F is intended for direct replacement on the listed Infiniti G35 and Nissan 350Z fitments.

Quality Assurance

Centric manufactures the GCX Elemental Protection rotor line with coated surfaces and application-specific sizing for consistent fitment on the listed vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
