Product Details

Centric GCX Elemental Protection Disc Brake Rotors are built for drivers who need a direct-fit front rotor for Mazda 3 brake service. This rotor measures 278.0 mm in outside diameter, 24.9 mm nominal thickness, and 23.0 mm discard thickness, with a 72.0 mm center hole diameter and 48.7 mm overall height. The vented construction and straight vane layout support consistent heat management during everyday braking, while the fully coated disc and coated hat help protect the rotor from rust on non-friction surfaces. If you are replacing worn front rotors on a Mazda 3 or Mazda 3 Sport, part number 320.45068F provides the correct fitment profile for the listed applications.

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on corrosion protection across the rotor’s exposed areas, making it a practical choice for routine brake maintenance in wet or road-salt environments. This rotor is a smooth-surface, floating-mount design with no ABS tone ring, no bearings included, and no miscellaneous holes.

Common Brake Issues This Rotor Can Address

• Front brake pulsation from rotor wear
• Brake noise caused by uneven rotor surfaces
• Visible rust on the rotor hat and non-friction areas
• Reduced braking consistency from a worn vented rotor
• Service replacement for a damaged or below-spec front rotor

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and wheel clearance before installation. Clean the hub mounting surface thoroughly so the rotor seats flat, and inspect pads, calipers, and hardware condition during brake service. For best results, follow the vehicle manufacturer’s brake bedding procedure after installation. Confirm front-position application only; this rotor is not listed for rear use.

Quality Assurance

Centric manufactures brake components for OE-style service applications, and this rotor is engineered to match the listed Mazda 3 and Mazda 3 Sport front fitments. Part number 320.45068F is specified for the applications shown above.
