Product Details

Centric GCX Elemental Protection Disc Brake Rotors - Full Coating are built for front axle service on larger luxury sedans and performance-oriented passenger vehicles. This rotor uses a vented, straight-vane construction with a floating disc mounting layout, a 69.0 mm center hole diameter, and a 56.5 mm overall height. The coated disc and hat surfaces help protect the rotor from corrosion in areas exposed to moisture, road salt, and brake dust. Part number 320.51046F is a direct-fit front rotor for the listed Genesis, Hyundai, and Kia models.

Common Brake Issues This Rotor Addresses

• Brake pulsation from rotor thickness variation
• Rust buildup on exposed rotor surfaces
• Uneven braking feel from worn front rotors
• Noise caused by damaged or heat-affected rotor surfaces
• Reduced braking consistency from rotor wear near discard thickness

Installation Notes and Tips

Verify front axle fitment, bolt circle, center hole diameter, and rotor thickness before installation. Inspect pads, calipers, and hub surfaces for wear or corrosion before mounting the new rotor. Clean the hub face thoroughly so the rotor seats flat and torque wheel fasteners to the vehicle manufacturer’s specification after installation. For search reference, this rotor is commonly sought as a front brake rotor for 2012-2016 Hyundai Equus, 2015-2016 Hyundai Genesis, 2015-2017 Kia K900, and 2017 Genesis G80 applications.

Quality Assurance

Centric GCX Elemental Protection rotors are engineered with coated surfaces and application-specific dimensions to support consistent replacement fitment. Part number 320.51046F is specified for the listed front applications and follows the dimensional requirements shown above.
