Product Details

Centric’s GCX Elemental Protection Disc Brake Rotors - Full Coating line is built around corrosion-resistant surface treatment for drivers who want a cleaner-looking rotor and added protection on exposed metal surfaces. This rotor measures 300 mm in outside diameter, 47.700 mm overall height, and 28.000 mm nominal thickness, with a 26.400 mm discard thickness specification. The vented construction and straight vane layout support front brake use on vehicles such as the Hyundai Sonata, Hyundai Tucson, Kia Optima, Kia Forte, Kia Forte5, Kia Forte Koup, Kia Sportage, Kia Rondo, Hyundai Veloster, and Hyundai ix35 where the listed fitment matches.

This part number 320.51020F is a direct-fit front disc brake rotor for select 2005-2018 Hyundai and Kia models, including applications that specify compatibility with 300 mm front rotors. It is a practical replacement choice when the original rotor is worn, scored, or affected by surface corrosion.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or thickness variation
• Scoring and uneven pad contact on the braking surface
• Corrosion on exposed rotor and hat surfaces
• Reduced braking consistency from an aged front rotor
• Noise related to worn or uneven rotor surfaces
