Detailed Product Description

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating are engineered to meet the braking demands of BMW vehicles including the 323i, 325Ci, 325i, 325xi, 328Ci, 328i, Z3, and Z4 models. These rotors feature a fully coated disc and hat finish that helps prevent rust and corrosion, extending the rotor's service life. The vented rotor design with straight vanes enhances airflow, which aids in heat dissipation during braking, reducing the risk of brake fade under normal driving conditions.

With a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.803 inches (20.400 mm), these rotors maintain structural integrity and performance throughout their lifespan. The smooth surface finish ensures consistent pad contact and braking efficiency. The floating disc mounting system and 5 lug holes with a 120 mm bolt circle diameter provide secure and precise fitment for compatible BMW models.
