Product Line Features and Benefits

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating, High Carbon Content line focuses on delivering rotors that resist rust and maintain structural integrity under demanding conditions. The full coating on both the disc and hat surfaces helps prevent corrosion, extending rotor life. The high carbon content enhances thermal conductivity, which reduces the risk of brake fade and improves overall braking consistency. This product line is designed to meet or exceed OEM specifications, making it a suitable replacement for original equipment on compatible vehicles.

Technical Specifications and Design Details

This disc brake rotor features a nominal thickness of 1.181 inches (30.000 mm) and a discard thickness of 1.079 inches (27.400 mm), ensuring precise wear limits for safe operation. The rotor has an outside diameter of 12.598 inches (320.000 mm) and an overall height of 2.016 inches (51.200 mm). It includes a vented design with 34 curved vanes to optimize airflow and heat dissipation during braking. The rotor is mounted using a floating disc mounting system and has a 5-lug hole pattern with a bolt circle diameter of 4.409 inches (112.000 mm). The center hole diameter measures 2.642 inches (67.100 mm), and the hat ID is 6.047 inches (153.600 mm). The smooth surface finish supports consistent pad contact and braking performance.
