Product Line Details: Centric GCX Elemental Protection

The Centric GCX Elemental Protection Disc Brake Rotors - Full Coating line focuses on providing rotors with a complete protective coating to resist rust and corrosion. This full coating extends the rotor's service life, especially in environments prone to moisture and road salt exposure. The rotors feature a vented design with straight vanes to optimize cooling and maintain consistent braking performance under demanding conditions.

Technical Specifications and Features

This disc brake rotor is vented with straight vanes, allowing for efficient heat dissipation during braking. The rotor's smooth surface finish ensures consistent pad contact and braking response. The floating disc mounting design helps reduce stress and warping, improving rotor longevity. The rotor's dimensions include a 12.205 inch outside diameter and a nominal thickness of 0.701 inches, with a discard thickness of 0.650 inches to indicate when replacement is necessary. The hat and disc are fully coated to protect against corrosion, and the rotor includes five lug holes with a 4.5 inch bolt circle diameter, compatible with specified Lexus models.
