StopTech 320.40107F Centric GCX Elemental Protection Brake Rotor

The StopTech 320.40107F is a Centric GCX brake rotor featuring Elemental Protection GEOMET coating technology, engineered to restore OE braking performance while delivering superior corrosion resistance and extended service life.

GCX rotors are built with a dual-coating approach: a partial GEOMET coating on the friction surface accelerates pad bed-in by approximately 10% and eliminates unsightly corrosion rings, while full GEOMET coating on all non-mating and non-friction surfaces provides long-lasting protection against rust and environmental wear. The result is a rotor that arrives road-ready — no additional prep or break-in surface treatment required before installation.

Key Features:

• GEOMET Elemental Protection Coating on all non-friction surfaces for long-lasting corrosion resistance
• Partial friction-surface coating promotes up to 10% faster pad bed-in and eliminates corrosion rings
• Double disc ground to eliminate disc thickness variation (DTV) right out of the box
• OE-style vane design and machined non-friction surfaces restore factory looks and airflow performance
• Road-ready from the box — no additional prep needed before installation
• Engineered to meet or exceed OE performance standards for braking feel and stopping distance

The StopTech 320.40107F is a direct-fit replacement rotor designed as a precise drop-in for factory brake systems and stock calipers, making it an ideal upgrade for drivers seeking improved durability and corrosion protection over a standard uncoated replacement rotor.
