R1 Concepts 830-31055D DFC GeoPerf Drilled Slotted Brake Rotor with GEOMET Coating

The R1 Concepts 830-31055D DFC GeoPerf Drilled and Slotted Brake Rotor delivers performance-grade stopping power with a premium Geomet anti-corrosion coating. Manufactured under the DFC (Dynamic Friction Company) product line, this rotor features cross-drilled holes and diamond-cut slots engineered to dissipate heat, channel away gas and debris, and maintain consistent pad bite under demanding driving conditions.

The Geomet coating provides superior rust and corrosion protection compared to standard zinc plating, protecting the hat, vanes, and non-braking surfaces for a cleaner, longer-lasting appearance throughout the rotor's service life. This is a direct OE-replacement fitment rotor that meets or exceeds factory specifications for a straightforward installation.

Key Features:

• Cross-Drilled & Slotted Design – Improves heat dissipation, reduces brake fade, and expels gas and debris from the rotor face for consistent stopping performance
• Geomet Coating – Premium corrosion-resistant finish protects non-braking surfaces for improved longevity and appearance
• DFC GeoPerf Series (830 Prefix) – Identifies this rotor as a drilled, slotted, and Geomet-coated unit within DFC's product lineup
• OE-Grade Metallurgy – Meets or exceeds original equipment specifications for proper fit and reliable performance
• Vented Construction – Internal vane design promotes airflow for continuous cooling during street and performance driving
• Suitable for everyday street driving, spirited driving, and light performance use

Break-In Notice: Upon initial installation, the Geomet coating covers the entire rotor surface. During the break-in bedding process, the coating will naturally wear from the braking surface where pad contact occurs, leaving the hat and inner vanes protected. A proper bedding procedure is recommended to seat the pads and maximize rotor performance.
