R1 Concepts 830-03019R DFC GeoPerf Cross-Drilled Slotted Brake Rotor with GEOMET Coating

The R1 Concepts 830-03019R DFC GeoPerf is a cross-drilled and diamond-slotted brake rotor finished with industry-leading Geomet® anti-corrosion coating. Engineered for drivers who demand more from their braking system, this rotor delivers a performance upgrade over standard OEM blanks while maintaining everyday street usability.

The 830-series designation identifies this rotor as a fully drilled and slotted unit with Geomet coating applied to all non-friction surfaces. Geomet® is a zinc-aluminum flake coating developed by NOF Metal Coatings Group that provides superior rust and corrosion protection compared to standard zinc plating — keeping the hat, vanes, and non-swept surfaces protected through harsh conditions including road salt and moisture exposure.

Key Features:

• Cross-Drilled Holes — Improve heat dissipation and help expel gas and debris from the braking surface
• Diamond Slotted Pattern — Continuously sweeps the pad face clean for consistent bite and improved fade resistance
• Geomet® Anti-Corrosion Coating — Applied to all non-friction surfaces as standard; provides long-lasting rust protection without an upcharge
• Mill Balanced Construction — Precision balanced to minimize vibration and reduce feedback through the brake pedal
• Symmetric Split Core Casting — Enhances structural strength and thermal stability under repeated braking cycles
• G3000-Grade Cast Iron — OEM-equivalent metallurgy for reliable friction characteristics and pad compatibility
• Direct OEM Replacement Fitment — No modifications required; installs using factory hardware

Upon initial installation, the Geomet® coating will cover the entire rotor surface. During the break-in process, the coating naturally wears from the friction surface where pads make contact, leaving the hub, hat, and inner vane structure fully protected. A proper bed-in procedure is recommended to optimize pad transfer and maximize rotor life.

The R1 Concepts 830-03019R is compatible with a wide range of R1 brake pad compounds and can be paired as part of a complete front or rear brake kit for maximum performance and value.
