R1 Concepts 830-67057L DFC GeoPerformance Drilled Slotted Brake Rotor - Left

The R1 Concepts 830-67057L is a DFC GeoPerformance drilled and slotted brake rotor featuring a premium GEOMET corrosion-resistant coating. Engineered for drivers who demand improved stopping power and lasting durability, this left-side (driver side) rotor is a direct OE-style replacement that installs without modification.

Key Features:

• Cross-Drilled & Slotted Design: Drilled holes reduce heat buildup during hard braking, while slots improve pad bite and help evacuate gas and debris for more consistent performance in wet conditions
• GEOMET Corrosion-Resistant Coating: A premium silver-gray GEOMET finish is applied to the entire rotor — including the hat and vanes — for superior rust and corrosion protection compared to conventional paint or zinc coatings
• Ready to Install: The GEOMET coating is processed dry and shipped dry, requiring no cleaning or prep before installation
• 100% Electronic Inspection: Each rotor passes a rigorous electronic quality inspection measuring over 20 attributes to ensure it meets or exceeds OE specifications
• Left / Driver Side: This rotor is specifically designed for the left (driver) side of the vehicle — confirm your application before ordering
• Sold Individually: Quantity of one (1) rotor per order

The DFC GeoPerformance series combines performance-oriented drilled and slotted geometry with real-world corrosion protection, making it well-suited for daily driving, spirited street use, and light performance applications. The MPN 830-67057L follows DFC's established part number convention: the 830 prefix denotes the Drilled + Slotted + GEOMET configuration, and the L suffix designates the left/driver side fitment.
