R1 Concepts 830-27046L DFC GeoPerformance Drilled Slotted Brake Rotor - Left

The R1 Concepts 830-27046L is a DFC GeoPerformance drilled and slotted brake rotor finished with Geomet corrosion-resistant coating. This is a left-side (driver side) rotor, as indicated by the "L" suffix in the part number. The 830-prefix DFC model designation identifies this as the full drilled and slotted configuration with Geomet protective coating — engineered for drivers seeking both improved performance and long-lasting appearance.

Key Features:

• Cross-Drilled Holes: Reduce heat buildup on the rotor surface during repeated braking, helping maintain consistent stopping performance
• Diamond Slotted Pattern: Increases pad bite and swept contact area, delivering shorter stopping distances — particularly effective in wet weather conditions
• Geomet Protective Coating: Industry-leading corrosion-resistant finish applied to the hat, hub, and vane structure for superior rust protection and a clean appearance over the life of the rotor
• Carbon Alloy Construction: Premium rotor material engineered for maximum performance, reliability, and durability across street and performance driving applications
• Direct-Fit Replacement: Designed as a drop-in replacement for the original equipment rotor — no modifications required
• Left-Side Application: This rotor is specifically designed for the driver-side (left) wheel position

Break-In Note: Upon receipt, the rotor's braking surface will be coated with Geomet finish. During the initial break-in process, the coating on the pad contact surface will wear away — this is normal. The Geomet coating will remain on the hat, vanes, and hub for continued corrosion protection.

The DFC GeoPerformance series is well-suited for daily street driving, spirited performance use, and drivers who want a high-quality upgrade over standard replacement rotors without sacrificing everyday drivability.
