R1 Concepts 830-48049L DFC GeoPerf Drilled Slotted Disc Brake Rotor - Left

The R1 Concepts 830-48049L is a DFC GeoPerformance Drilled and Slotted Disc Brake Rotor engineered for drivers who want improved stopping performance without sacrificing rotor longevity. This is a left-side (driver's side) rotor featuring a cross-drilled and slotted design with a premium GEOSPEC corrosion-resistant coating.

Key Features:

• Cross-Drilled & Slotted Design: Drilled holes reduce heat buildup on the rotor surface, while the slots sweep away gas, dust, and debris for improved pad bite and shorter stopping distances — especially in wet conditions.
• GEOSPEC Corrosion Protection Coating: A proprietary finish applied over the entire rotor forms a durable, attractive silver-gray surface that resists rust far better than conventional paint or zinc coatings.
• Ready to Install: The GEOSPEC coating is processed dry and shipped dry — no cleaning of an oil-covered rotor is required, saving time during installation.
• 100% Electronic Inspection: Each rotor passes an electronic quality-control inspection measuring over 20 attributes to ensure it meets OE specifications before leaving the facility.
• Premium G3000 Iron Casting: Machined to tight tolerances for strength, stability, and durability that meets or exceeds OEM standards.
• Left-Side Application: Directional rotor designed specifically for the driver's side (left) axle position.

The DFC GeoPerformance series is a performance-oriented upgrade over standard blank rotors, offering enhanced thermal management and bite while maintaining street-friendly characteristics. Compatible with a proper break-in procedure for optimal pad seating and rotor performance.
