R1 Concepts 830-80041L DFC GeoPerformance Drilled and Slotted Brake Rotor - Left

The R1 Concepts 830-80041L DFC GeoPerformance Brake Rotor is a cross-drilled and slotted performance disc brake rotor featuring a premium GEOSPEC corrosion-resistant coating. Engineered for maximum stopping power, durability, and reliability, this left-side rotor is a direct-fit upgrade over worn OEM brake rotors.

Key Features:

• Cross-Drilled Holes: Reduce heat buildup on the rotor surface during heavy braking and are chamfered to minimize the potential for stress cracking
• Diamond Slots: Clear brake dust, road debris, and gas from the pad/rotor interface to prevent pad glazing and maintain consistent bite
• GEOSPEC Corrosion-Resistant Coating: A superior silver-gray finish applied to the entire rotor that fights rust far better than conventional paint or zinc coatings — processed dry and shipped dry, ready to install with no additional preparation required
• G3000/G11H18 Cast Iron Construction: Premium iron castings formulated to OEM specifications for strength, stability, and long service life
• 100% Electronic Inspection: Every rotor passes a multi-attribute electronic quality check measuring over 20 specifications to ensure OE-level tolerances and trouble-free performance
• Left-Side Fitment: Directional rotor designed specifically for the left (driver's side) axle position

The 830-series DFC GeoPerformance rotor combines the performance benefits of a drilled and slotted surface with a premium GEOSPEC anti-corrosion finish, delivering improved wet-weather braking, reduced brake fade, and a clean appearance. This rotor is sold individually (single rotor).
