R1 Concepts 830-60006L DFC GeoPerformance Drilled Slotted Brake Rotor - Left

The R1 Concepts 830-60006L is a DFC GeoPerformance Drilled and Slotted Brake Rotor engineered for drivers who demand enhanced stopping power and long-term durability. Produced by Dynamic Friction Company (DFC) — the manufacturing partner behind R1 Concepts rotors — this left-side rotor combines cross-drilled holes and precision slots for improved braking response in both everyday and performance driving conditions.

Key Features:

• Cross-Drilled & Slotted Design: Drilled holes dissipate heat buildup while slots channel away gases and debris, providing more consistent pad bite and shorter stopping distances — especially in wet weather
• GeoPerformance (GEOSPEC) Coating: Features a patented corrosion-resistant finish that forms a durable, attractive silver-gray surface — superior protection compared to conventional paint or zinc coatings
• Dry Ship Ready: The GEOSPEC coating is processed dry and shipped dry, requiring no additional cleaning or preparation before installation
• Premium G3000/G11H18 Iron Casting: Formulated to OEM specifications for strength, stability, and durability
• 100% Electronic Inspection: Every rotor passes an automated quality inspection measuring over 20 attributes to ensure it meets OE tolerances
• Non-Directional Surface Finish: Promotes faster, more even brake pad bed-in for quieter, smoother stops right from the start
• Left-Side Fitment (L): Driver-side rotor — sold individually

The 830-prefix model designation confirms this rotor features the full Drilled + Slotted + GeoPerformance coating treatment. Compatible with DFC and R1 Concepts brake pads for optimized system performance.
