R1 Concepts 830-31066L Drilled & Slotted Brake Rotor - Front Left

The R1 Concepts 830-31066L is a high-performance drilled and slotted brake rotor from their eLine GeoPerformance (DFC GeoPerf) series. This front left rotor features a precision-engineered design that combines cross-drilling and slotting to optimize braking performance in both daily driving and spirited conditions.

Key Features:

• Cross-drilled and slotted design improves heat dissipation and reduces brake fade
• Slotted pattern helps evacuate gas, dust, and water from the braking surface
• OE-quality castings ensure proper fitment and reliability
• G3000 certified metallurgy provides consistent stopping power
• Black e-coating finish offers corrosion resistance and a clean appearance
• Non-directional drilling pattern for simplified installation
• Position-specific design for front left wheel application

The R1 Concepts eLine series delivers improved thermal management over standard rotors, making them an excellent upgrade for vehicles that experience heavy braking loads, towing, or performance driving. The combination of drilling and slotting creates a rotor that maintains better pad contact while extending pad and rotor life through superior cooling.
