R1 Concepts 830-21034L Drilled & Slotted Brake Rotor - Left Front Performance Rotor

The R1 Concepts 830-21034L is a high-performance drilled and slotted brake rotor designed to deliver superior stopping power and heat dissipation. Part of the GeoPerformance (DFC GeoPerf) series, this left front rotor features precision-machined cross-drilling and slotting patterns that work together to reduce brake fade, evacuate gases and debris, and maintain consistent brake performance under demanding conditions.

Key Features:

• Drilled and slotted design for maximum heat dissipation and wet weather performance
• Left front position-specific rotor for optimal fitment
• Premium G3000 grade castings for durability and strength
• Mill-balanced to minimize vibration and ensure smooth operation
• Black e-coating finish helps prevent corrosion during shipping and storage
• Direct OEM replacement for easy installation

R1 Concepts rotors are engineered to provide enhanced braking performance for street, performance, and towing applications. The cross-drilled holes improve cooling and reduce unsprung weight, while the precision-cut slots continuously refresh the brake pad surface for consistent friction and shorter stopping distances.
