R1 Concepts 830-76143L Drilled Slotted Performance Brake Rotor

The R1 Concepts 830-76143L is a high-performance drilled and slotted brake rotor engineered to deliver superior stopping power and heat dissipation. Part of the DFC GeoPerf series, this rotor features a precision-machined design with both drilled holes and curved slots that work together to reduce brake fade, expel heat and gases, and maintain consistent braking performance under demanding conditions.

Key Features:

• Drilled and slotted design for maximum heat dissipation and gas evacuation
• GeoPerf geometrically designed slot pattern optimizes pad bite and reduces noise
• Premium G3000 metallurgy casting for durability and thermal stability
• Mill-balanced to minimize vibration and ensure smooth operation
• Enhanced cooling channels prevent brake fade during aggressive driving
• Cross-drilled holes help remove water, dust, and debris from braking surface
• Direct replacement for OEM rotors with no modifications required

This left-side rotor is ideal for performance enthusiasts, towing applications, and drivers who demand reliable braking performance. The combination of drilling and slotting provides the benefits of both technologies—improved wet weather performance, reduced brake fade, and extended pad life. R1 Concepts rotors are manufactured to strict quality standards and undergo rigorous testing to ensure optimal fit and function.
