R1 Concepts 830-21041L Drilled Slotted Performance Brake Rotor - Front Left

The R1 Concepts 830-21041L is a high-performance drilled and slotted brake rotor designed to deliver superior stopping power and heat dissipation. Part of R1 Concepts' GeoPerformance line, this front left rotor features a precision-engineered drill and slot pattern that helps evacuate heat, gases, and brake dust while maintaining consistent pad contact for reliable braking performance.

Key Features:

• Drilled and slotted design for maximum heat dissipation and gas evacuation
• GeoPerformance coating provides enhanced corrosion resistance and appearance
• Precision-machined from high-quality castings for optimal balance and runout
• Direct OEM replacement fitment for easy installation
• Front left position application
• Engineered to reduce brake fade during aggressive driving or heavy loads

R1 Concepts rotors are designed for drivers seeking upgraded braking performance without sacrificing reliability. The drilled and slotted configuration combines the benefits of both designs—drilled holes reduce weight and improve cooling, while slots continuously clean the brake pad surface and expel debris for consistent friction.
