R1 Concepts 830-21050R Drilled Slotted Performance Brake Rotor

The R1 Concepts 830-21050R is a high-performance drilled and slotted brake rotor from their GeoPerformance (DFC) line, engineered to deliver superior stopping power and heat dissipation for demanding driving conditions. This rotor features a precision-machined design with cross-drilled holes and curved slots that work together to evacuate heat, gases, and brake dust more efficiently than standard rotors.

Key Features:

• Cross-drilled and slotted design for maximum heat dissipation and wet weather performance
• Premium G3000 grade casting material for durability and consistent performance
• Electro-coating finish provides superior corrosion resistance
• CNC machined to OEM specifications for precise fitment
• Mill-balanced to minimize vibration and ensure smooth operation
• Silver zinc dichromate plating on non-friction surfaces

The drilled holes help reduce brake fade during aggressive driving by allowing hot gases to escape quickly, while the curved slots continuously clean the brake pad surface for consistent friction. This rotor is ideal for performance-oriented drivers seeking improved braking performance over stock rotors without compromising daily drivability.
