R1 Concepts 830-76171R DFC GeoPerf Drilled Slotted Performance Brake Rotor

The R1 Concepts 830-76171R is a DFC GeoPerf Series drilled and slotted brake rotor engineered for drivers who demand enhanced braking performance over factory-stock components. Combining precision drilling and aggressive slotting in a single rotor, this unit delivers superior heat dissipation, reduced brake fade, and consistently confident stopping power under a wide range of driving conditions.

Key Features:

• Drilled & Slotted Design: Cross-drilled holes reduce rotor mass and allow heat and gases to escape, while slots sweep away brake dust and debris for a clean, consistent pad contact surface
• GeoPerf Geometry: R1 Concepts' proprietary slot and drill pattern is engineered for optimal thermal performance and pad bite
• Premium G3000 Metallurgy: Cast from high-carbon G3000-grade iron for excellent thermal capacity, reduced noise, and longer service life
• Zinc Dichromate Coating: Non-braking surfaces feature a corrosion-resistant zinc coating to prevent rust and maintain a clean appearance
• OE-Grade Precision Balancing: Computer-balanced to minimize vibration and pedal pulsation for smooth, fade-free braking
• Direct OEM Replacement Fit: Designed as a bolt-on replacement — no modifications required

The R1 Concepts DFC GeoPerf rotor is an ideal upgrade for performance-minded drivers seeking improved brake feel, shorter stopping distances, and better heat management compared to standard OEM rotors. Each rotor is manufactured to strict dimensional tolerances and is ready to install straight out of the box.
