Key Features:

• Cross-Drilled Pattern: Precision-drilled holes are chamfered and countersunk to prevent cracking, reduce heat buildup, and improve bite during braking
• G3000 Grade Cast Iron Construction: High-quality base material engineered for consistent performance and long service life
• Zinc Plating: Silver zinc coating protects the rotor hub and vane structure from corrosion, improving appearance and extending rotor longevity
• OEM-Grade Direct Fit: Built to original equipment specifications for a hassle-free, no-modification installation
• Improved Heat Dissipation: Drilled holes enhance airflow across the rotor surface, reducing thermal buildup and brake fade during repeated stops
• Vented Design: Internal vane structure promotes cooling for consistent braking performance under varied driving conditions

The R1 Concepts RNC Series drilled rotor is an ideal upgrade or direct replacement for drivers seeking improved braking performance over stock rotors. Compatible with OEM brake pads or R1 Concepts replacement pad sets.
