R1 Concepts 623-48000L RNC Series Drilled Brake Rotor

The R1 Concepts 623-48000L is a precision-drilled brake rotor from R1 Concepts' RNC Series, engineered to deliver reliable stopping power and enhanced thermal performance. Manufactured to OEM-equivalent specifications, this rotor is a direct-fit replacement that requires no modification for installation.

R1 Concepts rotors are cast from G3000 grade cast iron, providing excellent durability and heat dissipation. The cross-drilled holes improve ventilation, help evacuate heat, gas, and brake dust from the rotor surface, and contribute to consistent braking performance under demanding conditions.

Key Features:

• Drilled Design: Cross-drilled holes enhance rotor ventilation and help dissipate heat buildup for consistent performance
• G3000 Cast Iron Construction: High-quality cast iron formulation for durability and long service life
• Zinc Plated Coating: Protects against corrosion for improved appearance and longevity
• OEM-Equivalent Fitment: Direct bolt-on replacement with no modifications required
• Left-Side Specific: Designed and balanced specifically for the left (driver-side) position
• Precision Machined: Tight tolerances minimize vibration and help eliminate brake pedal pulsation

The R1 Concepts 623-48000L is sold as a single rotor and is designed for drivers seeking a performance-oriented upgrade or quality OEM replacement. For best results, R1 Concepts recommends replacing rotors in axle pairs and following the proper break-in procedure after installation.
