R1 Concepts 623-03046L RNC Series Drilled Brake Rotor - Left/Driver Side

The R1 Concepts 623-03046L RNC Series Drilled Brake Rotor is a direct-fit, high-performance replacement rotor engineered for improved stopping power and consistent fade resistance. Designed as a left/driver-side front or rear rotor, it features a precision-drilled pattern that reduces heat buildup and expels gases and debris from the rotor surface during braking.

Key Features:

• Drilled Design: Cross-drilled holes reduce rotor surface temperature, improve wet-weather braking, and minimize brake fade under repeated stops
• OE-Matching Fitment: Manufactured to exact OEM dimensions for a direct bolt-on installation with no modifications required
• High-Carbon Gray Iron Construction: Provides superior thermal conductivity and long-term durability compared to standard rotors
• Corrosion-Resistant Coating: Zinc-washed or e-coated non-friction surfaces resist rust and corrosion for improved longevity and appearance
• Precision Balanced: Computer-balanced to minimize vibration, pulsation, and pedal feedback
• Left/Driver Side: Designed specifically for the left-side application — sold individually

The R1 Concepts RNC Series is ideal for drivers seeking a performance upgrade over standard blank rotors while maintaining daily-driver reliability. Each rotor is manufactured to strict quality standards and is a direct replacement for the OEM unit.
