R1 Concepts 623-46064L RNC Drilled Brake Rotor Left Front

The R1 Concepts 623-46064L RNC Drilled Brake Rotor is a high-performance direct-fit replacement rotor engineered for improved stopping power and consistent braking feel. Designed as the left-side rotor, it features a drilled pattern that helps dissipate heat and gas buildup during heavy or repeated braking, reducing brake fade and extending pad life.

Key Features:

• Drilled rotor design promotes heat dissipation and reduces brake fade under demanding driving conditions
• Direct OEM replacement fit — no modifications required for installation
• Left-side application (driver's side) for precise fitment
• High-carbon grey iron construction provides durability and consistent rotor performance
• Corrosion-resistant coating on non-friction surfaces helps protect against rust and extends service life
• Precision machined to tight tolerances for smooth, vibration-free braking
• Compatible with OEM and aftermarket brake pad compounds

The R1 Concepts RNC series is built for drivers who want a performance upgrade over stock rotors without sacrificing daily drivability. This rotor is a reliable choice for street use and light performance driving applications.
