R1 Concepts 623-31005L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-31005L RNC Series Drilled Brake Rotor is a direct-fit replacement rotor engineered to deliver reliable stopping performance for everyday driving. Designed as the left (driver's side) rotor, this unit features a precision-drilled pattern that helps dissipate heat and gases generated during braking, reducing brake fade and improving overall pad performance.

Key Features:

• Drilled Design: Cross-drilled holes promote heat dissipation and help evacuate gas buildup between the pad and rotor surface for consistent braking response
• OE-Style Direct Fit: Engineered to match original equipment specifications for a hassle-free, no-modification installation
• Corrosion-Resistant Coating: Non-braking surfaces feature a protective coating to resist rust and maintain a clean appearance
• Precision Balanced: Computer-balanced to minimize vibration and pedal pulsation during braking
• Left Side Application: Specifically designed for the driver's side (left) position — sold individually

The R1 Concepts RNC line is ideal for drivers seeking an affordable upgrade over plain OEM rotors without sacrificing reliability or fit. As with any brake component replacement, it is recommended to replace rotors in axle pairs and bed in new pads and rotors according to manufacturer guidelines for optimal performance.
