R1 Concepts 623-02004L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-02004L RNC Series Drilled Brake Rotor is a precision-engineered replacement brake rotor designed to deliver reliable stopping performance. The cross-drilled hole pattern helps dissipate heat and gas buildup during braking, contributing to more consistent pedal feel and reduced brake fade under demanding driving conditions.

Key Features:

• Cross-Drilled Design: Drilled holes promote heat and gas venting to help maintain braking consistency and reduce fade
• Direct-Fit Replacement: Engineered to OEM specifications for a straightforward, bolt-on installation
• High-Carbon Iron Construction: Provides superior strength, durability, and vibration dampening compared to standard cast iron rotors
• Zinc Coating: Corrosion-resistant finish protects non-braking surfaces from rust and extends rotor life
• Left-Side Rotor: Part number 623-02004L is the left (driver-side) rotor
• OEM-Compatible Sizing: Matches original equipment dimensions for proper fitment and pad compatibility

R1 Concepts manufactures performance and OEM-replacement brake components and is a well-established brand in the aftermarket brake industry. The RNC series is designed for drivers seeking an upgrade over standard smooth rotors with the added benefit of a drilled surface, without sacrificing everyday drivability or ride comfort.
