R1 Concepts 623-20006L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-20006L is an RNC Series cross-drilled disc brake rotor engineered to deliver reliable stopping performance and extended service life. Precision-manufactured to OEM dimensions, this rotor is a direct-fit replacement that installs without modification.

R1 Concepts' drilled rotor design promotes improved heat dissipation during braking, helping to reduce brake fade under repeated or heavy braking conditions. The strategically placed drill holes allow hot gases and debris to escape from the rotor surface, maintaining consistent pad-to-rotor contact and braking efficiency.

Key Features:

• Cross-drilled rotor design for enhanced heat dissipation and reduced brake fade
• Direct OEM replacement — no cutting, drilling, or modification required
• Precision-balanced construction for smooth, vibration-free braking
• Corrosion-resistant coating on non-braking surfaces for long-term durability
• Manufactured to strict dimensional tolerances for proper fitment and pad compatibility
• Left/driver-side application (L suffix)

The R1 Concepts 623-20006L is designed for drivers seeking a performance upgrade over a standard blank rotor without sacrificing daily drivability. Pair with R1 Concepts brake pads for optimized system performance and even wear.
