R1 Concepts 623-16007L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-16007L is a drilled disc brake rotor from the R1 Concepts RNC Series, engineered as a direct OE-style replacement with enhanced performance characteristics. Designed as the left (driver) side rotor, this unit is precision-manufactured to meet or exceed original equipment specifications for a confident, reliable fit.

R1 Concepts RNC Series rotors feature cross-drilled holes that help evacuate heat, gas, and water from the rotor surface during braking, improving pad bite and reducing brake fade under repeated or heavy use. The rotor is manufactured from high-carbon grey iron for excellent thermal capacity and long service life.

Key Features:

• Cross-drilled design for improved heat dissipation and wet-weather braking performance
• Precision-balanced for smooth, vibration-free operation
• Direct OE replacement — no modifications required for installation
• High-carbon grey iron construction for durability and fade resistance
• Left (driver) side application
• Zinc-washed finish helps resist surface rust during storage and shipping

The R1 Concepts 623-16007L is ideal for drivers seeking an upgrade over standard smooth rotors while maintaining OE fitment and daily-driver reliability. Compatible with a range of OEM brake pad configurations.
