R1 Concepts 623-11006L RNC Drilled Brake Rotor Left Side

The R1 Concepts 623-11006L RNC Drilled Brake Rotor is a premium replacement rotor engineered for improved braking performance and durability. Designed as a direct OE replacement, this rotor features a drilled pattern that promotes heat dissipation and helps reduce brake fade under demanding driving conditions. This is the left (driver) side rotor.

Key Features:

• Drilled design promotes heat dissipation and reduces brake fade
• Drilled holes help expel water, gas, and debris from the rotor surface for consistent stopping power
• Manufactured to OE specifications for a precise, no-modification fit
• Corrosion-resistant finish helps protect against rust and extends rotor service life
• Balanced and precision-machined for smooth, vibration-free braking
• Direct bolt-on installation — no drilling, cutting, or modifications required
• Left (driver) side application

R1 Concepts rotors are designed for drivers who demand reliable, consistent braking performance. The RNC series drilled rotor is a popular upgrade over stock rotors, offering improved thermal management while maintaining OE-level fitment and reliability.
