R1 Concepts 623-03063L RNC Series Drilled Brake Rotor

The R1 Concepts 623-03063L RNC Series Drilled Brake Rotor is a direct-fit replacement rotor engineered to deliver consistent, reliable stopping power. Designed as a direct OEM-style replacement with performance-oriented drilled venting, this rotor is built to meet or exceed original equipment specifications while improving heat dissipation and reducing brake fade during demanding driving conditions.

The drilled hole pattern allows heat, gas, and moisture to escape from the rotor surface, keeping the brake pad-to-rotor interface clean and cool. This helps maintain optimal friction performance and extends the service life of both the rotor and brake pads.

Key Features:

• Drilled rotor design for improved heat dissipation and reduced brake fade
• Direct OEM replacement fitment for precise installation
• Manufactured to meet or exceed OEM specifications
• Corrosion-resistant coating on non-friction surfaces to prevent rust and extend rotor life
• Precision-machined for minimal runout and smooth, vibration-free braking
• Compatible with OEM and performance brake pad compounds

R1 Concepts rotors undergo strict quality control to ensure each unit delivers the consistent, safe braking performance your vehicle demands. The 623-03063L is the left-side (driver side) rotor, making it easy to identify the correct part for your application.
