R1 Concepts 623-03048L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-03048L RNC Series Drilled Brake Rotor is a premium left-side replacement rotor engineered to deliver consistent, reliable stopping power for street and performance driving applications. Manufactured to meet or exceed OEM specifications, this rotor is a direct bolt-on replacement designed for a precise, hassle-free installation.

Key Features:

• Drilled Design: Cross-drilled holes promote heat dissipation, reduce brake fade during repeated stops, and help expel gases and debris from the rotor surface for more consistent braking performance
• OEM-Quality Fit: Engineered as a direct replacement to match original equipment dimensions and mounting specifications
• Left-Side Application: Specifically designed for the driver-side (left) wheel position — always verify fitment before installation
• Corrosion-Resistant Finish: Features a protective coating on non-friction surfaces to resist rust and corrosion during storage and normal use
• Balanced Construction: Precision-machined for minimal runout and vibration-free braking, helping prevent brake pedal pulsation
• Street and Performance Use: Suitable for daily driving as well as light performance use where improved thermal management is desired

The R1 Concepts RNC drilled rotor pairs perfectly with R1 Concepts brake pads for a matched braking system, but is also compatible with most aftermarket and OEM-style brake pads. Whether you are replacing a worn rotor or upgrading your braking setup, the 623-03048L delivers dependable performance and long service life.
