R1 Concepts 623-03037L RNC Series Drilled Brake Rotor

The R1 Concepts 623-03037L RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver confident, consistent stopping power. Manufactured to OEM specifications and beyond, this rotor features a cross-drilled pattern that improves heat dissipation, reduces brake fade, and helps evacuate gas and debris from the rotor surface during braking.

Key Features:

• Cross-Drilled Design: Strategically placed drill holes reduce rotor surface temperature, minimize brake fade, and improve wet-weather braking performance
• Premium G3000 Castings: Made from high-grade G3000 gray iron for durability, consistent performance, and long service life
• Precision Balanced: Computer-balanced to minimize vibration and ensure smooth, quiet braking
• Corrosion-Resistant Coating: Zinc dichromate or e-coating on non-friction surfaces protects against rust and corrosion during storage and use
• OEM Dimensions: Engineered to exact OEM specifications for a direct bolt-on fit with no modifications required
• Vented Construction: Internal vane venting promotes airflow through the rotor for additional thermal management

The R1 Concepts RNC (Drilled) series is a popular upgrade for drivers seeking improved braking aesthetics and performance over standard blank rotors. This rotor is a direct replacement designed for straightforward installation and is compatible with OEM and most aftermarket brake calipers and pads.
