R1 Concepts 623-58018R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-58018R RNC Series Drilled Brake Rotor is a direct-fit, cross-drilled disc brake rotor engineered to deliver improved stopping performance over standard OEM rotors. Designed as a bolt-on replacement requiring no modifications, it is manufactured to original equipment specifications for a precise, hassle-free installation.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat buildup by dissipating thermal energy, helping prevent brake fade during repeated or heavy stops
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 cast iron for excellent strength, durability, and consistent braking performance mile after mile
• Zinc Plated Corrosion Protection: A protective zinc coating is applied to the hub and vane structure to guard against rust and corrosion, extending rotor life and maintaining appearance
• Double Disc Ground Surface: The braking surface is double disc ground to promote faster, more even brake pad bed-in and contribute to quieter, smoother stops
• Direct OE Fit: Manufactured to original equipment specifications — no drilling, cutting, or modification required for installation
• Single Rotor (1PC): Sold individually; order the quantity needed for your application

The R1 Concepts RNC Series drilled rotor is an ideal upgrade for drivers seeking enhanced heat management and improved braking responsiveness compared to a standard blank rotor. For best results, brake pads should always be replaced when installing new rotors, and a proper break-in procedure should be followed after installation.
