R1 Concepts 623-47008R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47008R is an RNC Series cross-drilled disc brake rotor engineered for reliable, high-performance stopping power. Manufactured from G3000 grade cast iron, this rotor delivers consistent braking performance while meeting or exceeding original equipment specifications — no modifications required for installation.

Key Features:

• Cross-Drilled Design: Precision-drilled and countersunk holes reduce rotor surface temperature by up to 105°F, enhancing heat dissipation and minimizing brake fade during extended or demanding use
• G3000 Cast Iron Construction: High-grade iron formulation provides excellent durability, thermal stability, and braking consistency mile after mile
• Zinc Plating Corrosion Protection: A protective zinc coating is applied to the hub and vane structure to resist rust and corrosion, extending rotor life and maintaining appearance
• Double Disc Ground Surface: Promotes a faster, more even brake pad bed-in process for quieter, smoother stopping performance right from the start
• OE Direct Fit: Manufactured to original equipment specifications for a direct bolt-on installation with no drilling, cutting, or modification required
• Chamfered Drill Holes: Countersunk and chamfered holes maintain structural integrity and reduce the risk of cracking under thermal stress

The R1 Concepts RNC Series drilled brake rotor is an ideal upgrade for drivers seeking improved thermal management and a performance-oriented look over a standard blank replacement rotor. Sold as a single rotor (1 piece). Always replace brake pads when installing new rotors and follow a proper bed-in procedure for best results.
