R1 Concepts 623-11007R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-11007R RNC Series Drilled Brake Rotor is a direct-fit replacement disc brake rotor engineered to deliver improved stopping performance over a standard blank rotor. Built to original equipment specifications, this rotor installs without modification and is designed for drivers seeking a performance upgrade for street driving, daily commuting, and light performance use.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk and chamfered to reduce heat stress, prevent cracking, and allow heat and gases to escape efficiently—reducing rotor operating temperature for more consistent braking performance.
• G3000 Grade Cast Iron Construction: Manufactured from G3000 grade cast iron for excellent durability, thermal stability, and braking consistency that meets or exceeds OEM standards.
• Zinc Plating Corrosion Protection: The rotor is zinc-plated across the hat, hub, and vane surfaces to resist rust and corrosion, extending service life and maintaining a clean appearance behind the wheel.
• Double Disc Ground Surface: The braking surface is double disc ground to promote faster, more even brake pad bed-in and deliver quieter, smoother stops from the start.
• Direct OE-Spec Fit: Engineered to original equipment manufacturer specifications—no cutting, drilling, or modification required for installation.
• Single Rotor (1PC): Sold individually; order the quantity needed for your application.

The R1 Concepts RNC Series drilled brake rotor is an ideal upgrade for drivers who want improved heat dissipation and a cleaner, performance-inspired look without sacrificing ride comfort or day-to-day drivability. Always replace brake pads when installing new rotors and follow the recommended bed-in procedure for best results.
