R1 Concepts 623-32017R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-32017R RNC Series Cross-Drilled Brake Rotor is a precision-engineered disc brake rotor designed to deliver enhanced stopping performance over standard OEM replacements. Built to direct-fit OEM specifications, this rotor installs without modifications for a straightforward, professional-quality brake service.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk to reduce heat stress and prevent cracking, dissipating heat efficiently and lowering rotor surface temperature for more consistent braking performance
• G3000 Grade Cast Iron Construction: Manufactured from high-grade G3000 cast iron for superior strength, longevity, and reliable heat tolerance
• Zinc Plated Corrosion Protection: Silver zinc plated coating shields the rotor hub and vane structure from rust and corrosion, extending service life and maintaining appearance
• Non-Directional Surface Finish: Prepared with a non-directional finish to promote faster, more even brake pad bed-in for quieter and smoother stops
• Direct OEM Replacement: Engineered to match OEM dimensions and mounting specifications — no cutting, drilling, or modification required
• Single Rotor (Right/Passenger Side): Sold individually as a right-side replacement rotor

The R1 Concepts RNC Series drilled brake rotor is an excellent upgrade for drivers seeking improved heat management and braking confidence over a standard blank replacement rotor. Compatible with R1 Concepts ceramic and OEM-equivalent brake pads for a complete brake system refresh.
