R1 Concepts 623-58031R RNC Series Drilled Brake Rotor

The R1 Concepts 623-58031R RNC Series Drilled Brake Rotor is a precision-engineered performance disc brake rotor designed to deliver enhanced stopping power and improved thermal management over stock replacement rotors. Built to OEM fitment specifications, this rotor installs without modification for a straightforward upgrade to your braking system.

Key Features:

• Drilled Design: Cross-drilled holes are countersunk and chamfered to maximize heat dissipation, reduce rotor temperature, and resist cracking under repeated hard stops
• G3000 Grade Cast Iron Construction: Premium-grade iron provides consistent friction surface performance, excellent thermal stability, and long service life
• Zinc Plating Finish: Silver zinc anti-corrosion coating protects the hat, vanes, and non-contact surfaces from rust and corrosion, extending rotor longevity and maintaining appearance
• OEM Direct-Fit Design: Engineered to match original equipment specifications — no drilling, cutting, or modifications required for installation
• Balanced and Precision Machined: Each rotor is precision balanced to minimize vibration and pedal pulsation for smooth, consistent braking feel
• Sold Individually: This listing is for a single rotor; order the correct quantity for your application

The R1 Concepts RNC Series drilled brake rotor is an ideal choice for drivers seeking improved heat management and braking response compared to a standard blank rotor. Compatible with most OEM brake calipers and brake pads — always replace brake pads when installing new rotors and follow the proper break-in procedure to achieve optimal performance and longevity.
