R1 Concepts 613-47018L RNC Series Slotted Brake Rotor

The R1 Concepts 613-47018L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand consistent, reliable stopping power. Manufactured to strict dimensional tolerances, this rotor is a direct OE-style fitment designed as a left-side replacement.

Key Features:

• Slotted Design: Precision-machined slots sweep away gas, heat, and debris from the rotor surface, maintaining a clean contact patch with the brake pad for fade-resistant performance
• High-Carbon Iron Casting: Formulated for superior heat dissipation and reduced brake noise compared to standard grey iron rotors
• Direct OE Replacement: Engineered to match factory specifications for straightforward, no-modification installation
• Zinc Dichromate Finish: Protective coating resists rust and corrosion on non-swept surfaces, extending rotor life and maintaining a clean appearance
• Computer-Balanced: Precision balanced to minimize vibration and pedal pulsation during braking
• Left-Side Application: Designated left (driver-side) fitment — confirm vehicle application before installation

R1 Concepts RNC Series rotors are a trusted upgrade for daily drivers and performance enthusiasts seeking improved thermal management and consistent brake feel over the life of the rotor. Compatible with OE and most performance brake pad compounds.
