R1 Concepts 613-40045L RNC Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-40045L is a slotted disc brake rotor from R1 Concepts' RNC series, engineered to deliver reliable stopping performance for everyday street driving. As a direct-fit replacement rotor, this unit is designed to bolt on in place of your worn OEM rotor with no modification required.

Key Features:

• Slotted Rotor Design: Slots channel away heat, gas, and brake debris from the pad surface, helping to prevent pad glazing and maintain consistent braking performance
• Zinc Plating: Protective zinc coating applied to the hat, hub, and vane areas to resist corrosion and extend rotor service life
• Double Disc Ground Braking Surface: Precision-finished braking surface promotes faster, more even pad bed-in and contributes to quieter, smoother operation
• Left/Driver Side Fitment: Part number suffix "L" designates this as the left-side (driver side) rotor
• OEM-Style Vented Construction: Internally vented design aids in heat dissipation during repeated braking cycles
• Direct Replacement: Designed as a drop-in replacement disc brake rotor requiring no modifications

R1 Concepts is a dedicated brake system manufacturer producing performance and OEM-style brake components including rotors, pads, calipers, and hardware. The 613-40045L is sold as a single rotor. A proper brake bed-in procedure is recommended after installation to fully seat the pad compound to the new rotor surface.
