R1 Concepts 613-40004R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40004R is a RNC Series slotted brake rotor engineered to deliver consistent stopping power and improved thermal performance over stock replacement rotors. R1 Concepts designs the RNC line as a direct-fit upgrade, combining OEM-style fitment with performance-oriented features that benefit both daily drivers and enthusiasts.

Key Features:

• Slotted Surface Design: Machined slots sweep away heat, gas, and debris from the pad surface, maintaining consistent bite and reducing brake fade under demanding conditions
• Direct OEM Replacement: Engineered to match factory mounting dimensions for a straightforward, no-modification installation
• G3000 Metallurgy: Cast from high-grade G3000 gray iron for superior strength, wear resistance, and consistent performance across a broad temperature range
• Precision Balanced: Computer-balanced to minimize vibration and reduce pedal pulsation during braking
• Zinc Dichromate Coating: Protective coating applied to non-swept surfaces resists corrosion and maintains a clean appearance
• Drilled and slotted variants tested: RNC rotors undergo rigorous testing to ensure proper DTV (Disc Thickness Variation) tolerances are met

The R1 Concepts RNC slotted rotor is an ideal choice for drivers seeking a reliable, performance-oriented replacement that installs easily and provides improved heat dissipation compared to standard smooth-faced rotors.
