R1 Concepts 613-40038R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40038R is a slotted disc brake rotor from R1 Concepts' RNC (Race N' Control) Series, designed to deliver improved braking performance over stock rotors without sacrificing rotor longevity. The slotted design continuously sweeps the brake pad surface to clear heat, gas, and debris from the rotor face, maintaining a consistent and confident pedal feel under a variety of driving conditions.

Key Features:

• Slotted Rotor Design: Diamond-pattern slots sweep the pad surface clean, reducing brake fade and improving bite consistency during repeated stops
• G3000 Gray Iron Construction: High-grade cast iron formulation meets or exceeds OEM specifications for strength, thermal stability, and wear resistance
• Zinc Coating: Protective zinc plating applied to non-braking surfaces (hat, vanes, and edges) to resist corrosion and maintain a clean appearance
• Double Disc Ground Braking Surface: Precision-ground finish promotes faster, more even brake pad bed-in and contributes to quieter, smoother stops
• Direct OEM Replacement Fit: Engineered to bolt on in place of the factory rotor with no modifications required
• Meets or Exceeds OEM Standards: Manufactured to strict dimensional tolerances for proper caliper clearance and hub fitment

The R1 Concepts RNC Series slotted rotor is an ideal upgrade for drivers seeking a performance step above stock braking without the added heat stress associated with cross-drilled designs. It is well-suited for street driving, light performance use, and daily commuting where reliable, repeatable stopping power is a priority.
