R1 Concepts 613-37000R RNC Series Slotted Brake Rotor

The R1 Concepts 613-37000R RNC Series Slotted Brake Rotor is a high-performance direct-fit replacement rotor engineered for drivers who demand improved braking performance over a standard OEM rotor. Featuring precision-machined slots across the rotor face, this rotor continuously sweeps debris, gases, and heat away from the pad surface, maintaining a clean contact patch and consistent bite throughout every stop.

Key Features:

• Slotted Rotor Design: Lateral slots evacuate brake dust, gases, and heat to prevent fade and maintain consistent braking feel
• G3000 Grade Cast Iron: Premium metallurgy delivers the right balance of strength, thermal capacity, and long service life
• Precision Balanced: Computer-balanced to minimize vibration and eliminate brake pedal pulsation
• OE-Style Hat Dimension: Direct bolt-on fitment with no modification required
• Corrosion-Resistant Coating: Non-braking surfaces are coated to resist rust and maintain a clean appearance
• Ready to Install: Pre-assembled and road-ready right out of the box

R1 Concepts rotors are manufactured to strict dimensional tolerances, ensuring proper caliper clearance and smooth, judder-free braking. The RNC slotted rotor is an excellent upgrade for daily drivers, weekend enthusiasts, and tow vehicles seeking a meaningful improvement in braking performance without the complexity of a full big-brake kit.
