R1 Concepts 613-39029L RNC Series Slotted Brake Rotor

The R1 Concepts 613-39029L RNC Series Slotted Brake Rotor is a performance-engineered replacement rotor designed to deliver consistent stopping power and improved heat dissipation over standard OEM rotors. Built with precision slot patterns machined into the braking surface, this rotor continuously sweeps away gas, dust, and debris from the pad contact zone, maintaining a clean pad face and reducing brake fade under demanding driving conditions.

Key Features:

• Slotted Design: Precision-cut slots channel heat, gas, and brake dust away from the rotor surface for consistent performance
• RNC Series Construction: Manufactured to strict dimensional tolerances for a direct OEM-style fit with no modification required
• G3000 Grade Cast Iron: Premium iron alloy provides excellent thermal capacity, durability, and long rotor life
• Corrosion-Resistant Coating: Non-braking surfaces feature a protective coating to resist rust and maintain appearance
• Precision Balanced: Computer-balanced to minimize vibration and eliminate brake pedal pulsation
• Left-Side Fitment: This is the driver-side (left) rotor — order the corresponding right-side part for a complete axle set

The R1 Concepts RNC slotted rotor is an ideal upgrade for drivers who want improved braking performance and reduced heat buildup compared to a standard smooth rotor, without the aggressive wear profile of a drilled design. It is a direct bolt-on replacement suitable for street driving and spirited performance use.
