R1 Concepts 613-40038L RNC Slotted Brake Rotor

The R1 Concepts 613-40038L RNC Slotted Brake Rotor is a performance-grade replacement rotor engineered for drivers who demand more from their braking system. Designed as a direct-fit replacement, this rotor features precision-machined slots that continuously sweep the brake pad surface to expel heat, gases, and debris — keeping your pads clean and contact area maximized.

Key Features:

• Slotted Design: Precision-cut slots improve bite, reduce brake fade, and extend pad life by clearing debris and gases from the rotor face
• Direct OE Replacement: Engineered to match original equipment specifications for straightforward, hassle-free installation
• High-Carbon Iron Construction: Provides superior heat dissipation and long-lasting durability under repeated braking cycles
• Zinc Dichromate Coating: Corrosion-resistant finish protects the non-braking surfaces from rust and environmental wear
• Balanced for Smooth Operation: Computer-balanced to minimize vibration and eliminate pedal pulsation
• Left (Driver) Side Fitment: This is the left-hand rotor as indicated by the "L" suffix in the part number

The R1 Concepts RNC series is an excellent upgrade over standard OEM rotors for drivers looking to improve stopping performance on the street or during light track use. Sold individually.
