R1 Concepts 613-39009L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-39009L RNC Series Slotted Brake Rotor is a direct-fit, performance-oriented replacement rotor engineered for improved braking performance and extended service life. Part of R1 Concepts' RNC (Rotor Nano Coat) line, this rotor features a premium nano-coating that provides superior corrosion resistance, helping to prevent rust and oxidation that commonly affects bare metal rotors — keeping the rotor looking clean and performing reliably from the first stop.

Key Features:

• Slotted Design: Strategically machined slots channel away heat, gas, and debris from the pad surface, maintaining consistent pad bite and reducing brake fade during demanding use
• Nano Coat Finish: A thin, durable nano-coating is applied to non-friction surfaces to resist rust and corrosion, extending the cosmetic and functional life of the rotor
• Direct-Fit Replacement: Engineered to OEM specifications for hassle-free installation without modification
• Left/Driver Side Fitment: This is the left (driver) side rotor — verify pairing with the corresponding right-side part for axle sets
• G3000 Grade Iron Casting: Manufactured from high-grade G3000 iron for consistent friction performance, durability, and proper thermal mass
• OE-Style Venting: Internal vane configuration matches OEM design for efficient heat dissipation during normal and spirited driving

R1 Concepts brake rotors are designed, tested, and manufactured to meet or exceed OEM standards. The RNC slotted rotor is an excellent upgrade for drivers seeking better braking response and improved resistance to brake fade compared to a standard smooth replacement rotor.
