R1 Concepts 613-40039R RNC Series Slotted Brake Rotor

The R1 Concepts 613-40039R RNC Series Slotted Brake Rotor delivers consistent, reliable stopping power for everyday driving and performance applications. Engineered with precision-cut slots across the rotor face, this rotor continuously sweeps the brake pad surface to expel heat, gas, and debris — maintaining optimal pad-to-rotor contact and reducing brake fade under demanding conditions.

Key Features:

• Slotted Rotor Design: Precision-machined slots channel heat and gases away from the braking surface for improved performance and pad life
• RNC Series Construction: Manufactured to OE specifications for a direct, no-modification-required fitment
• Corrosion-Resistant Finish: Protective coating helps resist rust and corrosion during storage and normal use
• Balanced and True: Computer-balanced to minimize vibration, pulsation, and pedal feedback
• Direct OE Replacement: Engineered as a direct replacement for worn or damaged factory rotors

R1 Concepts brake rotors are manufactured under strict quality control standards to ensure consistent performance, durability, and safe stopping distances. The RNC slotted rotor is an excellent upgrade over standard smooth rotors, offering improved heat dissipation and a cleaner pad surface with every stop.
