R1 Concepts 613-31145L RNC Slotted Brake Rotor

The R1 Concepts 613-31145L RNC Slotted Brake Rotor is a high-performance, slotted disc brake rotor engineered to deliver consistent stopping power and improved thermal management over stock replacement rotors. Designed as a direct-fit upgrade, this rotor installs in place of your factory unit with no modifications required.

Key Features:

• Slotted Rotor Design: Precision-machined slots channel heat, gas, and debris away from the braking surface, reducing brake fade and maintaining consistent pad bite under repeated heavy stops
• Nano Coating (RNC): The R1 Nano Coating provides a durable, corrosion-resistant finish that protects the rotor hat, vanes, and non-contact surfaces from rust and oxidation for improved longevity and appearance
• Direct OE Replacement Fit: Engineered to match original equipment specifications for straightforward installation without the need for additional hardware or modifications
• Improved Cooling Efficiency: Vented rotor construction promotes airflow through the internal vane structure, dissipating heat quickly and helping to maintain braking performance under demanding conditions
• Balanced Performance: Suitable for daily street driving as well as spirited driving where enhanced thermal performance and consistent pedal feel are priorities
• Quality Construction: Manufactured from high-grade grey iron casting, meeting or exceeding OEM dimensional tolerances for smooth, vibration-free operation

The R1 Concepts RNC series is an ideal choice for drivers seeking a step up in rotor performance and corrosion protection without moving to a fully drilled and slotted design. A proper brake bed-in procedure is recommended after installation to maximize pad transfer and rotor performance.
