R1 Concepts 613-46013L RNC Series Slotted Brake Rotor

The R1 Concepts 613-46013L RNC Series Slotted Brake Rotor is a high-performance, slotted disc brake rotor engineered for drivers who demand improved stopping performance over a standard blank rotor. Designed as a direct OEM replacement with a performance upgrade, this rotor delivers consistent, fade-resistant braking under a wide range of driving conditions.

The RNC Series features directional surface slots that continuously sweep the brake pad face to remove heat, gas, and debris from the contact surface. This helps maintain consistent pad bite and reduces the risk of brake fade during repeated hard stops. The "L" designation indicates this is a left (driver) side rotor, engineered specifically for directional slot orientation on that position.

Key Features:

• Directional Slotted Surface — Slots channel heat, gas, and dust away from the pad-rotor interface for consistent braking performance
• Direct OEM Fitment — Engineered to match original equipment specifications for a straightforward installation
• Corrosion-Resistant Coating — Zinc-based protective coating on non-friction surfaces guards against rust and extends rotor life
• Vented Rotor Design — Internal vane structure promotes airflow for improved thermal management
• Left/Driver Side Specific — Directional slot pattern optimized for correct rotation on the driver-side position
• G3000 Grade Castings — High-quality gray iron casting provides durability and consistent braking characteristics

The R1 Concepts RNC Series is an excellent choice for street and performance driving applications where enhanced brake response and rotor longevity are priorities. A proper bed-in procedure is recommended after installation to fully seat the brake pads to the new rotor surface and achieve optimal braking performance.
