R1 Concepts 613-45016L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-45016L RNC Series Slotted Brake Rotor is a high-performance direct-fit replacement rotor engineered for drivers who demand improved braking response and extended rotor life. Designed as the left/driver-side rotor, this unit is a direct OEM-style replacement that installs without modification.

R1 Concepts' RNC slotted rotors feature precision-machined slots across the rotor face that continuously sweep the brake pad surface, clearing away heat, gas, and debris during braking. This design helps reduce brake fade under repeated or heavy braking conditions and promotes more consistent pad bite.

Key Features:

• Slotted rotor design for improved heat dissipation and pad degassing
• Left/driver-side fitment — verify fitment via your vehicle application guide
• Precision CNC machined for strict dimensional tolerances and balanced rotation
• High-carbon gray iron construction for durability and thermal stability
• Corrosion-resistant coating on non-contact surfaces to minimize rust and cosmetic deterioration
• Direct OEM replacement — no modifications required for installation
• Manufactured to meet or exceed OEM specifications
