R1 Concepts 613-40052L RNC Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-40052L RNC Slotted Brake Rotor is a direct-fit, performance-oriented replacement rotor engineered for improved braking response and thermal management. The slotted rotor design continuously sweeps the brake pad surface to expel heat, gas, and debris from the contact zone, maintaining a clean and consistent pad bite under a wide range of driving conditions.

Key Features:

• Slotted Rotor Design – Slots channel heat and gases away from the braking surface for more consistent stopping performance
• Double Disc Ground Braking Surface – Promotes faster, more even brake pad bed-in and delivers quieter, smoother stops
• Zinc-Plated Coating – Corrosion-resistant finish protects the hat, vanes, and non-swept surfaces for a cleaner, longer-lasting appearance
• Direct OEM Replacement Fit – Engineered to match original equipment specifications for straightforward installation without modification
• Left/Driver Side Application – MPN suffix "L" designates this rotor for the left (driver's) side position
• High-Carbon Iron Construction – Provides excellent heat dissipation and structural rigidity under repeated braking demands

R1 Concepts recommends performing a proper brake bed-in procedure after installation. Note that the zinc coating on the pad-contact braking surface will wear away during initial break-in — this is normal and expected. The coating remains intact on the hub, vanes, and inner structure for ongoing corrosion protection.
