R1 Concepts 613-37005L RNC Slotted Brake Rotor

The R1 Concepts 613-37005L RNC Slotted Brake Rotor is a performance-grade replacement rotor engineered for drivers who demand improved stopping power and consistent brake feel. Designed as a direct OEM-style fitment, this rotor installs without modifications for a straightforward upgrade over worn factory rotors.

The slotted rotor surface features precision-machined slots that continuously clean and deglaze brake pads during use, promoting fresh pad bite and consistent pedal response. The slots also help expel heat, gas, and debris from the rotor face, reducing brake fade under demanding driving conditions.

Key Features:

• Slotted rotor design for improved pad bite and reduced glazing
• Precision machined to tight tolerances for smooth, vibration-free braking
• Direct OEM replacement — no modification required for installation
• Heat dissipation slots help reduce brake fade during spirited or heavy use
• Manufactured by R1 Concepts, a trusted name in performance braking
• Left-side (driver side) fitment as indicated by the "L" suffix in the part number

The R1 Concepts RNC series offers a balanced upgrade for daily drivers and enthusiasts alike, combining durability and performance at a competitive value. This rotor is sold individually and is intended for the left/driver-side position.
