R1 Concepts 613-47037L RNC Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-47037L RNC Slotted Brake Rotor is a performance-grade, slotted disc brake rotor engineered for consistent stopping power and extended service life. Designed as a direct OE replacement with a performance upgrade, this left/driver-side rotor delivers confident, fade-resistant braking for everyday street driving and spirited performance use.

Key Features:

• Slotted Rotor Design: Precision-machined slots increase brake pad bite, channel heat and gases away from the braking surface, and serve as a built-in wear indicator to alert you before the rotor reaches minimum thickness
• Zinc Plating: Full corrosion-resistant zinc coating protects the rotor hat, vanes, and non-contact surfaces from rust and oxidation, extending service life and maintaining a clean appearance behind the wheel
• OE-Quality Casting: Manufactured from high-grade gray iron to OEM dimensional tolerances for a precise, no-modification installation
• Vented Construction: Internal vane design promotes airflow and heat dissipation to reduce brake fade during repeated or aggressive stops
• Left/Driver-Side Fitment: This unit (613-47037L) is the left-side rotor; sold individually
• Direct Bolt-On Replacement: Meets or exceeds OEM specifications for a straightforward swap without modifications

R1 Concepts RNC Series rotors are an ideal upgrade for drivers seeking improved braking performance over stock rotors without the added cost of a full cross-drilled and slotted kit. A proper bed-in procedure is recommended after installation to ensure optimal pad transfer and rotor performance.
