R1 Concepts 613-21047L RNC Series Slotted Brake Rotor

The R1 Concepts 613-21047L RNC Series Slotted Brake Rotor is a direct-fit performance brake rotor engineered to deliver improved stopping power and consistent fade resistance over the OEM replacement. Designed for drivers who demand more from their braking system, this rotor features a precision-machined slotted surface that continuously sweeps debris, gas, and heat away from the brake pad contact area for cleaner, more reliable braking performance.

Key Features:

• Slotted Rotor Design: Machined slots channel away brake dust, gases, and water to maintain optimal pad-to-rotor contact and reduce brake fade under repeated stops
• Precision Balanced: Computer-balanced construction minimizes vibration and pedal pulsation for a smooth, confident braking feel
• Direct OEM Replacement: Engineered to match factory mounting specifications for a straightforward, no-modification installation
• Corrosion-Resistant Finish: Zinc or e-coat finish on the non-contact surfaces protects against rust and extends rotor service life
• High-Grade Iron Alloy: Premium cast iron construction provides consistent thermal stability and long rotor life under normal and spirited driving conditions
• Left-Side Application: This part number (613-21047L) is designated for the driver-side (left) position

The R1 Concepts RNC Series is an ideal upgrade for daily drivers and enthusiasts looking to improve braking performance without the cost of a full big-brake kit. Pair with quality brake pads for best results.
