R1 Concepts 613-39026L RNC Slotted Brake Rotor Left Driver Side

The R1 Concepts 613-39026L RNC Slotted Brake Rotor is a high-performance, slotted disc brake rotor engineered for consistent stopping power and long-lasting durability. Designed as a direct-fit left/driver-side replacement, this rotor delivers a noticeable upgrade over standard OEM rotors without requiring any modifications.

The precision-machined slots on the braking surface continuously sweep debris, heat, and gases away from the pad contact area during braking. This helps reduce brake fade, improves pad bite, and promotes more consistent pedal feel under both everyday driving conditions and more demanding use.

Key Features:

• Slotted Design: Machined slots channel away heat, gas, and dust buildup for improved braking consistency and reduced fade
• Direct-Fit Replacement: Engineered to OEM specifications for a straightforward, no-modification installation
• Left/Driver-Side Application: Sold as a single rotor — part number suffix "L" designates left-side fitment
• G3000-Grade Cast Iron Construction: Premium iron alloy provides the strength and thermal capacity needed for reliable, long-term performance
• Double Disc Ground Braking Surface: Promotes faster, more even brake pad bed-in and delivers a quieter, smoother stop
• Balanced Vane Design: Internal vanes promote airflow through the rotor for efficient heat dissipation during braking

The R1 Concepts RNC Series is built for drivers who want a dependable, performance-oriented rotor at an accessible price point. Whether you're replacing a worn rotor or upgrading from stock, the 613-39026L is a solid choice for restored braking confidence and long service life.
