R1 Concepts 613-40002L RNC Slotted Brake Rotor Left/Driver Side

The R1 Concepts 613-40002L RNC Slotted Brake Rotor is a direct-fit, left/driver-side replacement rotor engineered to deliver consistent stopping power and improved thermal performance over a standard OE-style rotor. Designed for drivers who demand more from their brake system without sacrificing everyday drivability, this rotor is a reliable upgrade for street and light performance use.

Key Features:

• Slotted Surface Design: Precision-machined slots channel away heat, gas, and brake dust to maintain consistent pad contact and reduce brake fade under repeated heavy stops
• Left/Driver Side Fitment: Purpose-built for the driver-side position — part number suffix "L" confirms correct directional orientation
• Direct OE Replacement: Engineered to match original equipment mounting dimensions for straightforward bolt-on installation with no modifications required
• High-Carbon Iron Casting: Premium metallurgy provides superior heat dissipation and rotor longevity compared to standard gray iron rotors
• Zinc Dichromate Coating: Non-friction surfaces are coated to resist corrosion and maintain a clean appearance throughout the rotor's service life
• Precision Balanced: Factory-balanced to minimize vibration and pedal pulsation for a smooth, confident braking feel

The R1 Concepts RNC series is a trusted choice for drivers looking to restore or improve their vehicle's braking performance with a quality aftermarket rotor. As with all brake rotor replacements, rotors should be installed in axle pairs and paired with fresh brake pads for optimal performance and even wear.
