R1 Concepts 613-37000L RNC Slotted Brake Rotor

The R1 Concepts 613-37000L RNC Slotted Brake Rotor is a direct-fit performance replacement rotor engineered to deliver improved braking performance over stock. Part of R1 Concepts' RNC (Replacement Non-Coated) series, this rotor features precision-machined slots designed to continuously clean and deglaze brake pad surfaces, improve heat dissipation, and reduce brake fade during repeated stops.

Key Features:

• Slotted Surface Design: Machined slots sweep away heat, gas, and debris from the rotor-pad contact surface for consistent, fade-resistant braking
• Direct OE Replacement: Engineered to match original equipment specifications for a straightforward, no-modification installation
• Premium G3000 Cast Iron: Manufactured from high-grade G3000 metallurgy for long service life and excellent thermal stability
• Precision Balanced: Computer-balanced to minimize vibration and pedal pulsation
• Left-Side Application: Designed specifically as a left (driver's side) front or rear rotor — verify fitment before installation
• R1 Concepts Quality: Each rotor is inspected to meet or exceed OEM dimensional and performance standards

The 613-37000L is an ideal upgrade for drivers seeking better stopping performance than a standard smooth rotor without the aggressive nature of a fully drilled design. Whether used for daily driving or spirited street use, this slotted rotor pairs well with a variety of performance brake pad compounds.
