R1 Concepts 613-54222L RNC Series Slotted Brake Rotor - Left/Driver Side

The R1 Concepts 613-54222L RNC Series Slotted Brake Rotor is a performance-engineered, slotted disc brake rotor designed as a direct-fit replacement for the left/driver-side front or rear brake position. Built to R1 Concepts' exacting quality standards, this rotor delivers improved braking performance over standard smooth rotors.

Key Features:

• Slotted Rotor Design: Precision-machined slots channel heat, gas, and debris away from the braking surface, maintaining consistent pad contact and reducing brake fade under demanding conditions
• Direct OEM Replacement Fit: Engineered to match original equipment mounting dimensions for a straightforward, hassle-free installation
• Left/Driver-Side Application: Designated position-specific fitment — part number suffix "L" confirms this is the left/driver-side rotor
• Corrosion-Resistant Coating: Protective zinc coating applied to non-braking surfaces to resist rust and extend rotor lifespan
• High-Carbon Grey Iron Construction: Premium casting material provides improved thermal capacity and quieter braking compared to standard rotors
• Balanced and G-Tested: Each rotor is tested for proper balance to minimize vibration and pedal pulsation

The R1 Concepts RNC Series is ideal for drivers seeking a performance upgrade over stock rotors without the added complexity of a drilled design. Compatible with OEM-style and performance brake pads, this slotted rotor is a reliable choice for street and light performance use.
