R1 Concepts 613-31176L RNC Series Slotted Brake Rotor

The R1 Concepts 613-31176L is a premium slotted brake rotor from R1 Concepts' RNC (Race & Performance) series, engineered for drivers who demand improved braking performance over standard OEM rotors. Designed as a direct-fit replacement, this rotor installs without modifications and restores or enhances your vehicle's stopping power.

Key Features:

• Slotted Design: Precision-machined slots channel away heat, gas, and debris from the rotor face, reducing brake fade and maintaining consistent pedal feel under demanding conditions
• Left-Side Application: Specifically designed for the driver-side (left) position — always verify side-specific fitment before installation
• High-Carbon Metallurgy: R1 Concepts rotors are cast from high-carbon iron alloy for improved thermal capacity and longer service life compared to standard cast iron rotors
• Zinc Dichromate Coating: Anti-corrosion coating on non-friction surfaces helps prevent rust and keeps the rotor looking clean during service life
• Direct OEM Replacement: Engineered to match original equipment specifications for hub bore, lug pattern, and hat height for a hassle-free installation
• Balanced and Ready to Install: Computer-balanced to minimize vibration and ensure smooth, judder-free braking from day one

R1 Concepts is a trusted name in the performance brake market, offering a range of rotor styles to suit everything from daily driving to track use. The RNC slotted rotor is an excellent upgrade for drivers seeking better heat management and consistent braking performance without the aggressive wear profile of a drilled rotor.
