R1 Concepts 613-31142L RNC Series Slotted Brake Rotor

The R1 Concepts 613-31142L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered for drivers who demand improved stopping power and consistent braking feel. Part of R1 Concepts' RNC (Race N Cruise) line, this rotor is designed to deliver the benefits of a performance brake rotor while remaining street-legal and daily-driver friendly.

Key Features:

• Slotted design helps evacuate heat, gas, and debris from the rotor surface, maintaining consistent pad-to-rotor contact under demanding conditions
• Precision machined to strict OEM dimensional tolerances for a direct, no-modification-required fitment
• High-carbon grey iron construction provides superior heat dissipation and resistance to thermal cracking
• Zinc dichromate coating on non-friction surfaces helps resist corrosion and rust during storage and break-in
• Left-side (driver's side) application — confirm fitment before installation
• Balanced and tested to minimize vibration and pedal pulsation

The RNC slotted rotor is an excellent upgrade over standard blank rotors, offering improved bite and pedal feel whether used for spirited street driving or occasional track use. This rotor is sold individually and is intended as a direct replacement for the front or rear position as specified by fitment data.
