R1 Concepts 613-39023L RNC Series Slotted Brake Rotor

The R1 Concepts 613-39023L RNC Series Slotted Brake Rotor is a high-performance replacement rotor engineered to deliver consistent, reliable stopping power for daily driving and performance applications. Manufactured to strict dimensional tolerances, this rotor is a direct bolt-on replacement designed to restore or improve upon factory braking performance.

Key Features:

• Slotted Design: Precision-machined slots help evacuate heat, gas, and debris from the rotor surface, maintaining optimal pad-to-rotor contact and reducing brake fade under demanding conditions
• OE-Quality Construction: Cast from high-grade iron for durability, thermal stability, and long service life
• Direct-Fit Replacement: Engineered as a drop-in replacement to match factory specifications for a straightforward installation with no modifications required
• Improved Heat Dissipation: The slotted surface design promotes airflow across the rotor face, helping to manage operating temperatures during repeated braking events
• Left-Side Application: This part number (613-39023L) is specifically designated for the left (driver's side) position
• Corrosion-Resistant Finish: Features a protective coating on non-friction surfaces to resist rust and maintain appearance over time
