R1 Concepts 623-47087L RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-47087L RNC Series Drilled Brake Rotor is a high-performance, direct-fit replacement disc brake rotor engineered to deliver reliable stopping power and improved heat dissipation over standard OEM rotors. Built to original equipment manufacturer specifications, this rotor installs without modification for a straightforward replacement.

Key Features:

• Precision Cross-Drilled Holes: Drilled holes are countersunk and chamfered to maximize heat dissipation, reduce rotor temperature, and minimize the risk of cracking under repeated braking stress
• G3000 Grade Cast Iron Construction: Manufactured from G3000 iron grade for excellent stability, durability, and consistent braking performance
• Zinc Plated Coating: Full zinc plating on the hub and vane structure provides long-lasting corrosion resistance, extending rotor lifespan and maintaining appearance
• OEM Direct Fit: Engineered to OEM specifications — no drilling, cutting, or modifications required for installation
• Single Rotor (Left/Driver Side): Part number 623-47087L is the left-side (driver side) rotor; verify fitment for correct axle position

R1 Concepts recommends always replacing brake pads when installing new rotors and following a proper break-in (bed-in) procedure after installation to ensure optimal performance and even pad transfer. The zinc coating on the braking surface will naturally wear away during the bed-in process, which is normal and expected.
