R1 Concepts 623-27043R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-27043R is a precision-engineered drilled disc brake rotor from the RNC Series, designed as a direct-fit replacement that delivers improved braking performance over standard OEM rotors. Built from high-grade G3000 cast iron, this rotor features cross-drilled holes that promote heat dissipation, help evacuate gases and moisture from the rotor surface, and reduce overall rotor weight for more responsive braking.

Key Features:

• Cross-Drilled Design: Precision-drilled holes channel heat away from the braking surface, reducing brake fade and improving stopping consistency
• G3000 Cast Iron Construction: High-grade metallurgy ensures durability, even wear, and quiet operation
• Direct OEM Replacement: Engineered for a precise drop-in fit with no modifications required
• Zinc Coating: Protective zinc plating on non-braking surfaces resists corrosion and rust for extended service life and a clean appearance
• Balanced Vane Design: Internal vanes promote airflow for continuous cooling during aggressive braking
• Single Rotor: Sold individually — this listing covers the right-side rotor

R1 Concepts rotors are manufactured to meet or exceed OEM specifications, making the 623-27043R a reliable upgrade for drivers seeking enhanced thermal management and a cleaner wheel appearance without sacrificing ride comfort or daily drivability.
