R1 Concepts 623-54279R RNC Series Drilled Brake Rotor

The R1 Concepts 623-54279R is a drilled brake rotor from R1 Concepts' RNC series, engineered to deliver reliable stopping power and improved thermal performance over a standard blank rotor. The cross-drilled hole pattern promotes heat dissipation and helps evacuate gas buildup between the pad and rotor surface, reducing brake fade during repeated or aggressive stops.

Key Features:

• Drilled Rotor Design – Cross-drilled holes improve airflow and heat dissipation, extending pad and rotor life
• Silver Zinc Plating – Corrosion-resistant coating protects the hub, hat, and vane structure from rust and oxidation
• Precision Machined – Manufactured to OEM fitment tolerances for proper installation and minimal runout
• Direct OEM Replacement – Designed as a direct-fit replacement for straightforward installation with no modifications required
• R1 Concepts RNC Series – Part of R1 Concepts' performance rotor lineup built for everyday drivers seeking improved braking over stock

The silver zinc coating covers the rotor fully at the time of shipment. During the break-in process, the coating on the braking surface will wear away as designed, leaving the hub and inner vane structure protected. A proper bed-in procedure is recommended to ensure optimal pad transfer and long-term performance.
