R1 Concepts 623-59002R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-59002R is an RNC Series cross-drilled disc brake rotor engineered to deliver improved stopping performance over a standard OEM replacement rotor. Manufactured to OEM specifications using G3000 grade cast iron, this rotor installs as a direct-fit replacement with no modifications required.

Key Features:

• Cross-Drilled Design: Precision-drilled and countersunk holes reduce rotor surface temperature by dissipating heat buildup, helping to minimize brake fade during demanding stops
• Chamfered Drill Holes: Each hole is chamfered and countersunk to maintain rotor integrity and reduce the risk of stress cracking
• G3000 Cast Iron Construction: Manufactured from G3000 grade cast iron to OEM specifications for consistent durability, stability, and reliable braking performance
• Zinc Plating Coating: Silver zinc plated finish applied to the hat, hub, and vane areas to protect against corrosion and extend rotor service life
• Direct-Fit Installation: Designed to OEM dimensions for a bolt-on replacement — no drilling, grinding, or modification required
• Vented Design: Internal venting promotes airflow and helps manage heat across the rotor face during normal and heavy-use braking

R1 Concepts RNC Series drilled rotors are a solid upgrade for drivers seeking enhanced heat dissipation and a cleaner appearance compared to blank OEM-style rotors. A proper bed-in break-in procedure is recommended upon installation to ensure optimal pad transfer and long-term braking consistency.
