R1 Concepts 623-58038R RNC Series Cross-Drilled Brake Rotor

The R1 Concepts 623-58038R is a cross-drilled performance brake rotor from R1 Concepts' RNC Series, engineered to deliver improved stopping power, enhanced heat dissipation, and superior corrosion resistance over standard OEM rotors. Precision-machined to OEM specifications, this direct-fit replacement requires no modifications for installation.

Key Features:

• Cross-Drilled Design: Precision-drilled and chamfered holes reduce rotor operating temperature and help evacuate gas and debris from the braking surface, improving pad bite and overall stopping performance
• Countersunk Drill Holes: Chamfered and countersunk holes help prevent stress cracking for long-term durability
• G3000 Grade Cast Iron Construction: High-quality cast iron provides consistent, fade-resistant braking performance across a wide range of temperatures and driving conditions
• Zinc Protective Coating: A silver zinc-plated finish protects the non-braking surfaces from corrosion, maintaining appearance and extending rotor life
• Direct OEM Fit: Manufactured to factory specifications for a bolt-on installation with no drilling, cutting, or modification required
• Vented Design: Internal vane structure promotes continuous airflow to dissipate heat and reduce brake fade during sustained or heavy braking

The R1 Concepts 623-58038R is well-suited for daily street driving, light performance use, and drivers looking to upgrade from stock rotors without sacrificing ride comfort. Sold individually — confirm quantity needed for your application.
