R1 Concepts 623-58013R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-58013R is a RNC Series cross-drilled disc brake rotor engineered to deliver consistent, reliable stopping power. Designed as a direct OEM replacement with a performance upgrade, this rotor features precision-drilled holes across the braking surface to promote heat dissipation, reduce brake fade, and help clear water and gas buildup during braking.

Key Features:

• Cross-Drilled Design: Strategically placed holes reduce rotor temperature and improve wet-weather braking performance by channeling water away from the pad contact surface
• Zinc Plating Coating: Protective zinc coating on non-braking surfaces guards against corrosion, rust, and premature deterioration for an extended service life
• OEM-Grade Precision: Machined to meet or exceed original equipment specifications for a direct bolt-on fit with no modifications required
• Balanced Construction: Computer-balanced for smooth, vibration-free operation and reduced brake pedal pulsation
• High-Quality Cast Iron: Premium G3000 specification cast iron construction provides durability and consistent friction characteristics

The R1 Concepts 623-58013R RNC rotor is a single rotor sold individually. It is compatible with standard OEM brake calipers and pads, and is designed for everyday street driving where improved thermal management and corrosion resistance are desired. A proper break-in (bedding) procedure is recommended upon installation for optimal performance and longevity.
