R1 Concepts 623-54229R RNC Series Cross-Drilled Disc Brake Rotor

The R1 Concepts 623-54229R is a RNC Series cross-drilled disc brake rotor engineered to deliver dependable stopping performance as a direct OE replacement or performance upgrade. R1 Concepts designs their RNC rotors with precision-drilled holes across the rotor face to promote heat dissipation, reduce brake fade during demanding use, and help expel gas and water from the braking surface for consistent pedal feel.

Key Features:

• Cross-Drilled Design: Strategically placed drill holes reduce rotor surface temperature and minimize brake fade under repeated hard stops
• OE-Matched Fitment: Engineered to match original equipment specifications for a straightforward, hardware-compatible installation
• Corrosion-Resistant Coating: Silver zinc coating applied to non-braking surfaces protects the hub, vanes, and hat from rust and corrosion, extending service life and maintaining appearance
• High-Carbon Gray Iron Construction: Premium casting material provides excellent thermal capacity, vibration dampening, and long rotor life
• Precision Balanced: Each rotor is computer-balanced to minimize vibration and deliver smooth, quiet braking performance
• Direct Replacement: Sold individually; designed for direct bolt-on installation with no modifications required

R1 Concepts is a Los Angeles-based manufacturer with over 20 years of brake engineering expertise, offering one of the most comprehensive brake catalogs in the industry. The RNC Series rotor is an ideal solution for drivers seeking improved thermal performance over a standard smooth rotor without the added complexity of slotting. A proper break-in procedure is recommended upon installation to fully seat the rotor surface with your brake pads.
