R1 Concepts 623-58028R RNC Series Cross-Drilled Brake Rotor - Passenger Side

The R1 Concepts 623-58028R RNC Series Drilled Brake Rotor is a direct-fit performance replacement rotor engineered to deliver improved stopping power and thermal management over a standard OEM disc. Part of R1 Concepts' RNC (drilled) rotor lineup, this rotor is precision-machined for a direct OEM-style replacement fit.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote rapid heat dissipation, reduce brake fade under repeated hard stops, and help expel gas and debris from the braking surface
• Silver Zinc Plated Coating: Protects non-braking surfaces from corrosion, extending rotor service life and maintaining clean appearance behind the wheel
• High-Carbon Gray Iron Construction: Provides superior strength, noise dampening, and consistent performance across a wide range of driving conditions
• OEM-Grade Precision Machining: Manufactured to meet or exceed original equipment specifications for a direct bolt-on installation with no modifications required
• Passenger Side (Right): This is a single rotor for the right/passenger side position — sold individually

R1 Concepts rotors are designed for drivers who want a meaningful upgrade from worn OEM hardware without sacrificing daily driveability. The RNC drilled rotor is well-suited for street use and light performance driving, offering a balance of cooling performance, longevity, and clean aesthetics. A proper break-in procedure is recommended after installation to ensure optimal pad transfer and rotor performance.
