R1 Concepts 623-45007R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-45007R RNC Series Drilled Brake Rotor is a performance-grade disc brake rotor engineered for improved stopping power, heat dissipation, and long-term durability. As a direct OE-style replacement with performance upgrades, this rotor is designed to deliver confident, fade-resistant braking in everyday and spirited driving conditions.

The cross-drilled hole pattern is the defining feature of the RNC series, allowing heat, gas, and moisture to escape rapidly from the rotor surface during heavy braking. This venting action helps reduce brake fade, minimizes pad glazing, and keeps operating temperatures in check — particularly during repeated or hard stops. The result is more consistent brake feel and extended component life.

Key Features:

• Cross-Drilled Design: Precision-drilled holes promote rapid heat and gas evacuation, reducing brake fade and improving wet-weather braking performance
• Direct-Fit Replacement: Engineered to match OEM mounting dimensions for a straightforward, no-modification installation
• High-Carbon Gray Iron Construction: Provides superior heat absorption and dissipation compared to standard iron rotors
• Balanced and Precision-Turned: Each rotor is balanced and machined to tight tolerances to minimize vibration and pedal pulsation
• Right-Side Rotor (R): This listing is for the right-side (passenger side) rotor only
• OE-Style Vented Design: Internal vane structure promotes continuous airflow through the rotor for sustained cooling

The R1 Concepts 623-45007R is compatible with standard OEM brake pads and is also an excellent pairing with R1 Concepts' ceramic or semi-metallic brake pad lines for a full performance brake system upgrade. Installation requires no special tools beyond standard brake service equipment.
