R1 Concepts 623-03046R RNC Series Drilled Brake Rotor

The R1 Concepts 623-03046R RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver consistent, fade-resistant stopping power. Constructed from high-carbon grey iron, this rotor offers superior thermal conductivity and durability compared to standard OE rotors.

The drilled hole pattern improves heat dissipation and helps evacuate gases and water from the rotor surface, maintaining a clean rotor-to-pad contact area and reducing brake fade during repeated stops. The rotor is computer-balanced and features a non-directional finish on the friction surface for immediate break-in.

Key Features:

• Drilled hole pattern for enhanced heat dissipation and gas venting
• High-carbon grey iron construction for strength and thermal performance
• Computer-balanced to minimize vibration and pulsation
• Corrosion-resistant coating on non-friction surfaces
• Direct OE replacement — no modifications required
• Manufactured to strict dimensional tolerances for proper fit and function
• Part of R1 Concepts' RNC performance rotor lineup

R1 Concepts is a trusted manufacturer of performance brake components. The 623-03046R is engineered as a direct-fit replacement rotor, making installation straightforward with no special tools or modifications needed. Ideal for drivers seeking improved braking performance over standard OE rotors.
