R1 Concepts 623-21051L RNC Series Drilled Brake Rotor

The R1 Concepts 623-21051L RNC Series Drilled Brake Rotor is a precision-engineered replacement rotor designed to deliver consistent stopping power and improved thermal performance. The drilled design promotes heat dissipation and helps evacuate water, dust, and gas from the rotor surface, reducing brake fade during demanding driving conditions.

Key Features:

• Drilled Pattern: Cross-drilled holes improve heat dissipation and reduce rotor surface temperature under heavy braking
• OE-Style Direct Fit: Engineered as a direct replacement for a hassle-free installation with no modifications required
• High-Quality Cast Iron Construction: Premium G3000 metallurgy specification for long-lasting durability and consistent performance
• Precision Balanced: Each rotor is precision-machined and balanced to minimize vibration and pedal pulsation
• Corrosion-Resistant Coating: Protective coating on non-braking surfaces helps resist rust and corrosion during storage and initial use
• R1 Concepts RNC Series: Part of R1 Concepts' entry-level performance rotor lineup offering an upgrade over plain OEM rotors

The R1 Concepts 623-21051L is sold as a single rotor (left side). It is a reliable upgrade for drivers seeking improved braking performance and rotor longevity over standard factory replacements.
