R1 Concepts 623-31015L RNC Series Drilled Brake Rotor

The R1 Concepts 623-31015L is a precision-engineered drilled brake rotor from R1 Concepts' RNC (Replacement) Series, designed to deliver reliable stopping performance as a direct OEM-style replacement with a performance-oriented drilled pattern. This left-side rotor is manufactured to meet or exceed original equipment specifications, making it a straightforward upgrade or replacement for worn factory rotors.

The cross-drilled design promotes consistent heat dissipation during braking, helping to reduce brake fade under normal to spirited driving conditions. The rotor's vented construction further aids in cooling, while the drilled holes allow for the outgassing of heat and gases that can build up between the pad and rotor surface.

Key Features:

• Cross-Drilled Pattern: Improves heat dissipation and reduces brake fade
• Vented Construction: Internal vanes channel airflow to keep rotor temperatures in check
• Direct OE Replacement: Bolt-on fitment with no modifications required
• Left Side (Driver Side): Designed specifically for the left-side position
• Corrosion-Resistant Finish: Protective coating helps prevent rust during storage and initial use
• Precision Machined: Manufactured to tight tolerances for smooth, vibration-free braking
• MPN: 623-31015L

R1 Concepts rotors are manufactured using high-quality gray iron and undergo rigorous quality control to ensure consistent performance and longevity. Whether replacing a worn rotor or upgrading from a plain rotor, the 623-31015L provides a reliable, performance-ready solution.
