R1 Concepts 623-54135L RNC Series Drilled & Coated Brake Rotor - Left

The R1 Concepts 623-54135L is a cross-drilled brake rotor from the RNC (R1 Nakamura Coated) Series, engineered for drivers who demand improved braking performance and long-lasting corrosion resistance. This is the left-side rotor, designed as a direct OE replacement with upgraded construction.

The precision cross-drilled holes help dissipate heat and gases that build up during braking, reducing brake fade and improving overall stopping power. The proprietary zinc dichromate coating protects the rotor's hat and non-contact surfaces from rust and corrosion, keeping the rotor looking clean and performing reliably over time.

Key Features:

• Cross-Drilled Design: Enhances heat and gas dissipation for reduced brake fade
• RNC Zinc Dichromate Coating: Corrosion-resistant finish protects non-swept surfaces
• Left-Side Application: Designed specifically for the driver's side (suffix "L")
• Direct OE Replacement: Bolt-on fitment with no modifications required
• G3000 Grade Cast Iron: Premium iron compound for durability and consistent performance
• Computer Balanced: Minimizes vibration and pedal pulsation

The R1 Concepts RNC Series brake rotor is a reliable upgrade over standard OEM rotors, offering improved thermal management and a cleaner appearance. Compatible with OEM and most aftermarket brake pads.
