R1 Concepts 623-54185R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-54185R RNC Series Drilled Brake Rotor delivers reliable stopping performance in a precision-machined, drilled disc design. Engineered to OE fit and dimensional standards, this rotor is a direct bolt-on replacement that also offers an upgrade in thermal management over stock rotors.

R1 Concepts' RNC series rotors feature a cross-drilled pattern that helps dissipate heat rapidly, evacuate gases from the pad-to-rotor interface, and reduce overall brake fade during demanding driving conditions. The result is consistent, confident braking whether you're on the highway or navigating stop-and-go traffic.

Key Features:

• Cross-Drilled Design – Improves heat dissipation and reduces brake fade
• Precision-Machined Finish – Ensures smooth, vibration-free braking performance
• Direct OE Replacement – Bolt-on fitment with no modification required
• Zinc Dichromate Coating – Protects non-braking surfaces from rust and corrosion
• Vented Construction – Promotes airflow between rotor faces for cooler operating temperatures
• Manufacturer Part Number: 623-54185R

Manufactured to strict quality standards, the R1 Concepts RNC rotor is G3000-grade cast iron for durability and long service life. It pairs seamlessly with R1 Concepts brake pads or quality OE-equivalent pads for optimal braking feel and wear characteristics.
