R1 Concepts 623-02021R RNC Series Drilled Brake Rotor

The R1 Concepts 623-02021R RNC Series Drilled Brake Rotor is a high-performance replacement rotor engineered for drivers who demand improved stopping power and thermal management over stock brake components. R1 Concepts' RNC (Rotor No-Coat) line features a corrosion-resistant, non-coated zinc-washed finish on the hat and edges, keeping the rotor looking clean while the precision-drilled venting holes promote rapid heat dissipation during hard braking.

Key Features:

• Drilled Hole Pattern: Cross-drilled holes channel heat, gas, and debris away from the rotor surface, reducing brake fade under repeated or aggressive braking
• High-Carbon G3000 Cast Iron: Premium metallurgy delivers outstanding durability, reduced vibration, and quieter braking compared to standard rotors
• OE-Style Direct Fit: Bolt-on replacement design requires no modifications for a straightforward installation
• Zinc-Washed Finish: Applied to non-friction surfaces to resist surface rust and improve overall appearance
• Precision Machined: Computer-balanced and machined to tight tolerances to minimize vibration and pedal pulsation
• Slots and Drilled Holes: Optimized venting geometry for street and performance driving applications

The R1 Concepts RNC drilled rotor is designed as a direct OEM replacement, making it ideal for everyday drivers and enthusiasts looking to upgrade their braking system without extensive modifications. Compatible with standard OE-style calipers and brake pads.
