R1 Concepts 623-59049R RNC Series Drilled Disc Brake Rotor

The R1 Concepts 623-59049R is a premium RNC Series drilled disc brake rotor engineered for improved stopping performance and heat dissipation. Manufactured from high-carbon grey iron, this rotor delivers consistent, fade-resistant braking under a wide range of driving conditions.

Key Features:

• Drilled Design: Precision cross-drilled holes reduce heat buildup, evacuate gas and debris, and help keep the rotor surface clean for consistent pad contact
• High-Carbon Grey Iron Construction: Provides superior strength, reduced noise, and extended rotor life compared to standard cast iron
• OEM-Style Fitment: Engineered to meet or exceed OEM specifications for a direct, no-modification installation
• Zinc Dichromate Coating: Protective coating on non-contact surfaces resists corrosion and provides a clean, finished appearance out of the box
• Balanced & Tested: Each rotor is precision-balanced and tested to minimize vibration and ensure smooth, quiet braking performance
• Direct Replacement: Designed as a direct OEM replacement, compatible with stock brake calipers and hardware

The R1 Concepts RNC Series is ideal for drivers seeking a reliable, performance-oriented upgrade over worn OEM rotors. This rotor pairs well with R1 Concepts' eLine or RLine brake pad compounds for a complete brake system refresh.
