R1 Concepts 623-32020R RNC Series Drilled Brake Rotor

The R1 Concepts 623-32020R is a cross-drilled disc brake rotor from R1 Concepts' RNC Series, engineered to deliver enhanced stopping performance over standard OEM rotors. Manufactured from premium G3000 grade cast iron, this rotor is precision-machined to meet or exceed OEM specifications for a direct-fit, no-modification installation.

Key Features:

• Cross-Drilled Design: Precision-drilled holes are countersunk to maximize heat dissipation, reduce rotor temperature, and help prevent brake fade during demanding driving conditions
• G3000 Grade Cast Iron Construction: High-quality iron formulation delivers consistent braking performance, durability, and long service life
• Zinc Plated Coating: Corrosion-resistant zinc finish protects the rotor hub and vanes from rust, extending rotor life and maintaining appearance
• OEM-Spec Direct Fit: Machined to factory specifications for straightforward installation without modifications
• Balanced and Tested: Each rotor is precision balanced to minimize vibration and pedal pulsation

R1 Concepts rotors are designed for street and performance driving applications where improved thermal management and braking response are desired. Always replace brake pads when installing new rotors and follow the recommended bed-in procedure for optimal performance.
