R1 Concepts 623-63026L RNC Series Drilled Rear Driver Side Brake Rotor

The R1 Concepts 623-63026L RNC Series Brake Rotor is a cross-drilled, single-piece rear driver-side (left) disc brake rotor engineered for reliable, consistent stopping performance. Manufactured to OEM fitment specifications, this rotor installs without modification and restores proper braking function.

Key Features:

• Cross-Drilled Design: Precision-drilled holes improve heat dissipation and ventilation, reducing brake fade during repeated stops
• G3000 Grade Cast Iron Construction: High-quality cast iron provides the strength, durability, and thermal stability required for safe, long-lasting braking
• Silver Zinc Plated Coating: Protective zinc finish guards against corrosion and rust, extending rotor life and maintaining appearance
• OEM-Spec Fitment: Engineered to match original equipment dimensions for a direct, no-modification installation
• Rear Driver Side (Left): Single rotor — position-specific fitment for the left rear axle position
• Vented Rotor Design: Internal vane structure promotes airflow and rapid heat dissipation for consistent braking under load

The R1 Concepts RNC Series brake rotor is an excellent choice for daily drivers seeking an upgrade over worn OEM rotors. The cross-drilled pattern helps clear brake dust and gas buildup from the pad surface, contributing to more responsive braking performance. Compatible with R1 Concepts brake pad lines for a matched system replacement.
