R1 Concepts 623-13035L RNC Series Drilled Disc Brake Rotor - Left

The R1 Concepts 623-13035L RNC Series Drilled Brake Rotor is a precision-engineered drilled disc brake rotor designed to deliver consistent, reliable stopping power. This left-side (driver's side) rotor is built to OEM specifications, making it a direct drop-in replacement with no modifications required.

Precision cross-drilled holes improve heat dissipation and ventilation across the rotor's braking surface, helping reduce brake fade during repeated or heavy stopping. The drilled pattern also assists in channeling away gas, dust, and moisture that can accumulate between the pad and rotor face.

Key Features:

• Drilled Design: Cross-drilled holes promote airflow and heat dissipation to reduce brake fade
• G3000 Grade Cast Iron Construction: High-grade iron formulation delivers strength, durability, and consistent performance
• Zinc Coating: Protective zinc finish guards against rust and corrosion, extending rotor life and maintaining clean appearance
• OEM-Matched Specifications: Engineered to match original equipment dimensions for direct bolt-on fitment
• Left Side (Driver's Side): Designed specifically for the left front or rear position as indicated by the "L" suffix in the part number
• Balanced and Precision Machined: Each rotor is precision machined and balanced to minimize vibration and pedal pulsation

The R1 Concepts RNC Series drilled brake rotor is an excellent choice for drivers seeking an upgrade over a standard smooth rotor while maintaining daily-driver reliability. Compatible with both OEM and aftermarket brake pads.
