R1 Concepts 623-03025L RNC Series Drilled Brake Rotor - Left

The R1 Concepts 623-03025L RNC Series Drilled Brake Rotor is a direct-fit replacement rotor engineered to restore and improve braking performance. The drilled hole pattern across the rotor face promotes heat dissipation, helps evacuate gases and moisture from the braking surface, and reduces overall rotor weight — all contributing to more consistent, fade-resistant stops.

Key Features:

• Drilled Design: Cross-drilled holes improve heat venting and help keep the rotor and pad surface clear during repeated braking cycles
• Direct OE Replacement: Engineered to OEM specifications for a bolt-on fit with no modifications required
• Left-Side Application: Designed specifically for the driver-side (left) position
• G3000 Metallurgy: Cast from premium G3000 gray iron for durability, consistent friction surface, and long service life
• Corrosion-Resistant Coating: Non-braking surfaces feature a zinc or e-coating finish to resist rust and maintain a clean appearance
• Precision Balanced: Computer-balanced to minimize vibration, pedal pulsation, and noise during operation

The R1 Concepts RNC line delivers reliable everyday braking performance and is an ideal choice for drivers seeking a quality OE-style upgrade with the added benefit of a drilled surface. Sold individually as a single left-side rotor.
