Product Details

The R1 Concepts 623-54228L RNC Series Drilled Brake Rotor is a direct-fit replacement rotor engineered to deliver confident stopping performance. Designed as a left-side (driver-side) rotor, it slots into place using OEM mounting points for a straightforward installation without modification.

R1 Concepts' cross-drilled design improves heat dissipation during heavy braking, reduces brake fade, and helps expel gas and debris from the rotor surface — keeping the pad-to-rotor contact area clean and consistent. A silver zinc dichromate coating protects the non-braking surfaces from rust and corrosion, extending the rotor's service life and maintaining a clean appearance behind the wheel.

Key Features:

  • Cross-drilled rotor design for improved heat ventilation and fade resistance
  • Silver zinc dichromate coating on hat and vanes for corrosion protection
  • Left/driver-side fitment (suffix "L")
  • Direct OEM replacement — no modifications required
  • Manufactured to strict dimensional tolerances for proper pad contact and minimal runout
  • Vented rotor construction for continuous airflow and thermal management

R1 Concepts rotors are balanced and finish-machined to minimize vibration and pedal pulsation. The RNC series is engineered for drivers seeking an upgrade over a standard blank rotor, offering the benefits of drilled performance at an accessible price point.

With the outdated vent system in my motorhome, these new vents should really do the trick.
