The RS-R Best*i Active Coilover Kit for the Lexus IS 500 is designed to work with your factory AVS (Adaptive Variable Suspension) system—preserving OEM electronic dampening controls while providing fully adjustable ride height and enhanced handling. This system allows you to maintain Lexus's factory ride quality and control features without sacrificing performance or adjustability.
⚙️ AVS-Compatible Performance:
