Description
For 2021+ Lexus IS350 RWD / AVS (IS350), the Best-i Active package addresses a common problem with conventional coilovers: loss of factory electronic damper control. RS-R engineers the Active line so the supported OE control system can remain part of the suspension setup.
Why Choose RS-R Best-i Active?
Best-i Active combines RS-R's height-adjustable Best-i architecture with compatibility for supported factory electronic damper-control systems. On the correct application, the goal is to retain the vehicle's factory control strategy while adding aftermarket ride-height and damper tuning capability.

Before Ordering
Electronic-damper compatibility is application-specific. Confirm the exact part number and vehicle equipment before ordering; do not assume every trim with electronic damping uses the same RS-R kit. This listing is application-specific to the stated drivetrain/trim (RWD / AVS); verify that detail rather than ordering by model year alone.
