The KSport Circuit Pro 3 Way Adjustable Coilover Kit is the top of the KSport track-day ladder for the 2000-2005 Lexus IS300. Three independent knobs separate high-speed compression, low-speed compression, and rebound — so you can control how the chassis reacts to curbs, how it settles through a fast sweeper, and how it recovers from a hard braking zone, all without touching the other two axes.
For serious Lexus IS300 track drivers and race teams, the Circuit Pro delivers the setup flexibility you need to get the absolute last tenth out of a lap. Remote reservoirs provide the oil volume and heat capacity required for long sessions, and the monotube design gives the consistent performance that makes your data meaningful. This is a full race coilover you can still dial back for the drive home.
