This Is300 Rear strut bar is a great modification to any IS. It helps get rid of chassis flex by bridging the rear strut towers, creating a stiffer chassis and better handling vehicle. This strut bar is easy to install (with simple hand tools it can be done in less than an hour). A great performance modification for you track stars, as well as a nice show piece for those of you who like to rack up the points at your local showoff.
