With this tool, every alignment will have the rack in the same place every time, which can save time when doing a quick check of toe after a hard day at the track or on the street. If your steering rack is in the same place for every alignment then the steering wheel will also be in the same place, hence eliminating the need to reset the steering wheel. Every time a toe adjustment is done and the tie rod is moved without the alignment tool, it moves the steering rack, resulting in having to recheck all alignment numbers after each adjustment, resulting in having to set up the alignment equipment after every adjustment.
