This tool was developed by the TMS race crew for multiple applications, such as centering the steering rack, centering the steering wheel, and attaining repeatable alignments. This results in significant time savings when doing street or track suspension setups. Works on E46 3 series including E46 M3, 325i, 325Ci, 328i, 328Ci, 330i & 330ci (including ZHP).

A centered steering rack prevents handling issues such as uneven bump steer, inconsistent steering resistance and unequal turning radius left to right. 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. If you have ever used strings to set up your car you know how much having to restring the car can slow you down. If you are like us at TMS, you want your E46 perfect every time, and you want to achieve perfection as quickly as possible.
