Lefties have rights, too!
I replaced my upper control arms a couple months ago and decided after much input from PW AWE and SRS to change the distance from the OEM 47mm setting to something more inline with my lowered suspension. While I couldn't get anyone besides Herman H to comitt to a number I decided to use 44mm. The problem was how to do this in a accurate manner than I guessed earlier. My car is low enough that this is no way one can tighten the bolts on the UCAs once the wheel is put back on. So I decided to make my own jig. Here is what I came up with. I used a piece of 16 ga steel screwed onto an aluminum right angle. Now I can adjust the distance for the UCAs and measure the length exactly. Not very professional looking but at least I can make very accurate adjustments.
