I'd like to know this as well since I plan on doing my ucabs and checking my measurements while I'm in there.pleasefixitup wrote:perhaps I got some "misinformation"
how do you do it with a set of freeplates and tape measure?
Alignment woes. I don't believe these knuckleheads!

The same way we do it at the race track without freeplates and with a tape measure. We first find a hard flat level surface (At Road America, there are a few former concrete scale pads where tech is no longer done.) and we roll the car onto it. Measure the distance between the same corresponding grooves on the front and rear of the front tires.* [Assuming you have the tie rod ends loose enough to adjust:] Then you set the toe where you want it by using the difference between the two. After each adjustment, roll the car a few feet forward, then back, to compensate for the lack of a freeplate, until your measurement is where you want it. If you want your steering wheel to remain 'straight', do all your adjustment on one side, then back it off by half (If it took 2 turns, back up one turn.) and make the same half adjustment to the other side to keep the wheel where it started out. You usually want from 1/8" in to 1/8" out, depending on what you're doing (autocrossing or high speed driving). You'll never be dreadfully off if you just set it at zero (same measurement front and rear).pleasefixitup wrote:perhaps I got some "misinformation"

* This should be as close to the horizontal centers of the tires as possible, but since this isn't awfully precise, close is usually good enough. You can always reset it in a matter of minutes if it feels wrong.
