Paper Gauge?
In the AE TC3 setup guide there is a page that you lay your car on top. You line the side of the car up with one line and there are two other lines, one for each wheel. The wheel lines are at 0 and 2° which are not usefor for front toe out, so I made my own for -.5 and -1.0 degree toe out.
In addition I set the steering with this piece of paper. It is acurate enough, that the car steers down the straightway without trimming the steering on the radio.
I don't use set up wheels for this, the standard Jaco wheel will work.
The first one I made was with hand drafting tools, and it worked fine with no problems. Since then I have drawn up the paper guage using a CAD system. The CAD system and printer are really accurate, but the printer stretchs the paper. On an A size piece of paper, the effect is minimal.
