Front End Alignment

Bodyperson said
I think the MODERN alignment shops use equipment with electrical sensors to compensate for any wheel run-out, along with a lot of other things we can not measure without sensors and computers. Seeing you are only doing a two wheel alignment, the little bit of compensation run-out you may experience with your set-up is moot compared to not measuring thrust ,off-set and set-back.
I'm curios about your toe measuring methods and do you have a method for predicting set-back?

Assume this is a test?, but without getting in to a pissing match, let me say that wheel alignments are only as good as the person doing them, whether you are doing it at home with a few $100 dollars worth of equipment or modern alignment shops using $100k worth of equipment. I found this out the hard way with my race car. I now do ALL my own alignments. Just about anything you can measure with a sensor / computer, you can also measure ( and compensate for - if you are inclined to fix it properly ) mechanically. This includes wheel run out, off-set, set back, SAI. Once you have made your rear axle measurements ( no off-set or set back ), a 4 wheel alignment is pretty much a moog point - no need to measure off of something that you already know is sitting in there straight. A 2 wheel alignment will work just fine. Attached pic is of my toe gauge. I usually shoot for 1/16" in for the street. Race car = 0.
