I have been using my toe plates for alignments for a little bit. I like it a lot and currently only do it on my garage floor where I have used some 12X12 tile to level the 4 spots that my tires rest. I have marked on my camber plates the two places I move it too to get the 1.5 and 3 degrees of negative camber I use for autocross racing. What I want to know is can I just adjust the toe on site using my toe plates rather then in my garage where I know the floor is flat. I have everything marked so it is relatively easy to get everything pretty close so I would just be checking it after I did my adjustments.
