ruler, protractor, stick on the rims was an idea. Figured I had to first affix the car to something that would measure off of my true centerline of it and not let it move while I'm checking the toe. Camber I figured I could measure off the posts, but it still would just get me close because I can't see a 1/4 difference on the tape or caliper.comes down to running it on flat surface at 0 on the trim after that.
