Well: I've been auto crossing my classic roadster for a few years now and used to have to get the alignment redone every few races. What I found was the upper A-arms were moving in the adjustment slots. It was worse on rough courses. So I went to adjustable tubular upper A-arms and welded washers around the mounting bolts to hold them in place. The adjustability in the A-arms allows me to make changes to the alignment when needed. The rest of the time everything stays where I put it...
