The man wants MORE caster. How about this idea?

Not trying to be controversial, but is any modification DOT approved on anybody’s car here?

Top A arm is a pretty low tech piece of stamped steel. Given some reasonable welding skills and a little bit of reinforcing, this seems like a great idea for us cheapskates. Like just about anything, a skilled guy can make it work and an unskilled guy can’t.
That’s also a valid point. And it depends on which inspection station you use. If you go to the places who do it “the mostly right way” that put a Jack under your lower control arm and lift the front end and check parts for slop, they’re probably going to have questions about seeing welds on the upper control arm. I will agree that it shouldn’t be an issue if done properly. Those same shops here get a lot of business plating frames and rebuilding front ends, too! My friend who’s a former commission mechanic was licensed to do state inspections was usually on the frame repairs. If you watch “just rolled in”, he was usually living the nightmare. That and the mine and gas well service trucks with a wheelbarrow of dried mud caked on underneath them.
