Steering All Over the Place at 55mph+

Man, those things are a Lil Crusty! lol, you can go with the offset bushings I guess to gain even more Caster but I doubt it would be needed, I don't know, @72bluNblu would know more about that tidbit. I want to say some of those come with bushings in them anyhow you could probably get rid of the bushings you got by returning them and offset the cost of the new arms somewhat
