So I'm looking at getting ZZP control arms but have a question about them. Living in Buffalo I have to deal with rust. Will these rust through being hollow kinda like the stock sway bars? I don't want to spend a lot of money on them and then have to replace them in a few years. Also I've seen threads where people were having trouble with them breaking. They were old threads and I think the problem has since been fixed but I just want to double check.
