Im in the hunt for some nice rear control arms, both uppers and lowers. Just need boxed lowers and adjustable uppers. I found a set of both boxed and adjustables through both companies. Ill end up spending 200 more bucks through metco but to me it sounds like there alot stronger being billet and all. I know alot of guys use UMI and they work well. Ill be doing polyurethane bushings that are included. Whats your guys opinions?
