The "2G Bar." Would this make that much of a difference if I use this on the front of my Camaro. I would be bolting it on as my subframe is painted allready so welding it is out the window. It's only $119, is it worth it? Can someone give me an idea of how it works or is it basically just like having an extra brace to prevent twisting?
