I am looking at getting some suspension pieces. First i want to get shocks and struts. Was looking at the tokico HP's. Is it worth it to step up to adj one's? My car is mainly street use with some strip time. Next question, is there a big differnce between cheap control arms and expensive one's? And what about subframe connectors? I will def weld them in. With the adj units, can I adj. them to better perform at the strip then return back to street settings? Thanks I just don't want to spend money that I don't have to.
