I really want to lower my GT with a set of sport springs, but I'm wondering if I really need the camber adjusters and the control arm relocation kit Steeda is hawking. I like my 17" chrome Ford Bullet rims so I'm not dumping them to buy their X5 ball joint which requires an 18" rim. Will I regret it down the road if I just do the springs and skip the extra parts?

Thanks for any input!
