I have an '01 GT currently sitting on 17x9s. I'm a junior in high school and I don't have money to upgrade to 18s at the moment, eventually I will. Anyways, the wheel gap (both vertical and horizontal is hideous). I have a bad bushing in my rear driver's side upper control arm (that's a mouthful) and I'm getting those replaced because it squeaks like a mfer. I'll be throwing on wheel spacers as well when I do that. I'll be lowering it next spring, do I go with coilovers or springs and shocks? Cons and benefits of both?
