Try getting stuff that enhances both the appearance AND function at the same time. I would hope you want more from your car than impressing kiddies at a show, maybe get some real enjoyment from driving it...
Try these...JDM Type-R guage cluster, some real coilovers, nice wheels, good racing seats from Sparco or MOMO or whoever to compliment the interior and keep you in while driving. Shift knob and steering wheel to match the seats. Then body kit stuff along with stainless engine bolt-ons & exhaust.
