u own an R34 GT"S"-T? did u mean GT-T?
its quite an expensive venture, obviously youll need bonnet, front bar, skirts, front quarter and rear quarter panels, and rear bar... the wing if u want it, possibly headlights, also possibly tali lights, there has been some debate over this though i know some ppl have done it b4
expect to pay thru the nose for it, id say $10,00 + as a ball park figure including fitament painting etc...
