man u are doing a bunch of stuff i thought about doing. ordered the nrg cover online, but after over a month i got no word on shipping i got a refund. at the same time i painted my strut tower cover in favtor z34 silver (thought about going polished for a long time).
btw, you should go with some polished long tubes in your ride. it would look sick with the polished strut tower brace. maybe some injens?
(mine as ref)
I still wanna get a hold of an nrg cover tho. so whenever yours comes in post up some pics! you dont get to see many on z's.
