you want an easy answer? get 34 GTR rims. they are strong, light(ish), forged, made by BBS, easy to find (if you want a 5th one as spare, or to replace a damaged one), they hold their value, they keep the original GTR theme going, and they look sweet. they are a good size being 18X9 +30 and if you like you can run some 10mm spacers to help them fill out the guards a little more, but they look fine as is too. they do look really good on a white GTR. the dark silver/grey wheel colour is a great contrast against the white. bronze wheels look pretty average on a white car. they are more suited to black/grey/red GTRs.
