Welldone on the purchase!
Just to clarify, is the RB26 stroked to a 2.8lt along with aftermarket turbos?
I'd stick to the Nismo LMGT4 wheels you have and in that Bronze colour too! But just go wider and more aggressive offset.
Millennium Jade and Bronze give you the clean look.
And it being a Nur (bit more of a collectors item) I'd keep the Nissan / Nismo theme going through it.
If it was me, I'd get the same wheels / colour but go for a 18 x 10.5 +15 or +12 and test fit that.
^^ TE37 SL 19 x 10.5 +12, but from memory the previous owner of that car ran a spacer at the rears for a bit of poke.
If you went the TE37 SL or a Black set of Nismo LMGT4's, it'd give you the tough look.
