Reference for the fronts:
Moving to Fort Worth
This user's specs:
19x10.5 et 21 front 275/35/19 Nitto Invos
19x12.5 et 33 rear 345/30/19 Nitto Invos
You will need camber adjustment and rolled fenders in front
for the rears, references this page of pix from DPE_G
2015 Nismo Build
his rear specs:
20x11 +0
285/30/20
-2 camber (stock is like 1.7 or something like that)
With rolled fenders and lowering about 1.75 inches you're probably close to fitting
Again though. For perfect fitment, rolled fenders + SPL + alignment = no worries

iBenJAMM1n's 15 Nismo build
iBenJAAM1n ran through multiple wheel setups. He and DPE_G were among the first to do aggressive fitment on the 2015+ nismo
