Guys you can pick whatever offset you want. Yes, to get the more concave GTR face you have to go 37 front, but 45 is probably the more conservative setup for the car. 37 will clear any BBK, but you can go 45, 48, 50, and 54. Factory offset is 55.
Rear choices are 45, 35, and 25, even 15 depending on wheel width. 15 will be getting into mexi flush territory.
If you go 17x8 front at 37 and 18x10 rear at 35 you are keeping the track ratio between front and rear nearly the same as stock. You are going out around 20mm in terms of offset and 1" wider of a wheel front and rear. To figure out where your rim edge lands is not hard. 1" is 25.4 mm. Factory rear for example on most NSX's is 17x9. Factory offset is 55. If you go to an offset of 35, you've pushed the center of the wheel inward and the outer edge outwards by 20mm. Same thing as taking a factory wheel and adding a 20mm spacer. If wheel widths were the same, your rim edge would be like factory with a 20mm spacer added (you went from 55 stock to 35 rsII). Now because you have a 1" wider wheel to, going from 9" stock to 10" aftermarket, you are gaining another 25mm. Half of that sits on the inside edge, half on the outside edge. So that is roughly 13mm extra (25.4/2). Now the edge of your wheel has moved out a total of 33mm. 13 of that was from the 0.5" extra you gained on the outer edge of the wheel from it being 1" wider, and 20 of it gained from changing offset from the factory 55 to aftermarket 35.
