Best Spacers size for Nismo with Swift Springs

elvturbo

The general census is that if you want to be flush as possible to the fender, but if you want to still get the stock alignment, tires, wheels width, using Swift springs; Then you should have a spacer setup of 15mm-Front and 20mm-Rear or at least 15mm all around, Right?

But if you plan or prefer to have wider tires in the future, then you should only get 15mm front and back, to leave room for the bigger tire width and still get stock alignment, am I right, or you think it should only be 15mm all around period, to have a better ride with the nismo specs? Thanks!
