Tire sizing...

kenchan

for stock height i would do no less than ET35
my nismo's are ET40 or ET41 or something 9.5" width. they are imho perfect for stock height on base.

if lowered you can go lower ET..

Rusty

My front is 19x9.5, +25 with 275/35-19 PSS. Stock height was about perfect. My camber now is -2. So the top of the tire is in a little bit. Still at stock height.

More camber would be lovely, but that costs $700 for the SPL control arms.

I'm at stock height and cannot lower my Daily Driver.

Interestingly, I'm dealing with the same issue in deciding on a set of aftermarket wheels. I agree with Kenchan in terms of the offset, but coming at it from a non-Nismo perspective. The offset on the front stock 19 x 9.0 Ray wheels is +47. I'm not sure of the exact gap between the wheel and the outside of the front fender, but it appears to be around 20 mm based on what I've seen and read. Others can correct me if I'm wrong. With a 9.5" wide wheel, about 5 mm of the gap will be taken up by the added width of the wheel over stock, leaving about 15 mm to spare before the wheel begins to poke ... meaning that you should be looking at an offset of no less than 30-35(i.e., 47-15) if you want to avoid any significant poke. What surprises me is that lots of owners run Volk TE37 SLs with a +22 offset with oversized tires (255/40/R19) on the front apparently without a lot of poke, even at stock height. Bottom line is that I'm still not certain what the ideal offset for the front wheels should be to avoid poke ... but it appears to be +30 mm or above when you're running 9.5" wheels. Others can weigh-in with opinions and pics based on their experience.
