18's on a 370z

I'm looking at 18" SSR GTV02s and I've settled on 9.5" for the front and 10.5" in for the rear. I made notes while reading through this thread, as well as others, and I think I should go with a 35mm offset in the front (22mm is also an option) and a 15mm offset in the rear. I am on Swift springs, with SPL rear camber arms and lock out bolts. I would like to be near flush. No poke at all. Will these offsets get me what I'm looking for?

Also, regarding tires, I'm considering 245/45 in the front and 275/40 in the rear, as these sizes would keep the overall diameter close to stock, as well as the sidewall height. I'd like to go wider, especially in the rear, but then it just starts throwing things out of whack. Thoughts?

All that noted, I really appreciate anyone sharing their advice and feedback. I'd like to go ahead and make my purchase soon.

went with 275 in the front which I think may be the whole issue, but would like insight before changing out the tires

Thanks in advance!

Sorry for late response my friend! Well i think your problem is the front tires... with the setup that i have 255/40 works perfect and i dont have any rubbing issue anyway i think for my next setup i would go with 265 front tires if i found here in PR loool!

You could also try running some negative camber too. I barely rub on the street with a 10.5 in +20 wheel with a 285 tire. Now that I rolled the fenders I dont rub at all. Only on a couple corners on the tracks.

18x10 (+12 offset) on the rear i have 285/40/18 and it fits perfectly.
