Correct offset?

[jr_ss]

Alright, I know this probably gets asked a crap load of times, but I can't find anything on an offset chart for different sized wheels for our cars . I know the S14 has 6.5" rims with a +40mm offset. I was currently looking at some wheels that were designed to fit the 350z, they are 18x8.5 w/ a +25 and 18x9.5 w/ a +30. Now what I want to know is, will these wheels be sticking out from underneath the wheel wells, or will they be sitting flush with the wheel wells? If they are flushed, I don't mind so much as the fenders can be rolled alittle to give me a few mm. But, I however don't want them to stick so far out that even if I roll they won't tuck .

Thanks for your time guys.

They'll fit on an S14 easily with just a roll.
