Getting new rims with taxes!!

:thumbup:
Was going to get 17, but the way everyone talks on HAN, i'm going with 16".
This wheel
and falken azenis 215/45/16. Running now nitto 215/40/16. Still have a 2 finger gap all around. The tires is only .7 inches taller, but what offset would i need. What's standard for civic? I think 40.
