+40 with a 205 tire will make you rub on tight turns, guaranteed.
Do at least a +42.
I hate establishing credibility, because it makes me sound conceited, (start sounding like an ass here) but I was suspension moderator and wheels/tires moderator (other forums too) at SHO for 2 years and I've been moderating suspension and ITR forums at hondavision (much better than sho) since it began. Ever heard of "Offset 101"? I wrote it. I also know of many people who have gotten +40 on that generation of civic, and have rubbed.(end sounding like an ass here)
So.....+42-45
