I too got 17" wheels and some people thought they were 16" since the tire size is now 215 /45 17, unlike the older Civic's with 215/40 17. I do wish I did go for 18"ers, but I'm happy with my 17"ers. (see them in the Member's gallery)
I say go fo 18" and lose the white wheels (don't like white on black). Get gun metal in color or regular grey (something like miamijdm).
