Thanks everyone for the input.

I did notice (besides noticing that I wrote "If I wanted to..." in my original post twice. Oops.) that the +2 sizing was actually closer in rolling diameter than the +1 to the original rolling diameter.

Having replaced two wheels and three tires on a previous car (another Audi) with 45-ratio tires on 17" wheels due to crazy-bad L.A. road surfaces, I am somewhat leery of going down that... road again. Inevitable pun, sorry.

Looks like doing the HFP 17s from H & A and some kind of Pilot at 225/45-17 it would be right around $300 a wheel. Wouldn't mind finding some take-off 16"s from an EX. I like the entire wheel program for the 06 Civics except the Hybrid wheels. O' course.

Any HCH drivers/buyers-to-be looking at the upcoming HFP suspension kit? Solely to lower the ride height for better aerodynamics. O' course. the body kit is overkill, but the suspension parts sound tempting...
