I felt the same way when I got my Accord...but I'm I'll tell you...
Drop you car first. Then you will have a better idea of what wheels will look good, fit, etc. Plus...driving around with 18's with no drop looks wack.
Then go for 18's if you want bigger wheels. 17's won't look big enough for you on 6th and 7th gens. I have a 40 series tire, and it rides smooth. Just firm enough.
I guess just enjoy your car for now until some suspension components come out for it (if they aren't already out

).
Congrats on the new car, welcome to the board, and I'm jealous of your leather interior.
