I have 18s and love 'em...
OP, you did not say what your suspension mods are. If it's stock, I'd go with the 18s. If it's dropped, using Eibach springs, I'd still go 18.
The only way for you to do this right, is to see pics in the wheel thread and decide on the stance you want. Find out what sizes/offsets are being used and go from there.
This is sounding like you're going to order something that you may end up unhappy with.
Here's a link to mine... 18x8.5 front, 18x9.5 rears (35 offset all around)... Eibach springs/Tokico struts.
Good luck!
