I am not sure if I want to go 17s or 18s. Maybe you fello fd owners can help me by posting what setup your running with some pics be best. Maybe this can be an official rim thread, I don't believe I seen a rim thread yet. Thanks in advance to all that respond.

 

In regards to stock fenders: 17's are the optimal size for performance. However, in most people's eyes the 18's look better than 17's and they still work great as long as the diameter of the wheel and tire remains the same (as the 17's with optimal tire). 19's IMO are too large for a stock fender FD.

With that said there is already a thread dedicated to what you are asking:

Here's a fitment thread:

I have 18's BTW 18x8.5 +42 (225 tire) upfront and 18x9.5 +40 (255 tire and sometimes 265) in the rear. My setup is not aggressive at all and IMO could use some lower offsets.

 

17 X 9 +48 running 255's all around. Coil-overs but no fender rolling. I was told by the wheel manufacturer that in their database, 265's will clear on the rear of an FD with that wheel/off-set.
I actually prefer 17's for looks, but it's your car. If your interested, I think there are some pictures in the photo album on my profile page.

 

I had 19s on my FD, the ride was fine and the steplip made them look a bit smaller. IMO 18s would be ideal and 17s look too small unless they are a monoblock.

 

Yup I did fid the thread afterwards. But thanks for the reply's guys
