I think your FX would look sweat tucking tire, but since someone offered this point to me about 6 months ago, I will offer it to you.
If you are going to lower your FX more than just getting coils (I have H&R) you will need a camber kit to get it aligned.
That said, if you have some mechanical ability or friends that do, try raising the mount on your struts. You can go ALOT lower without any of the negative consequences.
I looked for the post but I didn't find it.
