For your front clip, I'm not sure if I can explain it well enough, but I ran into the same thing once when putting it back on...
There are flat wide tabs on the bumper cover that go under the header panel, under the headlights basically. If they are on top of the header panel piece, the bumper won't slid back all the way and push out like it looks like on yours, and did on mine till I corrected it...
Your car definately looks cool layed out like that
now its 25.4 stock is 26.4(I think) I went with 255/45/16 instead of 225/60/16
