@OX1 - WOW !!! That is the BEST looking Bullitt setup up I've ever seen.
I'd like to copy that set up, if you dont mind, for my 2010 GT - can you clarify a couple things? I got a little confused as to what the specs are for the setup in the pics - also, who makes those wheels? I know several different companies make them - I'm guessing those are American Racing or American Muscle? If you could list the wheel size, offsets, tire sizes I would really appreciate it - that is exactly the look I want but I would like to try to run a square setup using 4 deep dish (like your rears in the pic) if possible - I'd be willing to sacrifice some rear tire width in order to do a square set up with wide deep dish wheels all around THANKS !!
Sorry, you can't get those "grey" Bullitt's for S197's anymore, only for new edge now. But these were the style/company I got them from (I cut down stock stang center caps and glued them in). Pictured (above) is 18 X 10/9 set they used to sell. Tires were 295/40 NT05 in rear and a 255/45 NT555 front.

AM still makes these rims though. They call them anthracite, but they are really silver, with a tiny hint of green/blue to them.

Weird, I just found these too, claims for 05-09, not sure why they would be different than 10-14.

I bought a set of them also for my drag racing setup (10 rear, 8 front). You could have the spokes powder coated a true grey to match what I have. This is what those rims look like (they are the same 18 x 10 with 45 offset as the first AM's I posted about above, so should fit just as easily except for brake caliper clearance, which won't matter unless you have Brembos).
I think a 285/40 (or maybe 45) would fit with no spacers, and be plenty big enough for rear also. Something like this, they are only .2 inches smaller in diameter than stock 14 S197 tire size. .

Funny, I just found this image on AM, looks like just the setup you want.
The downside is these deep dish rims are an absolute nightmare to mount a tire. The deep dish makes the recessed part of rim really far away from outer rim edge. Tends to want to try and rip the bead when putting a stiff summer low profile tire on (see pic below). Luckily, it is easier to get them on than off, but hopefully, when you are taking them off, that means they are shot.
Those rims made me upgrade my tire machine with a bead compression setup instead of trashing inside of rim with crow bars.
