Staggered or square stance..

I love the way staggered setups look. Mine weren't available in the size I wanted. Square setup has some advantages though like tire rotation and if you ever have a blow out you can swap a front to the rear. I did something a little different. 255s on the front and 275s on 19x10s all around.

Same reasons I went back to square setup, although I do like the look of staggered setups a bit more..

Run the 285 square. Staggered fitment is a waste of time in my mind unless it's a drag car.
Personally I like a 275 on a 10 inch wide wheel, it looks very "supercar" and they are affordable in any wheel diameter.

I run 275/35/20 square on 9.5" width wheel with 45mm offset.. They have more than a wide enough stance and height for my particular application purposes.. No complaints at all.
305's in rear is very sexy.. but cost is crazy.
I do enjoy taking it to the track on
occassion but its mainly my weekend car. 275 all around makes sense cost wise.

Staggered has more benefit for straight line performance. You can go a lot lighter up front with a narrower wheel/tire, plus it will have less rolling resistance. Then you can go as big as needed in the rear for traction. Square your max width is limited by what fits up front. Auto-X guys will tell you a square setup handles better, in addition to the other benefits mentioned.
I have a 285 and 305 staggered setup, but I'll probably switch to a 295 or 285 square setup

285 square here. Handles awesome but a lot of tire noise.
I run 285/40/18 front, 305/40/18 rear on 18x9.5 wheels all around.
Love the handling and overall look
I've run a square 275/40/18 set-up on these same wheels also, before the blower went on, and that looked and handled great.
I've also run 275/40/19 front on 19x10 with 305/35/20 rear on 20x10's, and my last set-up was 20x10's all around with 275/35/20 fronts and 305/35/20 rears.
Always looking for my next set of wheels, haha.

running 275/40R18 here and very happy
On these 10+ cars, you really can't see any stagger.... unless you are lying on your stomach, in front of the car, esp with the front lowered 1/2". 285 square is superb, so is 275 square. Typ a price jump when going from 275's to 285's. You can rotate with any square setup of course. Use too much stagger, and the car will have more of a tendency to under steer..which can be tuned out. If its a DD street car/ hwy cruiser, and loads of hp / tq / blower, then a wider rear, like a 305 makes sense...with a 285 front.
The OP has a 2010 GT, black, same as mine. Currently I use a 285-40-18 rear..and a 275-40-18 front, all 4 on 18 x 10 rims..and all 4 are ET-45. That puts the rears barely tucked inside the rear wheel well, with a tiny bit of sidewall sticking out, like 1-2 mm. That's with the WL watts link tweaked correctly.
I used steeda HD adjustable camber upper strut mounts, with the camber maxed out to aprx 1.9 degrees. That puts the front 275's well inside the tops of each wheel well. These cars handle better with some neg camber on the fronts. They brake + handle real good with either a 275/285 front.
Wider tires, + correct ET, increases the outside to outside track at both ends of the car. That's about as good as it gets. I have zero issues with tram lining, but forget what the toe is set to. I can't really hear any tire noise with the LT's, even at low rpm's... or coasting downhill, with eng off. (I do that once in a while, late at night, so I don't wake up neighbours)

Unless you're running skinnies up front for drag racing or have the rear tubbed to run something crazy like 345s back there, I see zero benefits to a staggered setup.
From a handling perspective, the S197 chassis needs all the front tire it can get. And from a straight-line perspective, the difference in ET between a 255 and 305 on the front is going to be negligible, unless you're chasing that last tenth.

285/30-20 on deep concave 20x10" square setup.
DiMora put MPSS 335-30-18's on 18 x 11.5" wide rims on his 08. No tubbing required. He could also put a 345 DR back there. http://www.s197forum.com/threads/dimoras-widened-weldcraft-wheels-operation-steamroller.81269/ Dust cover on rear shocks removed + bump stop excess metal removed.
A 315 on a 20 x 11 rim will fit the rears easily. A buddy did that on his 2012... no mods required.
A 305 square setup is very doable. Apex offers that with their 18 x 11 and also 19 x 11 EC-7 wheels.
Spacer used on the front + longer front studs. ( then it can be rotated). On paper, a 305 square setup is more than optimum. A 315 rear / 305 front would also work... and wide, for a staggered setup. Apex is a sponsor on S197, and has loads of pix of the 305 ( and also 295) square setup.
Several will use a 295 square arrangement. http://www.s197forum.com/threads/►-apex-ec-7-mustang-wheels.133341/#post-2415550
2 years ago, I was using 255-40-18 on 18 x 9 front rims..worked good. Then swapped the 255 rubber with my spare 275-40-18 rubber. This is on the fronts. Bad move. I did not like the way the front end felt, rubbery, un responsive etc. Replaced the 18 x 9 front rims with 18 x 10 front rims. Huge difference in handling + responsiveness. A 275-40-18 on a 9" rim will work on the rears, but I did not like that combo on the fronts.
If the OP just wants some wider rims + tires for street use, and keeping it simple, without going over the top with $$, 10" wide rims + either 275 or 285 square setup is ample, and allows for rotating. No spacers required, nor longer studs. Oem studs will work just fine. Typ ET for 10" rims is 42mm. (max of 45mm..and a min of 40mm).

Mounting a 275 series (NT555) tire on the 9" wheel was much easier than I expected. And I've mounted some tires in my life! I have a harder time mounting/dismounting 245/45/17's on 9" wheels. (fox body) Handling wise, my only issue with the 275's is coming to a stop on a road that has developed ruts at stop signs and lights. The front end can wander a bit. I agree though, the math says 9" wheel is not the ideal size for a 275 tire. In this case, I have to disagree with the "math".

I went square on my '09 GT500 for the sake of rotation purposes. Running 275/40/18's all around now. Good compromise over the OEM staggered set-up IMHO however, the wider tires up front do make the steering a touch heavier.
