In your case with a stock suspension you should be perfectly fine out back with the more common 6.5" BS 17x10.5 or 18x10 wheels so long as you keep fox length axles.
18x9 Saleens will fit perfectly front and rear with out any modifications. Though you may need to run a 245 tire up front in order to keep the tire from rubbing the strut. A 275 tire on a 9" wheel depending on your alignment may require the need for a 1/2" wheel spacer. I have seen some wheels clear the strut with out a spacer while on others rub the plastic top dust cover on the strut tube,.. and have a tendency to rub the fender liner and lower control arm during tight turns. If your car is lowered then I would definitely stay with a 245 tire up front. The 87 - 90 cars have a smaller front fender wheel opening,.. where the 91 - 93 cars have a larger wheel opening in the front. The 91 - 93 5.0 cars came with 16" Pony wheels and needed the clearance. The 87 - 90 cars had the 15x7 wheels with only 225 profile tires stock and didnt need the clearance.

 

But not the bilble!

I was going to let it go but f*ck it.
Not picking on me? So are you calling me a liar Tommy? WTF man?

Hey,The '94-98 cars rear axle shafts are .75" longer than the stock axles on the '87-93 cars
The '99+ V6/GTs are even longer at about 1.4x"

I used 5 lug fox length with SN95 calipers on the rear, with special brackets that held the calipers on the stock length location fox axles.
I also used the longer SN95 axles on another coupe so I can get the correct offset rim. On the Corral there are guys running 315's on SN95 axles and a 10.5 rim with the correct offset.

 

I covered most of that already.

Q: With SN95 axles and 10.5 wheel then the BS should be 7" correct? I have seen 10" wheels listed with 7" BS. Centerline makes them. I wondered what their purpose was for.

The only thing with that kind of offset is that you wouldnt really get that 'deep dish' look that really sets 10.5 inch wheels off IMO.

not trying to get shit going.not sure about the fox body but i know on the 94-98 yes coilovers give you more.on my 95GT the tires would hit.now on my 94 cobra with coilovers they dont hit. my wheels are 325/50/15

 

yes you did Jim, but you said the SN95 axles are 1.35 on each side and they are not. They are only about .75 each side. The 99 and up are the longer ones.

sorry dont know the offset, forgot. When I did it, I did a search on the corral under 315's

 

What do they hit? The springs or the inner fender?
Chassis wise SN95 cars are for the sake of argument nothing but a fox body in different sheet metal. From the firewall down they are nearly identical. The SN95's track wider due to wider a-arms and axles. But everything from k-members and suspension components all interchange.

The springs on coil overs (If you used a kit that puts them in the stock shock location) will intrude slightly on the wheel well taking about 1/2". With this type of set up you cant possibly gain any room. Look at the pic I posted showing the wheel to spring clearance. SN95 use the same mount location.

I apologize. I meant roughly 1 3/4 for both sides. Not 1.35". 1.5" in total is correct. I dont know why I typed that.

I didnt mention the difference for the 99 - 04. Though I should have. The 99 - 04 axle housings are wider and axles are even wider then the 94 - 98. I used to know exactly how much, but right now it has slipped my mind. I guess I'm getting senile already. The 94 - 98 axle housings are the same width as the fox housings. Only the axles make them wider.

Supposed to be able to just take the caliper brackets from the SN95 cars and flip them to work with fox length axles. I havent tried this personally,.. though I am contemplating it with my 93 when I get it back. I think drum brakes will look a little out of place with 18" wheels. I was trying to avoid it because I didnt want to change my master cylinder and proportioning valve. But if your going to do it may as well do it right.
