will these fit front and rear?

http://www.stangmods.com/20-x10-FR50...ng-p/00821.htm

i usually don't see 10" fronts which is why i'm asking. the other available size is 20"x 8.5 though 8.5 is a bit too small in the front to go with 10" rears, am i right?

 

It all depends on the backspacing or offset of the rims.
A specification I dont see listed.

Dont know, it does not state the backspacing, a required dimention
when determining wheel fitment.
But it does feature FREE SHIPPING but not the wheel specifics....

 

10"s up front does seem kind of wide for a front

 

Not if they have correct offset to match the 10" width.
I dont remember seeing any S197s with 10" wide 20s on the front.
I would do the 8.5" wide on the front.

 

true, but i meant more for looks; in my head, picturing anything wider than 9's would weird... and unless are cars were fwd or awd, it would be kind of pointless to have that much tire out front, imo

 

ok sweet. i was thinking 9 too but 8.5 is the only one they got so it'll have to do.

 

10's are stretching it a bit for the fronts IMO, but keep in mind that the GT500 stock wheels come from Ford with 9.5's all the way around with 255/45 front & 285/40 rear for tires.

 

well i don't know anything about offset and all that which is why i'm posting this.

 

I have the 18x8.5s on the front with 255/45-18s on them with a 50mm
offset. I am unaware what the offset is for the GT500s 9.5" wide rims
but it probable puts 1/2 inch towards the inside and 1/2 inch towards
the outside and much bigger steering stops and a much larger turning
radius.

the GT500's have a 45mm offset
