I don't see why they wouldn't fit.. The standard 18" wheel size is 18x8" with +35mm offset.. You'll also notice an attached link below from Tire Rack which provides listings for aftermarket wheel/tire size packages for the 2011 Mustang GT.
The list includes 18x9" (front) with 45mm offset along with 18x10.5" (rear) w/38mm offset and 18x10.5" (rear) with 45mm offset.. As long as the offset range for the 18x9" wheel is between +20/+45mm, there shouldn't be any fitment nor clearance issues up front.
For 18x11" sizes, my guess is if the offset is between +35/+52mm, you'll have plenty of clearance in the rear. For my particular application, I run OEM 2007-09 Shelby GT500 wheels in 18x9.5" both front and rear which have +45mm offset and the fitment is spot on paired with 275/40/18" tires.. That being said, if they came off an "03" Cobra/Terminator, they should also fit just fine on your 2011 GT as well.
