They have about 7" of backspacing on the 9.5" wheels. That would fit under the rear, but the fronts are going to rub on the spindles.
This is exactly the case. Last year when I had my '11 GT, I put its wheels on the Bird when I put the Bird's FR500's on the Stang. The backs were fine, but the fronts rubbed the top of the spindle, or were at least too close for comfort.
