I have a 2007 GT with the stock 18" wheels.
I would like to know any pro's & con's of two different wheels, both will be 18 x 9 with 255 45 tires.
The difference is one has a 34mm offset with 6.3" backspace, the other has a 50mm offset with 6.81" backset.

That off-set difference is normal.

Nearly all cars have a different off-set in front/rear. That tire/wheels combo is no problem what so ever on your ride. The 50mm would go on rear.

All four wheels would be the same front and rear.
One is the SVT Bullitt (50mm) and the other is from American Muscle (34mm).

You will actually probably not be able to install the 50mm up front. I think they will be too far inward. I hate using off-set measurements, can you measure the back-space of the current fronts and compare with proposed 50mm wheels? This will tell you if you have clearance.

The 34mm will fit without an issue, think you will have probs with 50mm set. Besides, the 34mm set will move the wheel about 5/8" outward of the 50mm set and fill the wheel well better, IMO.
