The first question I would ask is what vehicle did the wheels come off of originally?
Second, I would ask, what is the bolt pattern of that vehicle?
Third, can you find "spacers" or "adapters" that allow you to run that lug pattern on our thunderbirds?
Fourth, (because the other questions simply answer if they will bolt on) is what is the backspacing of these wheels you are looking to run? The reason I ask this is because the MN12 platform, and most all modern passenger vehicles (save for some trucks and SUV's) have a moderate to high positive offset (backspace 60-90% width of the wheel) which normally means the hubs are further out on the vehicle and the wheels themselves extend further inwards toward the car than out and away from the hub. Older wheels have a tendency of having a low positive, zero, or negative offset (backspace 35-55% width of the wheel) and stick out very far from the hub. Knowing whether they will bolt on
and whether they will fit
is the difference between this:
The simple answer, without going into too much detail, is that old style wheels, plus the width of adapters will make your car look like the Toyota Previa posted above. If you can find some old school wheels you like that have a high or moderate positive offset (+30-+50mm) or large backspace (75-90% width of wheel) then it should look more like the sexy T-Bird posted above.
