Does anyone know if wheels with 5x4.5 lug pattern (like mustang wheels) could fit on our cars, i believe thats what a spacer is for but im not sure and how much do the spacers cost(if that is what you need)

 

you need a 5x4.75 wheel

is the the 'bullit' style wheel you are interested in? because they can be found with our bolt pattern now

 

There are "conversion" type adapters that allow you to alter the bolt pattern. However, with the deep backspace of the 4th Gen F-body wheels, its almost impossible to find a Mustang wheel that would fit inside the fender with the addition of the adapters to the already real wide hub locations.

 

what is the offset for rims on a 4th gen?

 

Stock 4th Gen wheels are:

Z28/TA - 16x8 55mm offset, approx 6-5/8" backspace

SS/WS6 - 17x9 55mm offset, approx 7-1/8" backspace
