It appears than the specs are at 45mm offset and 9.5 wide.
That will give you ~+7" backspace. It's well known that the max you can install in the front is 6.42" or so. SO, they won't fit in the front without at least a 1/2" spacer (BAD IDEA) or narrowing them 1" or so (doable but $200 or so a wheel). The front space is exactly where it needs to be for both front and rear flush look at 3.5". So it's all about the cost in the end. Definitely not a bolt on and go deal. Local Weldcraft does a great job on narrowing or widening wheels, but it's only a reasonable choice if you're dead set on the specific wheel. They do look good though.
