Except for the backspacing which I can't confirm, those look like they'll fit. Just check to make sure the center bore is at least 106mm. Note that the OEM wheels have a 10mm offset, so the Six Shooters will protrude outwards 10mm more, and the Countersteers 10mm more than that. That usually isn't an issue and probably desirable, looking at the type of wheels you have in mind
For reference, the specs on the OEM wheels, found on
http://www.wheel-size.com/:
Diameter: 16"
Width: 8"
Bolt pattern (PCD): 6x139.7mm
Offset: 10mm
Center bore: 106mm
I'm assuming you'll be buying some new tires too, so it couldn't hurt to give the folks you'll be buying the tires and/or wheels from a holler and see what they say.
Those look really sharp! Take some pictures if you end up installing them. I might be interested in a similar style myself.
