Anybody running 17" Cobra Bullit rims on a Duster

So............ lemme' drag this to the top for the pro's to answer.

I am looking at a pair of "ZR500" wheels.

Info I have been given: Stamped on wheel is this 46 17 05 210

I have gone to a site that sells these and the number doesnt match up to any of the offered wheels.

The 46 seems to be the "style" of wheel.
The 17 is obviously the wheel dia.
Beyond that.... I got nothin!

What I can see from the site is that in a 17" wheel they offer only 2 wheels.
Since I have a picture and the wheels I may buy have a "lip" I can only assume it is the wider of the two offered.

Specs at that point are as follows.

Product ID : 46171652
SIZE: 17x10.5 OFFSET: +27 millimeters BACKSPACE: 6.82 inch...

The backspace is pretty deep.

So the question is.............. Will they fit with a spring relocation kit and a spacer?

Lots of tried and tested experience here so I am hoping the answer might be here.
Thanks guys!
