Anybody running 17" Cobra Bullit rims on a Duster

I think you're on the right track - the same way you're calculating the fit of the larger BS on the wider axle, you can also use the "front space" plus the axle width to see how the whole assembly will fit inside the wheel wells. You can gain an easy 1/2" per side by massaging the inner quarter panel a bit near the top of the tire.

If you aren't committed to 17's, you can probably solve some of the interference issues (UBJ zerk and OTRE) by going with 18's instead. I don't think there's a big weight penalty, and the 18" tire selection is great.

JR... Thanks man! Ill be checking it out!

Thanks everyone for the specs! Awesome info to have when I am about to change this much back there!
Well I did a little looking and found that the 8.8 width (mounting surfaces) are 59.5" wide.

According to a few charts... the A-body 8-3/4 is 55.56" (That doesnt seem right) I thought it was 57.5" for the a body 8-3/4

Anyhow... This helps with the wheels I am considering.

Wheel specs are as follows

FR500 style
SIZE: 17x10.5 OFFSET: +27 millimeters BACKSPACE: 6.82 inch

If the numbers are correct for the A-body specs, and it seems to be the consensus that about a 4.75 backspace (for the rear of car) is best...

Then the added width of 2" inches to each side sets me right back in the same ball park with only about 1/8" to figure out where it is...

4.75 Ideal BS (w/ 8-3/4)
+ 2" that Ill gain at each side with the 8.8 swap
= 6.75
BS on these wheels being 6.82... Im not far off at all!

This doesnt however address the outer edge of the wheel and possible contact with the fender well edge.

Does this make any sense? Hahaha...
