Platinum 850

So I have an opportunity to pick up a set of rims, I have identified them as Spartacus...

They are 17".

Has anyone run these on a 850?

The only specs I could find were:

Size:
17" x 7"

Style:
14 Spoke

Lugs:
5

Bolt Pattern:
108mm

Offset:
52.5mm

Notes:
Volvo calls this wheel "Spartacus"

Sourced from this website: http://www.allfactor...17"-70317-.html

Here's a physical pic, of the ones I'm looking at, have I identified them correctly, and does anyone know if they are the same size bore as 850?
And with a 52.5mm offset, I severly doubt that they will clear my Porsch Calipers, I do have 15mm & 20mm spacers... the other thing that concerns me is the rims phsical ID (i don't know what else to call it), but I don't think that there would be enough clearance with these rims to clear 13" rotors and the caliper...

So anyone that might have some input would be greatly appreciated...
