No. The ones fitted have a 50mm offset so they foul the suspension without spacers.
My rough calculations give me the following:-
5.5J standard wheel with 39mm offset gives me 109mm from inner face to rim edge
6J replacement with 50mm offset gives me 126 from inner face to rim edge, the 15mm spacer takes this down to 111 mm
On standard wheels the permitted offest range is 37-42mm, so I reckon no more that 3mm off each spacer should bring it back in to spec, but can't see how 6mm across the axle could make such a difference........
