What is the offset or backspacing of your wheels--and how wide are they?

Impala SS wheels fit wagons with no problems, so any aftermarket wheel with similar offset (+6mm) or a high(er) (positive) offset WILL fit.

The only issue with an adapter is that it MUST be a minimum of 0.750" to 1" thick (depending on the vehicle), to "cover" the existing wheel studs and lug nuts, which cannot normally extend beyond the outboard face of the adapter. Plus, an adapter has to have sufficient strength to hold wheel studs, so it cannot be too thin--again, the minimum thickness is going to be 3/4" to 1".

Anything less than 3/4" of distance to fill between hub and wheel, you're looking at some sort of spacer deal, rather than an adapter.
