You can go LS to Taurus, but with a 60mm offset, you'd need one helluva spacer so that it wouldn't rub the struts. I had Gen III steel wheels with snow tires on the LS when I drove that year-round. Still needed a spacer with the SHO wheels so that they'd clear the caliper on the front.
If I get a few minutes I'll see how bad the fitment is on my cars; although my LS has 17" wheels, but the offset is the same.
