Need negative offset for widebody kit?

[ProjectDemon]

So I’m looking at putting some fender flares on my 2010 gt, and I want my wheels/rims to be flush to the flares (obviously). Any suggestions for rims? I can’t seem to find any that provide a decent enough offset to make sure they sit flush. The kit is 75 mm (3”) flares and right now my wheels are pretty much flush to my stock fenders, so I’d need to gain atleast 3” of offset. Any suggestions help!
