The absolute largests (for the rear) would be 11" wide, with around a 50 mm offset. That is the Corvette ZR-1 five spoke. Now there is a version with 36 mm offset, but that sticks out of the wheel well and will dictate fender lip mods. The 50 mm will require inner fender mods (the 5lb sledge mod) Use 315/30ZR17 tires.

Now, you are lowered quite a bit, so in my honest opinion stay away from the 11" wheel. 10" or 10.5" would be the widest I'd go. And again the offest would work out great at around 50 mm. Use a 295 series tire.

I have 18" x 10.5" Z06 wheels with 295/35ZR18 tires. Still had rubbing issues on the inner wheel well, nothing a hammer couldn't fix. The wheels were 56 or 57 mm offset, but I'm now playing with a 5/16" spacer with is 7 mm so I am trying to get the offset to 50 mm.

Hope that is the kinda info you are looking for.

I have a quick ? your info I think is weird. If the offset is 50 from center of wheel then a 56 from center of wheel would push the mount to the outside more and the wheel in toward the inner wheel well??? right?? larger offset sucks wheel in I believe???

The 50mm 'Grand Sport' offset is the one that works best for the F-body. This is what I have on my car and it makes the wheels pretty much flush to the wheelwell opening.
