Default max. positive offset 84 Corvette.

I am looking for a wheel with the max. positive offset for an 84 Corvette rear axle assembly for my project.
I would like to run a 15" wheel with an aspect ratio of 50 to 65 if possible on a 6.6" width wheel.
My goal is to have a small diameter tire in order to fit somewhat in my fender area and to keep the car with a low stance.
Traction is not a consideration.
The axle assembly is installed in an 84 Ferio.
The wheel would probably come off of a front-wheel-drive car with the same bolt pattern as the Corvette.
Could someone help me out with such a wheel?
Thank you, Roger

I'm sorry, but nobody here is going to know anything about 6.6" wheels. Nobody has ever put such a thing on a C4 Corvette! You're fitting this in a Fiero, which means you are running your own experiment. But just looking at your pics, I see that the hub face appears to stick out beyond the fender edge, which means you need a wheel with more backspacing than width! For a 6.6" width, that means you're looking at offsets in the range of 74mm or more. I seriously such a wheel exists off the shelf or as OE equipment on any car. You'd need to be looking for custom wheels, if anyone is even willing to make such a thing.

They really don't stick out as far as it looks, I had previously narrowed the body 9 " and I had fender extensions to cover the original wheels.
I will be using fender extensions on the finished project.
I will be looking into custom wheels from the Vintique wheels when I complete the alterations.
Thanks for the reply.
