regarding wheel offset;

negative offset sets the wheel farther out. the backspace is reduced because the mounting surface is closer to the inside of the rim. this allows a wider tire or a wider stance.

positive offset sets the wheel closer. the backspace is increased because the mounting surface is closer to the outside of the rim. this allows a tire to be "tucked in" into the wheelwell. of course, you need the room around suspension parts for clearance.

zero offset means the mounting surface is in the same line as the centreline of the wheel.

bolt pattern is one thing, but there are many other aspects to consider

 

I was being facetious.
there is no "right" in this case...we're doing something different, custom, non-factory. stock specs don't pertain here really.
