Would it increase the gap at all? I know a lot of people have wider tires in the rear for performance reasons, but is it uncommon to go same tire specs all around? The main reason I went with a squared setup was so that I can do tire rotations to extend the life of my tires. If so, what are good tires specs for my setup? This is going to be my DD that will be driven spiritedly, but rarely tracked. 

The other reason I went with the 8.5 over the 9.5 is because I wasn't a fan of the concave look. This is pretty much how I want my car to end up looking.

Wheel Offset

Refers to how your car’s or truck’s wheels and tires are mounted and sit in the wheel wells.

– Zero wheel offset is when the hub mounting surface is in line with the centerline of the wheel.
– Positive wheel offset is when the hub mounting surface is in front (more toward the street side) of the centerline of the wheel. Most wheels on front-wheel drive cars and newer rear-drive vehicles have positive offset.
– Negative offset is when the hub mounting surface is behind the wheel centerline. “Deep dish” wheels are typically a negative offset.
