Backspace is the distance from the inside rim edge to the hub mounting surface.
Offset is the distance of the hub mounting surface from it's centerline. Zero offset means the hub mounting surface is at it's centerline. Positive offset will narrow the track width. Negative will widen the track width, also sometimes chosen to help tires clear suspension components.
