No. Factory wheels have different offsets and width front to rear.
Fronts are close to 4.5/1.5
Rears are close to 5/2.5

No.
The reason putting these on the front would increase the track width is because they are slightly more offset, not due to rim width. They are about the same total width as the stock fronts at 6.5".
