A front 9"+47 offset will sink way in on the rear & probably hit the brakes? My factory base 9"wide rears are +15 with a 5mm spacer/ but I have less that 1* neg camber.....tires will evenly wear on your Z unless you are burning them off,,,negative camber is for the curvy roads.
I mostly straight line & burn mine/so I adjusted my camber more straight up & down. You would need 35-45mm worth of spacers to bring a front wheel flush on the rear of a sport...not recommended. The rear 10" on the front will be 5mm further out than the stock wheel w/25mm spacers.
