Wheel Offset Discussion Thread... How far can we go?

[Da370z]

Any feedback would be appreciated, looking to buy a wheel and tire package for the z next year, trying to get a nice flush look maybe very slightly aggressive, im looking at 19x9.5 +22 for the front and 19x10.5 +22 for the rear, im running a 20mm spacer in the rear to sit flush now so im assuming that will make it +2 in the rear which i think would be flush? im not sure. im running 18x8 +20 for the front and 18x9 +15 on the rear right now with the 20mm spacer, im also on eibach springs so im dropped about an inch, thanks in advance for any input
