does a 15x7 weld draglite with a 3.5 backspacing fit the z?

It will fit, but you will be better off with 4" backspacing. I had 14x7 Autodrags on my car with 3 5/16" backspacing. They rubbed on the drivers side, but that is partially because of a previous repair to the lip. Th 16x7 I have now are 4" bs.

So whats the max backspace you can use with 15" wheels and STOCK struts in the front and rear?

A lot depends on the diameter of the wheel and the OD of the wheel tire combo. With 15's I would guess 4", with 16's 4 1/2" and same with 17's. You can modify the rear perch and uses shortened 2+2 springs and get a 245 50 16 on the rear with 5" bs. Your best bet is to test fit a wheel and tire combo and make measurements from there. Not all cars are the same (witness my problem with drivers side rear.)Join a Z car club locally or just try and find a member here near you who will loan you a couple of hours and a wheel/tire to test fit. If you would fill out a profile, people would know what part of the country you are in. You should also post what year your car is also since in some cases that can make a difference.

Hey JasonK if you weren't such a dumb ass you would know that answer.

The suggested back space is 1/2 rim width + .5"
