Yep, I'v tried it, you just use the entire front and rear cradle (struts, hub assembly, rotors, calipers, axle etc) and it bolts strait up. You don't need to use the control arms as the u12 ones are the same - onley the inner section that the sway bar bolts up to is different on the Maxima, so you can just change it over or just keep your existing u12 swaybar, but from memory - the rear assembly will need to be changed.
I am using S13 struts with GTR breaks n rotors in my u12, its a lot of customization and a lot of money. J30 Maxima parts will save you the time and money.
