Caster is the same for both front and rear
Toe is the same for both front and rear
I knew someone would reply and say caster is adjustable. Wasn't clear that anyone has FRONT SPC arms, and since caster is the same for both cars, you will have to max out the adjustment nut to get the caster as close to stock numbers as possible.
The only difference, based on the charts between the two cars, would be camber. Like I said you can put this wherever you want.
G35: -.83 - +.67 front
350Z: -1.33 - +.17 front
No difference, it should be around -.75 anyway.
G35: -.17 - -1.17 rear
350Z: -1.08 - -2.08 rear
I've always put my sedan rear at -1.5 and do not have any more tire wear than normal.
And if your interested in adjusting to nominal numbers, your car might handle a little better with the 350Z numbers. Not a terrible idea to choose either car for your alignment.
Would you say all 350Zs with proper alignment numbers wear their tires faster than all G35? Nobody will notice a difference between .75 degree of negative camber.

The 350Z has slightly more camber for a reason: To improve handling during cornering. Technically, this should also result in slightly more tire wear as well. I don't think the difference between the two alignments is that great either way. I've ran 350Z alignment for a year now because I wanted better handling. My tires have held up fine.

The OP clearly says that he has SPC Camber arms. But in general/stock, no it's not adjustable, neither is camber in the front.
And yeah only real difference worth talking about is camber.
The front should be at ~0~ Camber ideally, or just a slight bit of negative.
More than -0.50 camber in the front is excessive.
IMO 1* of camber difference is a signifigant difference when alligning.
But running -1.5* in the REAR on a G35 isn't going to roast tires off, they just won't wear AS evenly as they WOULD with, say, -0.50* in the rear.
I would allign ~0~ front and -1.0 rear as a goal for camber.
If he doesn't have toe bolts and/or camber arms setup in the rear though it's pointless to talk about because he'll be stuck running 350Z specs in the rear anyways (more negative camber). The front just set up for 0* camber and a .01 toe in.
And yes 350Z's are known for camber wear on the rear tires especially.

Most places won't adjust the front arms without charging more. And you really need to explain it to them.
I did mine by eye then took it in for the toe adjustment. They didn't even touch the camber, it was almost bang on 0.02//-0.02 left//right.
I was shocked at how close it was, probably sheer luck lol. They did adjust the rear but they needed more toe adjustment to get camber in spec. Unfortunately I forgot to notch out the slot for the new toe bolts!!! DO'H!!!
So I'm running -2.0//-2.5 camber in the rear until I can get the toe bolt slots done.

if you're ok with using 350Z specs you can use the stock cammed bolts for camber/toe adjustment. If they're not seized.
#24
SPC front camber arms with Camber Plates installed
Rear Camber arms
Rear toe bolts
That is the only hope you will have to get to spec. The biggest investment is the front Camber kit.
Running proper camber when slammed requires fairly precise fitment and/or non-agressive offsets though. most guys just opt for silly negative camber so they can drop the car more. It's easier, but costs more in the long run.
