the stock camber on a sunny is 0 degrees, and with a good setup that is pretty responsive, you'd not want to run any more than -2 on the street, adding negative makes steering really darty and wears tires out quick.

I say -2 in part because some FWD cars run a little - camber already. If where you live messing with the camber is illegal, then don't do that.

i have camber plates so I could experiment with more -camber, but so far it's just fine at 0.

if you're swapping bits, you could also use 280zx struts and hubs,brakes with sunny LCA's and get way better brakes.use your old strut tops and change to shorter 240sx springs ( i think this is the cheap way of getting the more expensive swap I did. )

Make sure to do your research, but my swap went off fairly smoothly and is very reliable.
