I strongly suggest using a pyrometer to determine the camber needed for the 350Z. Just because folks in other cars run camber numbers of -3 or more doesn't mean its right for the 350Z. The front of the 350Z gains about 1.5 degrees of negative camber in bump with 2" of bump travel. There is also some negative camber gain in bump from the 9+ degrees of caster (about .5 degrees). Combining the suspension and caster camber gain my guess is the car has about 65% camber recovery in roll which means it requires less static negative camber to start with. Some of my testing with a pyrometer confirms this.

But, a lot has to do with tire selection so that's why its important to test on your own car and setup.
