If you drive straight 100% of the time on flat roads, zero camber is perfect. The more you turn, the harder you turn, or the more lean the car has, the more negative camber you want in a Z. I am running -1.3 up front. I get it by lowering the car 1" from stock with tokico springs, illuminas, bump-steer spacers, and by using the eccentric bushings from MSA fully extended. After a moderatley fast drive on twisty country roads, the tires are eveny heated across the thread. That means they are probably wearing evenly. Before I added the front negative camber, with stock alignment, I used to wear out the outside front edges all the time. In the rear I now run stock alignment resulting from a 1" drop, but plan to add -0.5 to -1 degree and maybe some very minor toe in if possible, for braking stability.
I run relatively massive sway bars... 1-1/8" and 7/8". I had to loosen the front endlinks to get the front to bite better on corner entry and mid corner. Also, use rubber T/C rod bushings on the backside of the T/C bracket and Poly on the front side.
