So, I have been reading around and can't seem to find a sure answer on what to do exactly. I have recently replaced my tires, installed myself.

The first time I aligned my new tires, the fronts had stayed in factory spec, and so had the right rear, but the left rear had a toe of 0.20 which I had returned to 0.09.

The second time, however, was much worse. The right front had a -1.4 camber, and was only able to be returned to -1.3. The right rear had a toe of 0.15, which was returned to 0.11. The worst was the left rear, which had a toe of -0.20, which was returned all the way back to 0.11.

This is a picture of the first report: https://i.imgur.com/YMRFs.jpg
And the second: https://i.imgur.com/5DsKd.jpg

I am looking for a permanent fix for the tire wear/feathering... and I am not sure why my alignment is going out of control so fast, seeing as the two alignments were only a week or so apart. I would like to fix both of these issues. I have seen people adding a camber kit, and others adding a controlling arm... If any of you have fixed this on your 2003, please let me know what you did, and what brand parts you bought! Also, if anyone knows any shops around the Sacramento, CA area that know Z's well, that would help as well!

Thanks for the help in advance!

 

Well, there's that sticky thread that has a ludicrous number of pages and is impossible to find any discernable facts, but aside from that, I wish I had an answer.

 

Yeah, there are just tons of replies on that thread, and everyone who's fixed the problem all seem to have different solutions... Right now I'm looking into probably getting SPC arms for both the front and rear and getting those installed.
