Excessive Tire Wear

I just had the Sumitomo HTR ZIII 295/30/18 tires installed. I drove it for a couple miles and the tires felt fine. I had an alignment done. I made the mistake of not specifying the alignment settings and they set it to stock. It is now scary to drive. The rear end feels squirrely. My before settings on the back were -2.2 and -2.4 degrees of camber. I ate through a set of back tires in less than 5,000 miles. The rear is now set at -1.2 degrees of camber on each side. Toe was within stock perameters.
My fronts are at -.8 and -.5 degrees. I am taking it back tomorrow to have the camber settings changed...Any suggestions for how much negative camber to run front and rear? (lots of spirited driving on country roads and hopefully a couple track days)

With the Sumis, you will get better wear.

I eat rears before 5k miles, too. A lowered suspension will do that (OP, you have PSS9's, right?), and a widebody will further exacerbate that, apparently. I've resorted to running the Sumis, so at least I don't cringe as much when it's time to replace them.

TD and ED, thanks for the advice guys. I would rather go through tires every 5,000 miles than have it handle like it does now. 1.7 on the back sounds about right. The Sumis are defintely less painful.
Pete, I voted for the other guy.
