Alignment results... what's wrong here?
 

I noticed that all tires on my car show wear along the outer edges on both, the inner and outer sides. I took the car in to get aligned and here is the printout...

The tech said he could not adjust the rear camber any further. I'm thinking this probably has something to do with 150 lbs of audio equipment in the trunk.
Is it worth buying a camber kit for the rear to bring the camber into spec?
I was mainly concerned with toe being off, but it looks like that has been addressed. Just for the record, I run 33 psi in the rear and 35 psi up front for tire pressue.
Any input is appreciated.

No, I wouldn't think so. Lots of folks actually request a bit of negative camber for the added performance benefit; still others, just to compensate for poor tire/wheel fitment. You are so close to stock range it's not even worth worrying about. You did mention a valid point though about having weight in the trunk making a difference. If you really wanted to get accurate, you could have also weighted the front seat with your equivalent weight as well. Then the car would be set to it's most normal weighting (assuming you typically drive solo more often than not). That toe was definitely off enough to scrub your tires before though.

Agreed. I actually had one of my other cars dialed in with me in the driver seat once.
In this case though, I wanted the rear camber set to -0.25 so that the front (@ -1.0) and rear camber settings would be further apart relative to each other for more oversteer bias. The way it ended up is that I have more negative camber in the rear than front, which is the opposite of what I was after. I took the car through a nice curvy road that has a gradual turn with a recommended speed of 35 mph. Posted speed limit was obviously much higher than that. So I took the turn back and forth until I reached the limit of traction and sure enough, the front end gave out first. The car felt very predictable, but having driven Subarus prior to the G, the one thing I couldn't stand was horrible understeer those cars suffered from. By the way, the car reached its limit of traction fairly close to the posted speed limit, which is still 20 mph higher than what the recommended speed was for the turn.
