Default Rear Toe, camber, and tire wear

I'm lowered on Tein s-techs (about 2" drop), and just got an alignment about 4 months ago. I just threw a set of used tires on for the time being. The tech had no problem aligning the front, and got everything in spec. However, the rear camber adjustment was maxed out at negative 2.5 degrees.

In only a few thousand miles the inner part of the rear tires is already almost out of tread (starting with about 5/32 of tread). From reading on here it sounds like -2.5 degrees camber isn't even that aggressive and most likely the toe adjustment is ruining the tires? I don't remember the rear toe setting, and unfortunately their printer was out of paper. However looking at the car the rear seems to have a noticeable toe-in, along with the negative camber.

I don't want to pay for a rear camber kit install if adjusting the toe can still give plenty of tire life. Any ideas or advice is appreciated. Thanks!

I should also mention recently the rear has felt a little "darty" over dips and sewer covers on the road.

im an alignment tech. sounds like your toe is off, try increasing tire pressure to get the middle to make more contact patch

Toe is what is killing your tires.

And why did they only adjust the fronts?

They did adjust the rear, but camber was maxed out at -2.5. I don't remember what he set toe to.

Any recommendations on on a good setting for rear toe?

I will double check tire pressure as well, thanks.

How are your bushings and ball joints in the rear. I previously had problems with wear on my rear tires as well to find out that I had major play in all my ball joints in the rear.

I'll have to check I haven't heard any clunking or anything from the rear. What did you end up replacing?

In my experience, by the time it starts clunking that means it is completely busted. Our cars are old, so a lot of parts are worn even if they don't make noise or look damaged.
