You raise a valid point, and I have asked myself the same thing. Perhaps it was partially due to the fact the tech seemed to be lacking in skills or equipment to deal with a lowered car. In hindsight yes, I agree, I screwed myself over in this case.

Anyway, the tires appear to be wearing uniformly. It was previously chewing through the rears in 15000 miles on 40000 mile rated tires.

I'm curious whats causing the pull of the right though. What could cause this? What parts should I really investigate? Perhaps spring pads or control arms?
It appears to have an uneven stance in the front (FR is lower that FL by half an inch). This appears to throw off the camber, so that it is positive on that wheel.
