Observations on rear camber and its effects on tire wear...
In early April (about 4K miles ago) I had Bilstein & Eibach combo installed. The springs lowered the car by a little more than an inch. I did not do any camber adjustments on the rear wheels, and the camber came out to be -2.0 (driver's side) and -2.1 on the pass side. I think -1.5 is the factory spec.
Since the installation I have put on about 4K miles, including 2 track days. I rotated the tires right after the 2 track days, and now have about 3500 miles on the current tire rotation.
I have Kumho Ecsta 712s, and they have tire rotation indicators (little holes at increasing depths). The rear tires have almost worn thru to the 2nd rotation indicator on the inside of the tire, but on the outside wall, the 1st rotation indicator is still visible. (When the indicators disappear, it is time to rotate the tires.)
The effects of the negative camber is more pronounced than I had expected for a car that is lowered by only an inch or so.
My Kmacs are going to go on very soon.

Sang.. here's some more numbers for ya...
While -1.5 is the high end of the factory spec's, the range goes from -1.5 to -1.1. Your -2.x seems a bit more drastic than I would have imagined for that amount of drop.
When I put on my Bilstein Sports and AbT springs, my camber was -1.32 (L) and -1.16 (R). I am hoping that my wear is not as significant as yours, and the numbers seem to lean in that direction.
Anyway, good luck finding a KMAC kit. Seems that they have been hard to get recently.

Glen...Thanks for the additional Info....
Fortunately, I've already got half of a kit. When I get the car aligned, I'm going to ask for them to set it at around -1.4 to -1.5. I do like the aggresive look of the camber, but it is too much at this point.
