Here is my '97 GS with H&R Sport Springs, KYB AGX Shocks and the front camber kit installed. The back is definitely higher by about 1/4" but then again it's supposed to be. It definitely has settled down a bit in the back over he past year.
As for the tires wearing, I had it lowered without the camber kit and it was pretty off, enough to where I pulled it all apart and put the camber kit in, since then the tires are fine with no signs of wear at all.
