I went home last evening and looked at my pictures taken of my ACE in the trailer when I purchased it, (pre strapped down), and I can't really tell from that how the rear camber was originally due to the lens distortion of cameras and the perspective. I seem to remember that the rear was a little bit positive with the shocks at the lowest setting, which isn't really a bad thing. As was explained to me, anywhere between 0-2 degrees positive camber should not cause any improper operation or problems.I've never had mine measured, but to me my rear camber looks positive. I'm not sure if it zero's itself out when I sit in it though or not. I thought that was kind of weird.
