Frustrating night working on my rear suspension. First, it appears that the left rear spring perch got cross-threaded or I have to remove the spring pressure from it to try to get it to move (it moves an 1/8th of a turn and that's about it).
So after I turned the shock in about 1", I had a much better ride, not hitting the bumpstops nearly as much, but it felt like it still bottomed out going over speedbumps and still oversteered some. I measured the droop at about 1 1/4" in the rear, which is lower than spec (though no online spec... only someone's online notes). Decided to turn in the shock another 5 revolutions, giving up just under 1/2" of droop. So now I have about 3/4" of droop, which maybe way low? Haven't put the car down yet and test driven.
Another thought is that having the rear end raised up higher than the front is also causing some oversteer (rear center of gravity is different). I'd lower the rear end a little bit, but now I am messing with the alignment (and I can't get that damn spring perch moving).
