Please measure from the frame as suggested.
for alignment purposes and scaling the car. I put my weight of bags of salt in the drivers seat.
I break a paint stick into 2 small pieces. Go to one side press up against the frame and floor. Take the same measurement to the same spot on the other side and adjust as needed. Summit sell a little spring deal to accomplish the same procedure.
their are exact spots front and rear ro do the measuring and exact heights. I can not remember the mm difference between front and back but..........I would not change that rake percentage.
I bet someone here has one of the old Manuel's and can provide the proper info. I will look and c if I can find it. If so I will post.

Adjusted the rears up some more, I'm now right at 5" to the frame rail in front and right at 5.25-5.5" at the rear. The ride is better, but still has some bounce, but nothing near as bad as it was before. I cleaned the dirt off the shocks and will see if it comes back, it was only on the front of each rear shock, so I'm guessing it was just road dirt/grime. I may just have to do stiffer rear springs as I really don't want to go any higher. Of course I could just pull the whole setup and replace with VanSteel's DA4 max lowering setup.
