Gee. I'll play. (nice control arms ya got there)My car came with QA1 single adjustable coilover front shocks but the front end seemed high, they banged a lot on bumpy roads and I could hardly push the front down at all, even with the damping on full soft. Anyway I adjusted the ride height to the bottom setting but it's even worse now. Measurement is 26" from floor to wheel arch. I'm thinking that maybe the springs are wrong, or possibly shocks are too short but I haven't dropped one off yet.

What's the wire diameter on the spring/do you know the rate?
Usually single adjustable shocks only vary the rebound via the adjustment. And if the single knob does
vary both bump and rebound, it's almost guaranteed to not be the correct ratio. Roughness in bump on the front
end is softened through spring rate and the ability to correctly adjust bump & rebound in the shock.
Just a few things that come to mind.
