The stitch weld solves the problem , but , transfers those forces back into the chassis and wish bone bushes.
So it dosnt pay to go to hard with springs and shocks as something got to absorb the applied forces.
I've seen shock absorbers used from inner mud guard to engine block to help control engine movement , but didn't use that myself.
