thx Anassa, most important is that we can share and understand between us.
E36 compact is very sensitive to the weight load in front of front axle... I guess there should be like a "balance" of weight which are over axle.
E36 are known to be "sluggish" with front axle, and need X-brace to get a more reactive steering. I have this X-brace to fit to improve my chassis again.
after that I'll study some roll center correction :
