riding heights for w123

[abotakwa]

hi
i have a prblem in my europian car w123 model 200 year 1979 . it is unstable especially if there is wind . i changed the 4 tyres and the 4 shock absorbers and every thing need to be replaced . i made wheel aligment 5 times but still the same .
so i like to know the part number or the width of the front and rear shims of the springs for my model with the following options(sunroof and power steering).
also i like to know the riding heights for my car . is there a difference between (the distance between the tyre and the arch)for left and right at the rear . for my car there is 2.5cm difference is it normal .
