My second option is assuming that:
1 weight is transfered to the front
2 chassis in the rear travels up
3 and rear arms go down
4 now the downstops kick in
normally this is the point weight transfer stops to the front.
But ...
if downstop value is to high / droop too low and springs in front are rather soft following can happen.
6 downstops kick in
7 you turn more in
8 chassis rolls to the outside of the corner and weight transfer to front goes on.
9 and because the rear inner wheel trafel is totally blocked it lifts.
10 side grip gone
11 spin or at least oversteer
Hope this helps.
btw: why not go 1 step stiffer in front instead of yellow in the back as a test?
