The problem with the f18 gear is the extreme course it has
In order to have this extreme course and compression I was obliged to define a very low stiffness in a wide range of the compression and then increase stiffness a lot in the second range
This creates unexpected behavior like extreme rolling when turn , wobbling ….
If you increase the stiffness « 1 » and increase defzone1 to 0.8 it should stop
Problem is that the model will not sit like the real then
You can also try to increase amortization in detent vs compression
