I realized that in the hull there are two holes for each arm, and the spring were placed in the easy one, just to make the build faster. I reclocked to the second one and the suspension improved a lot.
The springs the models provide are stronger than the regular one so I think is just a problem of setup. I will make an extra hole and try from there, if doesn’t work then will go for the Asiatam ones as you suggested.
Thanks my friend I appreciate the help and comments.
