What I need to know is what do I need to do to the suspension to get this rig to handle rock solid ?
It may never be "rock solid".
It has about as much side wind resistance as the side of a barn.
And there is NO steering "feedback" and no good sense of slow deviation from a good line......so constant attention is required.
No doubt that you can improve things some but I think you will soon notice that big vehicles overtaking from the REAR will tend to push the BACK off line......and that is not due to a fault in the suspension.
