Wow, sorry to see the loss, but definitely happy you are ok. Anything you can do to tie in suspension and chassis will help and these cars being unibody are no exception. I was looking at a cage as well as frame setup to make the car as rigid as possible. Very scary to think that the mod you did is what possibly saved your life and you could not be here posting this. Again, glad to see you are ok, a car can always be replaced.
