Sub-frame connectors... Please build them correctly!

I have to say.... All the input here has been valid. None of it....none... has fallen on deaf ears with me.
According to my stress analysis the attachment to the floor has a difference of around 30% in favor of welding to the floor pans. Now of course there are many more factors that would require me to reverse engineer the entire uni body structure in order to prove the point with out a doubt, but you all get 're point based on the items shown.
I cant rightly show a decent result of the stress in stock form because of the amount of reverse engineering involved.
Anyhow... all that said... IF...........you do a few key things .....namely spread out the force from your tubing to the sub frames by making as much contact as possible you will greatly increase the strength of even the floating style connector.

Im glad that you all step up to throw in your two cents as this is also the way I do things daily at work. I like to hear input from everyone, no matte let who they are and what position they hold because you never know who is thinking od something you are not!
thanks guys...
Bottom line... as the stress analysis shows... Its better to attach it to the floor. ;)
