post car question
I have been deep in restoring a unibody mopar, thinking about strength and rigidity (how the K frame is part of the overall equation) and the thought came to me, why did GM do a post car body on a full frame? I don't understand why it is so relevant that the shell be made stronger on a full frame vehicle. Does a GM full frame really twist that much with it's cross bracing?
There are unibody cars that can lift a hemi off the ground pulling a wheel stand, so what am I missing on the 'post' angle?
I can see how a post on a roadrunner makes sense (still an unibody, they made a few that way), but on a full frame car, I am not getting it that it makes that much of a difference.
Now if the car flipped over, I would rather be in a post car, no doubt on that [img]<<GRAEMLIN_URL>>/smile.gif[/img]
Had to ask. I think there are some 'post' guys floating around here....
