I am really surprised this didn't kick up

This guy is only partly right- he needs to go to engineering school. I have been involved with motocross since the '60's. Those who really want to understand chassis stresses and flex and their effect on suspension and handling need to get educated. Beware this guys advise.

Exactly.
There's a few vids that have been shared that have a very odd take on it's subjects intended function. With very little understanding...people eat it up... like yeah it makes perfect sense they want the whole car to flex, twist and move around...because shocks,bushings,tires dont already do that right...
New cars, the cheaper line... all unibody...full size, the expensive line, some full frame.. bushings better known as insulators dampen the road noise...and not to help the car move around. The more you spend the quieter it gets.... more cashola more rubber between you and the road. While some flex is engineered... I cant agree with the video , the way its stated and relating it to frame connectors anyways.
