I am really surprised this didn't kick up

Is that kind of stiffening a benefit on overpowered street driven cars that just break the tires loose, unlike a purpose built drag car with slicks that hooks on launch and stresses everything to the 9's?
As for handling, I've seen cars just add stiff t bars, springs and shocks driven on 21570's that will understeer right off the road when pushed if your not careful.Drastically increasing the chassis stiffness on these cars requires some thought and maybe further modifications to keep it safe.
