Quick Question: Subframe connectors- WHY didn't they do this from the factory?

It couldn't possibly have cost much money to extend the unibody reinforcement a couple feet. Is there a reason that they opted not to? It seems insane.

Is there anyone out there (other than those restoring a car to factory specs) who thinks that welding in subframe connectors is a bad idea?

couldn't of been too bad of an issue; everyone at that point except chrysler were making full frame cars, now everyone is making unibody without any frame connectors

seems everyone followed chrysler because as "crappy" of a design people think it is; its more rigid, holds up better in a crash and the occupants have better chances
