Oh, and flex is one of those things that is not necessarily better or worse. It is a matter of where it is isolated. You don't want excessive flex around bulkheads like before. Now our bulkheads are not as "stiff" as the older designs, therefore we have changed chassis design to compliment this. If you incorporate flex around the newer flexible bulkhead designs you end up with cars that cannot put the power down properly and that has trouble tracking straight.
