GM and Ford both have some great engineers but they also have ACCOUNTANTS, which have ALL of the power when it comes to design. It is not that the engineers don't know what is best, it is just that in most cases, they have to compromise their designs to produce a "suitable/servicable" vehicle at a lower cost. Aftermarket improvements are available for the owners that can afford to improve on the items where the engineers had to compromise.
