In the case of a straight axle "Street COPO" , there would be added cost of research and engineering because the COPO is intended for track use only. On the street, the suspension would have to be tailored to now having a straight axle that can still ride decently on the street and perform at the drag strip. Also, most importantly, it would have to be safety/ crash tested/certified. Any changes you make to the cars, especially a major drivetrain assembly change, has to get re-tested and certified, thus more R&D money and testing money. Even removing the components like radios, back seat etc requires re-testing....
