Some of this leads to some strange interpretations/results.

Integrated bumper cars have a whole lot more options in attaching the splitter/air dam. And it all turns on whether the bumper has a plastic or rubber cover on it. Old Z cars with metal bumpers have to have the spoler attached to the body. I (and 2nd Gen RX7s) get a larger airdam that protrudes out futher and is able to attach to the "integrated bumper assembly."
