How far have you thought this out. In my minds eye I see all kinds of strange hook ups. Probably a hundred ways to do it, but I'm not sure it's worth it for a car. I could see it working on twin I-beams say on a Ford truck but the back seems difficult. Some geeky engineer could probably pull it off. My '68 Chevelle had rear coils. I kinda liked them. Try it, it might make you wealthy.
