Looks like it is the weight that affects the amount the car is lowered...also the same reason Racing Beat only offers their springs for the hatch. This is a reply from Jim Langer at Racing Beat.
"While the suspensions are the same, the weight of the two models are
different. Using the same spring for both applications may cause a
ride-height concern. (In fact, Mazda offers MANY different stock springs for
this application depending on whether the car is equipped with AT trans,
sunroof, etc....) This only makes it more difficult for us in the
aftermarket to design "one" replacement spring for each application.
What we really need to do is get our hands on a sedan (we have a 5-door) and
undertake some testing.
i don't know what that tells you, but to me it says "case closed".
bottom line: if you have a sedan, springs aren't going to be as low. yes, both suspensions are fundamentally the same.
