What's up with bouncy suspension?

Okay, here goes stupid question.

What's up with some subarus, hondas, and such having bouncy suspension?
IT is really noticeable during gear shifts. Is this caused by bad dumpers? Or maybe coilovers?

They have soft suspensions, made for drivers who don't care about sporty handling.

Its what happens when the spring is too stiff for the shock/strut.

And one would assume that the spring stiffness could be checked by looking at datasheet/specifications?
I did change springs to H&R race sport, and I will hate it if they are stiff to the point where car is bouncy.

As long as you replaced your shocks and struts with ones that can handle the higher spring rate you'll be fine. If you kept the OE ones like the Honda guys do they'll quickly blow out and you'll end up with no damping too.

They most likely have cut springs, are lowered way too much or have blown shocks.
