Does anyone know much about this?

From what I've seen, I can only find applications for E90-series BMW and such like.

Do they not, or are they not planning to do them for other cars? In particular, Imprezas

Got it in my Maser if we're talking about the same thing.

4 electronically controlled suspension damping settings, controlable with a switch in car whilst on the go...

 

Basically, yes!

 

What do you want to know?

It's controlled via pushbutton with 4 settings with 1 to 4 led's showing to indicate what setting is active.
You can change setting at any given speed.

Setting 1 is so soft the car wallows
Setting 2 is nice and firm, it's the standard setting when you start the car
Setting 3 is very firm
Setting 4 is ridiculous, very harsh ride, you'll feel every ridge in the road.

Costyly when it breaks as replacing the complete shock is the only option as far I'm aware.

 

I wanted to know A. What the settings are like, and how different they are, which you've answered just nicely

and B. Are they going to increase the range past the few cars they make them for at the moment.

I'm guessing your are standard equipment for your car by the sounds though?

 

It was an option on certain models, the racing and the ultra rare 4V (wich is the one I've got incidentally).
