It is adjustable, just NOT USER ADJUSTABLE. If non adjustable totally cannot change your soft hard.
Comparison, if you get a 4WD truck, there are 2 types, one is shift on fly 4WD one more you need to slow to certain speed to shift into 4WD mode, does it me the truck NOT 4WD?
You need to get back to them to make it soft or make it hard, and the hard setting is really hard, I believe as hard as any other hard suspension setting out there, I tried their medium hard setting, the whole car is rocking on a road that looked perfectly flat but the steering response is very sharp. They could throw my T1R out of grip during turning with that setting with hardly any body roll. Now my setting is medium soft and still no one can push my car down with their hands
