Cusco coilover question

[driftkid316]

So i just picked up some coilovers and had a few questions since I've only owned one set before (Tein winding masters)

The person i picked these up off of indicated they were Cusco Zero-2 coilovers. From researching, these should have a 5 level dampening adjustment. But looking at the coilovers, i dont see how I can adjust them.
Did i get duped?

There should be an adjustment knob on top of the nut. They could also be Zero 1s. Doesnt really matter since those coilovers are worthless since they are only 1 way height adjustable. Car will ride like poops the lower the car gets since you're also changing the dampening and spring load. Had a set a absolutely hated them.
