I have the same ones installed in my Eibach Springs.......
You should have gotten a little bag of parts with them. It will have little clamps that go around the hose @ the bags, and at the filler adapters. They are brass, and look EXACTLY like a valve stem on your rims.
Most people start with a 5 (that's the MIN. you should go) in the DS, and 15 in the PS and adjust from there, how much you adjust will depending on track and tire conditions....
