so, i put the threaded collars on my bilstein shocks today and i made a few observations.
can anybody please confirm/deny any of this: - collars seem to be "tapered" inside, the bottom part has only a small amount of play while the top moves at least 1mm side to side - the bottom of the collar DOES have some small amount of play. this concerns me as the "ring" it sits on is tiny and has to support the whole weight of the car. is this normal ???

Yes, the OD of the shock is smaller that the ID of the collar.
As I recall, the 1 mm is about right, but closer to .060. It seems less below as the keeper ring is a better fit. If you don't shim the collar/body interface it may get screwed up from going off center and working by the keeper. I used plastic shim stock cut to wrap around the shock body....full length, keeper to top of collar. One layer of .020 & another of .010....but it may have been .005. A pair of calipers is your friend here. I'm more surprised that you didn't complain about how the spring hat fits. I had to do some serious rework to make the top fit properly. These are from Colman.
