Why can't a person use a degree wheel like people always have?? lay it on the flat part of the ski, see what the degree is, I would think around +2-3 degrees. I don't see how hanging the suspension in the air checking the camber, can relate to how the ski lays when under weight with camber? You don't ride or turn the sled with the skis in the air? Is this a Polaris part they want you to buy?
Just a observation.
