I understand what you are saying about removing the adjusters and match them. But I don't think it is possible to do that with these dampers anyway. The adjusters are a one piece thing and can be rotated from fully open to fully closed and the knobs cannot be removed, so adjusting it like you said does not seem possible to me.

If you would want to match these dampers you'd need to fully build them, dyno them and if they are not the same you would then need to change the shims in order to get them completely equal, which would be an iterative process. It would take quite a long time as well, as each time you would need to remove the piston from the damper to revalve and then fill the damper, bleed the air, fill with nitrogen and re-dyno the damper. So I can't imagine they would do such a thing as standard. So I guess (hope?) that the shims have very tight tolerances, so that the damping would be equal by just putting the same shims in.
