I have sort of a odd question that came up from researching how to properly setup a weight distribution hitch.

I'm looking at this post from PAX5 -> Bimmerfest - BMW Forums - View Single Post - 2013 BMW x5 - Trailer hitch recommendations?

It shows a hitch height for the OEM hitch of 16" from the ground to the center of the receiver.

I went out and measured mine and it turns out to be 14.5".

My car has the following suspension options:
S2VAA - Chassis & suspens. setup"Adaptive Drive"
P330A - Sports package
I don't have third row nor self-leveling.

Would anyone be able to clarify whether or not different suspensions setup result in different height? I was under the impression that the sport package suspensions would just be stiffer springs, but not resulting in a ride any lower than the regular.
