From my research the issue is shock valving. Non adjustable Aftermarket shock manufacturers are specking their products close as possible or even more aggressive than BMW specifications. An adjustable shock will give you more flexibility in dialing your comfort level.

It’s important to note that there are a few issues with adjustable shocks:
1) Are they even made for the E53?
2) Shock adjustments only impact some of the valving. Even a full on 4-way adjustable shock is somewhat limited in what the adjusters can do. (Note: Notwithstanding some marketing, there is no such thing as more than 4-way damping adjustment. Many manufacturers have taken to counting clicks in the knobs as a “way,” but that is a fucking lie. At most, you get low speed rebound, high speed rebound, low speed compression, high speed compression. And you’re generally talking about $10k for a set of actual 4-way shocks.)
3) Don’t assume that an adjustable shock can be adjusted softer than stock. Even when they are made, most adjustable shocks for BMWs start stiffer than stock and end up MUCH stiffer.
