Unless you load the springs past their yield strength (which you won't be able to do) you won't have any "static memory". As for the bushings, they hardly rotate during a drive and the roads that they were designed for they barely move during a normal drive so I wouldn't be concerned about the fact that they are static......

IMO.... What I would be concerned about is having a car sitting on 4 jack stands creating stress points on it's frame for months on end when it was designed to sit on the wheels. Flat Spotting will be the least of your issues if you keep straining the chasis by leaving it on jack stands for a long period.

???? I place the jackstands under the approved jack points specified by the BMW engineers. You're telling us that BMW specified jack points will cause damage to the chassis when subjected to vehicle load?

Lol. So what we have been doing for the past decade is wrong? And what my father has been doing for a couple of decades before that is wrong? Yea, no, I will disagree. Put the jack stands in the correct spots. Frame damage, this isn't some 1940s car with no jack points or shit metal.

Memory, as in those bushings and mounts get constant pressure in the same spot with no motion. Even the little motion that they are used to. Again, been doing it forever, so not going to stop this.

Starting in the '80s/'90s BMW has lead the way in regard to finite element analysis and nonlinear dynamic analysis. Put jackstands under the most convenient place under your car and carnage is sure to ensue.

I've been putting Trans Ams, Mustangs, Vettes, Vipers, BMWs and other vehicles on jackstands in my garages for over 30 yrs and not once had any damage/issues.
