Where can you find OEM BMW spring rates (i.e. in lbs/inch or its metric equivalent). Is this proprietary info?

Sorry for being an idiot but
OEM BMW "spring rates", as in bargains, must be available now when the the facelift is coming...

Of course the measurements of parts and their constructions are factory secrets

There's a lot of reasons why the copycat Japs and Koreans hasn't yet got to the BMW level...

I am asking because I really liked the stiffness of my previous BMW and would like to know what the spring rates were to compare it to the 550, and then naturally to some aftermarket springs I am considering for the 550.
