Most of the weights in any modern BMW are in the sound insulation and stock seats. And unless you racing competitivelyp, it would be just a waste of money. If you want faster times, spend the money on sticker tires and better driving skills instead.

Maybe the OP won't be completely stripping out the car, but other people will be. It is extremely useful to have this resource here.
I race in series overseas that use production cars, you are allowed to take certain things out, others have to stay. At the same time you add in weight with a cage etc. Also, the car has to comply to a minimum weight. If you are building a car for series like this it is extremely helpful to have a list of weight of all kinds of components. It may help you decide whether the car is going to work within the regulations etc.
Previously when I have built rally cars I have documented the weight of everything that comes out of the car, down to things like sun visors, small plastic trim panels, seatbelts etc etc. It provides others with a great resource
Thanks to the OP for putting this together. It is greatly appreciated
