Where in the world did you get this info?? Sachs/boge is the OE supplier for E46 platform, non sport and sport. Bilstein is an aftermarket company just like KONI.
Meyle HD are great products for the ball joints and bushes, highly recommend over OEM, and they can be used on sport and non sport suspensions... Shocks on the other hand, for lowered cars, you need to find use the appropriate shocks that will withstand the extra travel. Sport suspension requires sport Sachs struts if you go OE. If you want to save some $$ go with KYB GR2 which will give you same performance for stock sport springs. Anything lower then stock, you need to use KONI or Bilstein sport or HD struts to maximize the lifespan. Anything else will be a waste of $ and time.
