M sport is deffo not the same as eibach pro. Here is the catch tho - unless you have a heavy front end like 335d or i then you might suffer to get a noticable drop. Everyone who complain there is no drop in the front are not with a heavy block. Whereas me n several others who has a good drop in the front are 335i drivers or heavier engine's. Hope this clears things up.
P.s i really don't notice any rear drop
