30mm drop doesn't really mean 30mm, It will vary from manufacturer to manufacturer, so there is no answer to what the camber will be after fitting.
When I fitted "30mm" K Sport springs, it was more than 30mm and the camber was out of specs by about 2 degrees, so had to buy SPC/Eibach camber arms to adjust it within specs. Eibach springs may be fine, Apex may be fine, you won't know until you fit them
