Eibach, acs and h&r have springs deigned for the size of engine and therefore weight of the car, just buy the correct springs for your engine type.
Eibach make springs in Germany and USA, those manufactured in Europe, assuming for the European market are tuv approved. TBH I would take the approval with a pinch of salt all there springs are built to high specs, not heard of them breaking on car where used for their intended use, e.g. Road.
