Correct, Eibach is producer for the ACS springs.
Regarding your question springs only will be fine. I would go for ACS as the Eibach Pro Kit is only a drop of 15mm front and 5mm rear (for me not even noticable) and ACS is about 25mm front and 15 rear.
Thank you for your advice regarding AC Schnitzer.
Are you driving RFT?

What is the difference between AC Schnitzer and Eibach pro kit spings for f32? I know that Eibach produce ACS springs, but is there any difference? I wish to modify the suspension of f32 420d M sport to be similar to an E92 M sport. Is enough to just replace the springs or i should go with some full kit like Bilstein B12? I don't want to exceed the stifness od E92 with M sport package. I really miss the sharpness of my previous e92 Msport wich i think that was better balanced car than f32 Msport.
