In the time you could get a full set from Koni it used to be Eibach springs, but I don't know if these are still Eibach springs. I also find it strange that I can't find this kit on the Koni website.
I have had The yellow Koni front shocks fitted with Eibach springs on the front and Bilstein rear shocks with Eibach springs for a long time and have not had any problems with them.
