Who makes yellow springs?

[bobbytomorow]

I want to lower my e30 a little more but I cannot identify the springs that are currently on and the PO is no help either. Any identifying marks are rubbed off but I need to know how low it is now in order to know how much lower I can go, or rather I don't want to buy springs that will be the same height or higher.

I have Bilstein Sport shocks/struts and all I can say about the springs is that they are yellow...Some searching online brings up King brand springs...is there any other brands that make yellow springs for our cars?
