A guy that I used to dune with worked for Eibach. He made it out like they made springs for just about everyone.
Could be they are just custom labeled Eibach units.
The high school I went to had team colors of purple and gold. My senior year my hair was probably a few inches below my shoulders and bright purple.
My football coach hated it. Everyone else on the team shaved their heads. LOL
Your first example doesn't have 87A. There is no NC to common contact. It's 2 87(s). It's just multiple outputs when triggered.
This is not ideal for running multiple fans.
