What model did you have them on?
Eibach USA says they‘ve not been “ verified “ for the US or Canadian market for a 982 although I’ve seen pictures of a 982 in Europe and the box does say 982.
What's interesting is that in another thread, the seller here on the forum showed a picture of the box. Same exact part number and it indicated it was for 981/982 Caymans. I believe these are interchangeable parts and am not sure why some sites don't indicate this.
