You can order the AC Schnitzer lowering springs with TÜV certification for the Supra and they are just relabeled Eibach Pro ones. And they are available for 370€ without shipping.
This is what they look like.
The picture from eBay and from the shop is not how they look like. The picture I posted are the real Eibach Pro Kit ones.
But it’s wrong even on the Eibach website.
