I've tried the Kolbenrückholfeder of your shops non-ai-predecessors fame: https://etel-tuning.eu/produkt/tuning-kolbenruckholfeder/

Didn't work out that well, sadly. At first it gave me a greek pillars, then when trying english translations it at least gave me some springs.

It knew the https://anycrap.shop/product/airhook. But only for light loads like snacks and the "heavgy duty airhook" it wanted to sell me is for a clothesline. While useful, I'm afraid your product engineers have to spend some more time so that we can reliably suspend cars from the air again.
