@ZDan Have you checked these ones?

They are co-developed by Bilstein Germany and STI Japan. Funny thing is that I was living in Germany and I had to order them from Japan, because Bilstein Germany does not provide them in the local market.

About specs:
They have a longer front strut which gives more bump travel. They might look similar to Bilstein's B6 suspension, but the internals and valving are different.

Springs are not that stiff, but among serious damper manufacturers there is a concerted move back to softer spring rates. STI is not providing the exact rates. Comparing to my previous Sachs adjustable coilovers (Front 38.50N/mm, Rear 42.50N/mm) they feel softer and more compliant.

Only "issue" of the suspension is the height of the car which is about 0.6" lower than stock height. So, I would say a bit close to stock height. If you are looking for a lower height, then you might not like them.
