Hi André,
Unfortunately I failed to made this plan reality. By the time I was really in need of new suspension there wasn't any kit available or I fail to find it online on ebay or refused to buy used one and import it from JPN. It was 3 yrs ago. At the end I select kind of oem style (street legal) set/kit from pedders.
Not sure if it is TUV certified as oem replacement for DE. But I never had an issue with Czech Technical inspections since then. I can tell it was ok feel, not much better from stock. But what was worse, when carrying really heavy loads in trunk, the handling worsen. I mean really heavy load, over the capacity. The read end dig down and front end lift up like starting airplane feeling very light on steering/handling. For the rest of occasion it was ok. I sold the car last year with 30k km on that shocks w/o any issues.
