Hi SW Germany!

I moved to Germany (NRW) a while ago, but don't really speak German.
This makes life interesting at times

After having dealt with German insurance/KfZ bureaucracies I have another question.

Last week I bought a VW Passat estate in Aachen (Jacobs gruppe) but have a question about lowering. Can I just install a "TuV" approved coilover kit for example H&R monotube?

Or do I need to have special paperwork for the lowering kit as in other countries?

And are there other SW members in the NRW area?

Kind regards,
