For some reason I can't edit my post. That site is Slovakian (explains why the catalogue is in German and English) not Swedish (it would probably be in Swedish then!).
That site with all the trinkets above (chrome rings, etc.,), unofficial "mods" and so on: CKS Performance in the UK do all of those ones as well (wooden gear levers, etc., ).
Personally, I'd keep it as stock as possible.
