Does this fit the way I imagine it???

Hello dear people, I have a few little fine questions where I know a little bit but the hangers are missing me. To explain: Of course I drive a VW FOX. I started to do something about it a year ago.16 inches wheels deeper but only with springs still no complete suspension. Next week should be something more!See now! Rims: 7.5 J x 17 ET 35 Tires: TOYO 205/40 R17 Lowering (feathers only) 45mm currently (later Weitec threaded chassis) Distance discs Rear n: 15mm Jetz my question has it all together?Can you say it like this? so mature fit according to rim reviews to the rims of therefore I have no problem there. but the rest? e.g. can I turn the 17 inches rims into a 45s spring depth laying? Would be nice if you could think about it briefly. My second concern is: What kind of papers do I have to take with me to the TÜV???have many things but give me a few tips, which I should never forget, so I can get through!!!! Hope you can take a little time for my care… thank you already and love greet FoxStar
