Need rim advice, TÜV, registration? – Audi Coupé

Hello community, I’ve been searching for a while, but I haven’t found any useful information yet. I’m looking for new wheels for the summer. But now I don’t know which width of the rim I can go to without working on the bodywork. Would it be 8.5J x 17 VA and 10J x 17 HA too wide? Furthermore, I have no idea how this works with the registration of the rims. For my RH I only have an ABE. In which cases you have to enter the rims and how I hope you can help me a little. lg.
