finally landing gear!!!

hello juhuu, finally it’s official… I’m going to do my suspension installation and bring my treasure 60/40 closer to the earth… I’ve got a few questions to ask now. 1. Which chassis do you recommend to me? it should be cheap, and so that I don’t have to do much (best garnix) with my tire. so pull and so… my tire is as follows: 7×15 with 195 45 tires, that at all without doing anything? 2. what do I need next to the chassis? domstreb e etc.?!? 3. where do I make the installation the best and fastest? because I am dependent on my car and can not really spare that long. the self-installation I don’t really trust myself and I have heard that the vw workshops are not really happy if you arrive with shares and want to have them installed. supposedly they beat right then and ask for the cash.. 4. do I have to pay attention to anything else? many thanks in advance already for your help..
