Spring selection

I want to attach a bow to my car, but I had a bow in my previous car, and knocking sounds were coming, just because of that I sold it, but these springs were cut out, now I want to wear xtye bow, which brand do you think should I wear and I wonder if it sounds more than knock sounds and the current construction of the car?

I prefer eibach

Let's open our topics under the appropriate headings, please ...

Knock sounds should not come ... I also have 50 mm spring and no sound :)

friends, if you pay attention to the topic you opened with different topics, I would appreciate good forums.
