Problem :Which suspension without mortaring and pulling

Servus you dear Leut, now it is finally time, now with defective rear shock absorber I have now all reason in the world to exchange this SChwamm suspension for a sports suspension. I wanted to hear your opinion, because here are many already equipped with mehfach suspensions. To me a quite sporty abe nevertheless comfortable (much AB) simple sports suspension without a thread (do not use anyway) before. The lowering plays only a subordinate role for me. I don’t know exactly what exactly fits there, so I wanted to ask how much goes without bodywork (at 185/55/14 and 175/65/13 ). As a suspension, I currently have a Koni with Eibach feathers or a Bilstein B12 cup ( 20 mm) in stock. Unfortunately, H&R Cup kits are only available from 50/40. So lower than 40 mm I don’t want to mount it then I think without pulling it. Maybe you have some ideas about what you could do there. Would be very grateful to you. The chassis should be price-wise (everything depends on the price today) so move in the region up to a maximum of 550 incl. dust caps and attachments. So en billichschißdreck from EBay for 200 Eus is absolutely out of the question…. So I think you should get something decent for this. About tips and suggestions I would be very happy. mfg lüpo
