Intrax coilover suspension for Micra K11

Hallöle, have before me for my K11 (1,4 ; 3doors ; BJ11/02) an Intrax coilover suspension to be installed and possibly installed at Becker in Hamburg. Does anyone have experience with this chassis? Have the following tyre size: 195/45/R15. Is it necessary to pull the wheelhouses and to bulge? I was also told that one might also need ́ne track widening and limit spring travel limiters, steering strokes, … and, and, and. Would be great if someone could give me some information. uch not so little with 1150,00 Euro + installation + registration. *grins* Is there Becker in Hamburg at all? On the homepage it appears to me so, but in the car picture or the ADAC magazine was advised not by Becker 1 – 2 year ago, because he allegedly should be broke and no more works should have been carried out … Ciao. I am grateful for every information ;o))
