Alfa 159 Suspension

[Alfisti]

Dear Experts

I'm going to change the suspension of my Alfa 159 due to some rattles coming from front right and rear. Issues only lies with the front arms and the 4 top mounts. However, after a discussion with ITMC, I decided to change the dampers also to ensure the new parts will not suffer by old parts (the mounts are quite expensive). The choices I have for dampers are as follows;

1. Koni yellow sport adjustable

2. Koni FSD

3. Bilstein B4

4. Bilstein B6

I have been using Koni yellow adjustables in my Alfa 156 and they were quite good. But they were a bit stiffer for the comfort needed for a daily drive. Bilstein B4 is the OEM replacement but it is twin tube whereas others are mono tube. Now it's not everyday we drive like maniacs and only once a year we have a track day. So day to day comfort is also an important factor.

Can you enlighten me with your experience with above choices?

Thanks a lot in advance

Bilsteins or Yellow Konis. FSDs seem unsettling on our roads.
