I expected that...

I know this also, but to be honest if crash is strong enough to come to inside of strut tops, it doesn't matter if other side is affected

Of course, it's a more expensive solution...
I want to change anti-roll bars also, but they are difficult to get (only Autodelta has them, Novitec and Eibach don't).
There are available anti-roll bars for 156, but not for 147 (it seems that reason is because they are hollow).
I can't lower my car for several reasons, so I will not change springs, probably I will only change front dampers (Bilstein or Koni).
