Hi Johan, I see you are picking away at the winter to-do list.....
One thing that strikes me is that if you've had to roll the fenders, already, anything you do to fix this issue at the top of the strut is going to make that clearance tighter. I wonder if you should look to the other end of the strut?
One easy (depending on your welding skills) solution would be to shorten your A-arms by an appropriate amount. Definitely want to measure twice
It seems people commonly lengthen them to increase camber so I know it's possible.
