Ok, new updates.
After installing Eibach Pro Lowering Kit, -20mm back, -25mm in the front, I also added spacers. I added 20mm in the front and in the back - also Eibach.
The end result is just incredible, but don't listen to me, take a look at the pics.
It doesn't rub anywhere, the camber is now -1.5 on both front and back. Rubbing, or better said - scraping - only occurs on steep slopes and it happens on the front rubber flaps (in front of wheels), but can be mostly ignored, as nothing happens, other than it slightly scrapes, and does not happen often anyway. It can be reduced with 45° approach, but mostly doesn't help much.
