This thread has drawings of the shims I'm after:

So they are kinda like the washers, but just a little better I guess.

Of course modifying the mountings could be a possibility, but these shims are effective also so I'm not too keen on starting with the cutting and welding.
And yes it's not legal here in Finland () but I'm not too worried about the inspector noticing these at all.

Front camber isn't really an issue, so I'm not planning on adjusting it. In rear it is more of an issue, because when lowering I'm going to loose the traction needed to put any power down if I don't do something for the camber.

I might invest for a proper adjustable suspension some day, but currently it's out of my budget.
