What about moving the inner pivot of the suspension arms upwards?

However, more front rollstiffness will generally tend to more understeer.

Its already on the upper one of the two holes on that bracket...and there's no room to go even higher. Trust me, I've looked, but good thinking and tnx for thinking with me

Hmm, I had forgotten about that effect...damn!
The balance is actually pretty good. Its just that the front tires seemed to have suffered more then the rears and on one very tight corner, I wished for a little less understeer, but maybe I should have turned in later there..

It's tough to tell from the photos but the inside front tyre looks a little light in the bends. In other words, the inside front is not planted and the front grip is mostly relying on the outside tyre.

It looks like the outer rear has compressed a bit far leading to the inner front lifting (the diagonal effect). I'd suggest a slightly tighter rear antiroll bar or perhaps ideally, slightly stiffer rear springs. A looser front bar might also work but more lean has other issues.

You could also try increasing the front rebound and see if that helps.
