Weight distribution vs handling - questions

[mariano]

I read that thread, but I didn´t understand anything. If in a F1 car I put more front static weight, and I am cornering without brakes or throotle, will it undesteer, or overteer?

And if I trail brake or unwind (while acelerating)? Will I have to turn more or less (add or remove steering wheel)?

Thank you in advance,
