Hello,
Could somebody please explain why adding weight to the rear of
the car makes the car loose? Why doesn't the added weight make the
wheels grip more?
thanks

Because the amount of mass that has to accelerated by the force
generated by those tires increases ever so slightly faster than the
tires' ability to generate frictional forces.
(Your physics teacher taught you that the coefficient of friction
between two substances doesn't vary with normal force. She lied, but
just by a tiny amount...)
