Lou,
It's not wise to make generalizations about the handling of a car based on something as simple as weight distribution, but here are a few thoughts about the GT40. For accelerating, the more weight on the drive wheels (rear in this case), the better. When braking, the effective weight transfer to the front means a car with more weight on the rear will become more balanced under braking. And for a car with significant aero downforce, that force can be used to balance the actual weight of the car when cornering at speed.
