Think of the kite you're flying, darting around the dky, out of control.
Then take an old bedsheet and tear it in to strips and make a tail.
The kite settles down.
Think of going very fast and the road gets loose and floaty.
A tail on this kite amounts to a slight application of the E brake.
Rear wheels only, pulling backward, so the fronts can concentrate
on directional stability.
Weight transfer is very significant in the braking performance of a car.
The rears act to hold the car straight while, with all that weight on
the front,
the front wheels convert momentum into heat. The rear brakes function as
a
drag to keep the vehicle straight.
Spridget percentages of brake work front to rear, I would estimate
up to 70/30 and, for a Mini Cooper, 75/25 or 80/20.
Discs in back are an ego thing.
