This section has been mainly descriptive, but it is possible to account for the weight transfer to solve numerical problems. To make matters simple we will treat the car as resting on only its outer two wheels (this is really a motorbike approximation).

** Example** An F1 car has a 60/40 front-rear weight distribution.
It is cornering at 1.4g but the rear tyres are capable of producing a total
of of traction (where is the weight on the rear
wheels). The design is such that 20% of the weight is
transfered from rear to front per 1g of braking force. What braking
deceleration can the driver apply before the rear tyres break loose?
[To make the problem simpler, assume that the front wheels do all
of the braking!]

** Ans** The maximum weight transfer is 6% from the rear to front.
This corresponds to 0.3g of breaking (Part III). Play with the calculation, and
you'll see how critical it is to ensure that the weight transfer
is as small as possible. This means getting the Centre of Gravity as
low as possible.
