The easy part of the project is the Stamp and the LCD display.
The load cells or whatever you are going to use for the wheel 'Scales' will
be the expensive part.
The average race car is around 3500 pounds, (Stock car) so each pad will have
to support 1000 pounds any way. Add the extra punishment that will have to be
absorbed while driving on (The higher the finish the faster the driver may be
going!) A rough guess is the pads will need to be designed to take a ton
each. More if you are into monster trucks.
The percentage calculations can be done from the separate wheel weights and
just handled in software.
As a second thought, a less expensive system could be made with 1 wheel
scale. Just put it under 1 wheel @ a time and you get the same results, but
it takes 4 times as long to weigh the car.

a perfect flat surface. The cars I want to weigh are pretty light "below 500lbs
each wheel". The load cells are pricey. If any one has suggestions on how to
build or buy them cheap please let me know.
Thanks,
