Power to weight, brake to.......

[nikkinokkinoo]

I know the measure of Power to weight is used and makes sense. But there seems little on the subject of brake to weight. It would be an interesting measure of a cars braking ability to know the brake surface area to that of the weight of the car. I know that different compounds of pad's etc will impact stopping effect + 4 v 6 pots, but as an indicative measure of how well a car will stop I think this would be a good thing to know.

Thoughts on a post card please

Also need to know sensitivity of servo assistance.
Fluid type will also effect. If using racing fluid such as racing blue, the temperature has a huge effect on performance (a negative effect unless at racing temperature)
