Having had a lot to do with both f**king fast cars and heavy mining equipment I can honestly say that braking distance is more dependent on the following than outright speed:
- The equipment you have to pull you up in time (stock shitty brakes versus something from the HSV, FPV or Brembo stables)
- The type of rubber you are using
- The weather conditions at the time
- The rolling resistance of the surface you are braking on
- The type of brake pad in use (long life cheapos, high po expensive or highest po f**king expensive but non working at lower temperatures)
- The weight of the object you are trying to bring to a halt
- How many times you have stamped on the brakes immediately prior to the "hard" application (fade etc)
Sharko, just because you keep hearing it in an advertisement by some self appointed crash expert does not make it true, if I were to take you for a spin in my twin turbo'd car and jam the brakes on as hard as I could at any given speed in optimal conditions it would be enough to jolt the absolute shit out of you and possibly throw you through the windscreen / into the dash if you were not wearing a seat belt.
It took me less than 2 seconds to go from 130 to 0 before I had the brakes bled and freshened up a week ago , I would test it beyond that but neck injuries suck balls.
On Carney - dickhead.
