Double your speed, double your braking distance.

Chris, you need to refresh your physics. Your brakes can only dissipate a certain amount of energy at a given rate, even if they can continue at full capacity (no effects from fade/heat). From 70-100 the energy (momentum) you are carrying doubles. Thus, you must dissipate twice the energy.

Formula for braking distance: V^2 / 2*u*g

u (mu) is the braking friction coefficient, combination of the tires/surface/brakes. g is the force of gravity. So, the denominator being equal, increasing velocity has an exponential effect.
