The power of a car however bears little resemblance to the speed that it slows down at, only the weight.
A 1500kg 500bhp car slows at the same rate as a 1500kg 250bhp car
you're right chris, but the 500bhp car is going much faster at arrival of the corner so needs to slow down more to get around it at the same speed.
and you all have a point that bigger brakes allow you to brake later and harder, bt only if you're doing this often and the std brakes would be overheating. if it's just one application, the std brakes will slow you down just as well, although you may have to put in more effort on the pedal. the grip on the tyre is what limits the retardation rate.
