Great deal on M3 big brake kit

That's pretty sweet looking.

Here is a question that I have been meaning to ask.

Looking at the specs from the various Kit car mags that have tested the BDR, the average breaking distance from 60-0 is around 150 or so feet.

Since braking is, from what I understand (and I understand little), is mainly down to the inertia and the friction, so basically the weight of the car and the grippiness of the tires. Most if not all brakes can lock of the wheels, so braking at least once, not racing, is not very dependent on the "quality" of brakes. So a cheapo brake that can lock the tire up is as good as the Brembo F1 series. I find the hard to believe, but it does make some sense.

My question is, why is the braking distance so long. Weight on the Cobra is extremely low, and the tires are relatively wide and good. The Honda Civic 0-60 is around 130 feet, a M3 is around 110 feet and the Corvette ZR1 and Viper ACR is pushing sub 100 feet. A Honda Pilot is 150 ft.


What gives.

I am sure there is an easy answer, I am sure brake bias is part of it, but seems like if could shave off 50 or so feet, every car would be set up that way.
