The answer to why enthusiasts perform any performance upgrade is basically the same. Personal driving enjoyment goes up when the envelope of dynamic vehicle performance is increased. However braking, more than any other performance aspect, has the additional benefit of actually increasing vehicle safety and thus helping to protect the enthusiast's overall investment. Better braking on a road course can mean the difference between first and tenth places; on a twisty back road, it can mean you can run the length of the road without fade; in an SUV loaded with your family, excellent brakes can mean confidence and peace of mind. Whatever improved braking performance means to your personal requirements, please remember, when you do find out first hand that you need better brakes it is most often… too late!
Find yourself in need of an emergency stop and suddenly, what is normally a decent stopping vehicle, seems to take more real estate to stop than a fully-loaded freight train on a cross-country run. Installing high-performance brakes can shorten those distances tremendously, cutting 20 feet or more off a 60 mph to 0 stop. While 20 feet may not sound like much, imagine what it can mean in potential property damage, or worse, injury. Most would agree that normally 20 feet in an emergency can be the difference between a big problem and a little adrenaline rush.
