It's a perception thing because they are not power boosted. Most don't reall=
y need the brake change and a poorly executed swap is the worst thing you co=
uld do. On the track the larger area of pad and bigger disk to absorb and d=
issipate the generated heat may be of value. But many racing classes don't a=
llow a major brake change. Most drivers will never go harder than the stock=
brakes are capable of handling anyway. With good pads It takes several real=
ly hard laps of really hard braking to get beyond them.=20
The braking effort is limited by the tire contact patch and friction generat=
ed there. If you go to much bigger rotors, really large area of brake pad c=
ontact and then much bigger sticky tires, a bigger brake set up can be of us=
e in high performance driving. Otherwise the stock brake set up is pretty g=
ood if you keep them maintained and adjusted properly. =20
But what the heck do I know. Truth of the matter would be G force and dista=
nce tests, stock versus modified but each with the same tire set up.=20
