you're missing some of the benefits there chap. While i do disagree on your point there is also the fact that the disks are thicker, and pads and calipers larger. That meaning the increased material is able to soak up more heat and continue working optimally for longer after repeated breaking applications (at least for longer than the smaller calipers can take).
Fwiw - i went from 4 pots to brembos, and by the seat-o-pants-ometer i believve they able have to haul up faster.
i too agree with you with this funky and a few other guys that had upgraded from 4pots to brembos. there are some others that say the same thing about the 4pots but really on the track its kinda a piece of mind that your brake wont failed you. its all about brake fade due to heat. I yet to replace my Project Mu i900 pad as its killing my rotors effetely.
the disavantage of the brembo is that the rotor is heavy but it is almost twice the size compare to the wide and its got a larger venting between the rotor plates compare to the 4pots and it looks good. i know for the fact that my car stop way better with the Brembos over the 4pots
people do what ever they want to their car.
AP setup probably cost over $3000 vs Brembo setup around $1000. Bang for buck i think everyone will go for the Brembo, well unless you work in the IT business can afford to spend shid loads on your car?
