ok evan could show a little more tact but he's making a lot of valid points. before anyone jumps on my case i HAVE aem 12.5" xdrilled/slotted rotors with GSX calipers. the rotors don't really do shit. the main braking improvement i've seen was due to upgrading to gsx calipers. our stock brakes suck. that's a fact that few would dispute. however, big rotors are not necessarily the answer to the problem. yes your brakes 'feel' like they grab more. a lot of what people associate with performance is the amount of pedal travel required to break your tires loose.

think about that for a second

the fact that your wheels lock with say half pedal now does NOT mean your braking has been improved. better braking is associated with decreased stopping distance and increased resistance to fade. pedal travel really has nothing to do with it. really all you've done is DECREASED your ability to properly modulate your braking. instead of many degrees of between zero braking and full braking you now have ON and OFF. not good.

a true brake upgrade kit must analyze the entire braking system of the car as a whole. your front and back brakes are not independant. did you know that by making your front wheels lock up sooner you have actually increased your overall stopping distance? that's bad. this is due to the fact that your rear brakes are no longer being brought as close to their threshold as with the stock braking bias. an ideal braking system bring all four wheels to their breaking point at nearly the same time. this allows for a minimum stoppping distance and maximum control throughout the deceleration.

evan - be nice and maybe they'll listen and learn something
