For those of you that seem to be trying to down play the need for better braking in the rear: Yes, it is true that well over half of the braking is done in the rear, and I am sure that a car with an improved stock setup(ie better discs and pads only) will not benefit as much as those with larger front rotors. I have the Baer big brake kit, and let em tell ya' I NEED MORE REAR STOPPING POWER , and if I said my desire wasn't slightly aesthetic also, I would be a liar.
