I installed a set of 350Z rotors and Hawk Pads and dropped 18 feet (from 134 to 116 ft) in my 60-0 distance (according to the GTech Pro).
And if you ever do decide to run your car at a track, the setup will work well. I was able to continually drop from 130 mph to 30 without a hint of fading.
I am sure that there comes a time when this setup will not keep up with the bigger HP track cars, but I did see it do quite well on a car that dynoed 451 HP.
