I just put them on the car yesterday. The install was a breeze (I was suprised how easy it is to change a rotor) and of course I kept the speed down since they have to break in, but the pedal feel is much better, and the car stops better, it's much smoother than my beat up stock rotors.
I'd get them if you're looking to change out the old rotors (I've got porterfield r4s pads with them)
