Hmmmm, no difference so far... I did the pad bedding which took most of the afternoon. The pedal is tight and the pads are silent, which was my biggest concern going with bigger brakes. I have nothing to compare them too though, I never experienced brake fade before and I don't think I ever got my stock calipers hot enough to melt ice, lol.
It was just a cosmetic gift for the car, an expensive one but I LOVE the way it fills the wheels.
