I know the rear brakes don't have that much to do with it, but it was an example of stopping force. More stopping force = more nose dive = less weight on rear tires to make them chirp. Not scientific but it gets the point across.
A lot of people like them, and a lot of people don't. They would say they're over rated, including myself. If you were going for all out bragging rights, then it's fine. But the pedal feel is too squishy for a daily driver for most people to be happy with. I like my brakes sensitive and quick to respond, which is what I have now.
The total piston volume is larger, BTW. We have guys who work at brake shops who install them (totally bled by a machine) and still have the less sensitive pedal feel. The only real benefit I see is that the pad is larger I believe. But, like I said, I'm happy with how mine stops.
