The pad surface area doesn't look any bigger then the 2G pad areas. Also the calipers arean't much bigger. But it looks like the main gains are a much larger rotor to disipate the heat and the fact that the clamping force has been moved much further from the center of the wheel.

They also fill in the wheel much better then the stock setup. It no longer looks under braked .

The Hawk HP Plus (not HPS) bite great but do squeal a little. I forgot to use any smurf juice so that might be why. I'll probably pull them off and goop them if it bugs me too much.
