I don't have or claim to have anywhere near the experience that that some of the track junkies here have. Which is why I brought this is up for discussion.
Maybe it's me being a bit thick, but from what you are saying I am gathering that the piston surface area needs to be within 10% smaller to see an improvement ? Well just with the fact that it is now 4 piston instead of 2 piston on the front, that surface area would be almost doubled (right?), At the same time however the surface of the pad is smaller than the OE pad so the contact patch between the pad and rotor would still be smaller.
