Even using the lightest one piece rotors I could find brought the total  down from 56 to 44 pounds for the rotors. Now if you used a 2 piece setup it would be lower but not by much because the width of the calipers is made for a thick rotor and the car it is made to stop is 4500 pounds. I went though several pad selections trying to match the cold bite of the Hawk HP+ pads that I was used to. On the track the highest rotor temp I could get was less than 500 degreese. The stock Ford pad worked the best for cold grab but they are really dirty and track time requires the windows down. The Ford dust burns your eyes and sweaty skin more than any other pad I tried so between the unsprung weight that is a cubed function for the front end suspension and having a car that was too light and slow to generate the heat to make pads work I went back to the Cobra PBR front and rear set up. Now all this could be moot if you do your twin turbo engine and are trying to stop from 150 MPH.  I have a S197 front set up to try but a smaller thinner rotor would be better If I can make the system fit 17" wheels. A light 17" wheel & tire combination  with PBR's is the lightest set up I can find without spending crazy money.</blockquote>
