Just a short addition to Lance's post. The late SVT's and most 99 and up Cougars have the 278mm front rotors with the same calipers and pads that you now have. I have driven cars with both braking systems and find very little difference in braking ability. If it is good enough for the late SVT it must not be all bad. I believe that the bigger calipers and pads are a little bit better, but as close as they are to each other, it is hardly cost effective to swap to the big calipers too.
