i am also about to upgrade my front brakes but am confused on how different color calipers can make up for over $100 difference..... the cobra/mach/bullitt calipers are all the same correct? .... i see buyfordracing.com has the mach kit for $360 but if i wanted to get red calipers say, the bullitts.... i would have to pay $100 + more for the same thing?? am i missing something?
