Can you swap to 13" cobra front brakes while keeping the gt/v6 rear disc brakes? Setup consists of 99+ pbr fronts with a 93 Cobra mc/booster, nrc rear caliper brackets with fox 31 spline axles, all MM steel braided lines front & rear and a ford adjustable prob valve.
It is if you use them hard, otherwise any difference you feel can probably be chalked up to leverage. I wouldn't expect it to shorten your braking distances except from very high speeds or the 10th hard stop on the street.
