BIG front disks (13"+)

Thanks everyone for the quick replies. It looks like the biggest issue is going to be the hubs..ill do a bit of research on the diameter of the stock spindles vs mustang II vs...whatever and see what i can find. In the accident i was just in where someone rearended me at 40+ (while i was at 0) i had the stock 11.25" fronts locked up-i knnow bigger brakes wouldnt have helped any for the car in front of me. But i would like to have bigger brakes for the aforementioned benefits, and braking from high speeds/extended use
