Here are the link's I used to swap over to 03 Mach 1 disk brakes front and rear. I used 95 spindles, 95 cobra brake booster and mastercylinder, ford racing proportion plug, braided steel brake lines, stock 98 mustang gt axles, and a summit adjustable rear proportion valve. The brake pedal is rock hard and the car stops soo fast with next to no pedal effort!!
