Swap to a 2008+ front axle. Rotors calipers and pads are all bigger. Plus, some of the other components are improved too. I did it to my van. Take off axles are $400 from quadvan then you just buy a new sway bar with links. It's cheper than a ball joint job (and you get new better ones anyways. )
PS skip the hawk pads and slotted rotors. Tried that route. The newer Ford stuff is way better. And for the rears try Napa extreme duty pads. They have the shortest stopping distances of all the major aftermarket pads and better than stock.
