The fronts should get the 11" upgrade, its not that big of deal.
The 73mm caliper is an "ok" idea, depending on who you ask. Sure its "better" but bang for the buck, and effort, not really IMOHO.
The rear brakes, drums gotta be converted to disks, mentality is not really true either. I race on my drum brakes for 3 years before I upgraded. Sure, they sucked, but its the fronts that do 70% of the stopping power.
Save your pennies for the M2300K brakes. These have 13" rotors and 11" rotos, and will require 17" wheels, and $$$ These are nice brakes, not as good as Brembos, which are even more!
Biggest short term gain is 11" front rotors. Then Performance Friction "Z" pads from Pep Boys or Autozone for $60. These are better than the typical $30 pads, and have a lifetime warranty (I used once/year). The last thing is VENTING. Yes, get some airducts and aim them at the rotors. This is the single largest gain on stock brakes. A fresh bleed with Ford HD brake fluid, and your set for weekend playing.
