I'll probably go with something like this Street or Track 11'' Rear Disk Brake Kit if I add rear disks. Due to budget constraints and the fact I only do autocross and not open track I'll probably adapt a similar factory setup from a crown vic cop car.

I have done the Mustang Steve v6 brakes and I can tell you that all of the components are extremely heavy. I eventually went with the Baer SS+4 system in the front. The system uses 11x1.1" 2-piece rotors, and includes aluminum hubs, etc...everything fit great and was light weight. I have drums in the rear now, but Baer also offers the same system for the rear with an integral drum brake for the e-brake. I've been very happy with this system and it fits inside 15" wheels.

I don't know about Neons, but some cars with this rear brake system actually use the same brake shoes as a non-disk system. Ford Explorers and Honda Odyssey with rear disks have almost every drum part except for wheel cylinders. This must have been an easy way for the manufacturers to upgrade to rear disks and not have to redesign the parking brake. It is heavy.

Don't think I'd want to balance out the bias with (what I assume) will be 11"
front disc and 11" rear disc. 11" rear rotors are big on a vintage Mustang.

not afford much of a "heat sink" when converting kinetic energy into heat energy and dissipating that energy.
Definitely agree. I never tracked my 65 but I gave it some seriously competitive street use. While cold, the Kelsey Hayes calipers and factory rotors stopped much better than one might expect, but I over heated them several times. Some serious fade.

I did the same thing with my 66 GT when the brakes were stock. A 1/8 mile
offramp was not adequate to stop from whatever asinine speed I was going.
So I upgraded to the B302 Trans Am fronts. Problem solved.
