BIG front disks (13"+)

Unless your running a large front racing compound tire like a viper 295/18/30 there is no advantage other than heat disapation which you would only notice on a track vs the street.
I was hoping to learn something here because I could be wrong?
Nobody will debate me with thier hypothesis so maybe you guy's dont know either? (braking advantage in going from a 12 inch rotor to a 13 inch rotor)
I get going to the 13 inch rotors for the COOL FACTOR!!!! Looks COOL

But you have a street car and from what you wrote below you had a heat disapation problem. If you were boiling Willwood fluid you were getting the brakes hot.

There are three types of Willwood fluid: http://www.wilwood.com/BrakeFluid/BrakeFluid.aspx This is the higher rated stuff: EXP600 PLUS Brake Fluid
Dry Boiling Point: 626 °F Wet Boiling Point: 417 °F

I looked into the ARE viper kit also. After alot searching it was the best kit for the money I could find. If you do a search you can find the Multi piston viper calipers on E-bay. Lot cheaper than ARE's. I think on Ebay you could get them packed(all the stuff) for $300 bucks a pair.
I have street wilwoods on the front of my Dart and have Brake fluid boiling issues with the single piston caliper and the smaller disks.I was using Wilwoods HP brake fliud which I found from the spec to be nothing more than reg brake fliud in a Fancy container. Same specs as conventional Autozone brake fluid at twice the price?
Converted to ATE Blue Brake fliud with a wet boiling point 380F -570F dry. Made a BIG DIFFERANCE
