Is that true if you're running the stock Campy magnesium wheels? I think the lubnuts on original Campys (not clones) are only supposed to be torqued 50-60 ft.lbs.
Regarding improvements to a stock brake system...
Vented rotors for a 66 Mustang are a direct bolt on replacement for the front rotors according to posts to the DT Mail List. This gives you all kinds of options for slotted, cross-drilled, cryo-treated, etc. performance rotors. And, they're inexpensive! The only thing you need to do is press out your metric lugnuts to install on the Mustang rotor, or order a new set of lugnuts from one of the vendors.
For the rear, Larry Stock at Pantera Parts Connection (Reno) sells custom Brembo slotted and/or cross-drilled vented rotors which are a direct replacment for the stock rear rotors. And, they work with your existing stock calipers.
Then, as your budget permits, you could upgrade calipers, booster, flex lines, etc along the way.
Cheers!
