Just wondering where does the 0,60 figure come from?
Is it something Ford said.
Or is it just a safe number that all cars have to use?

Don't know much about drums, but disc's you use the number the manufacturer say.
And its usually "stamped" on the disc.
If you have an opportunity, take a look at a '40 drum that has been turned past .060. I have some that, according to my drum mic, are .090, .100, one is even .120. These came off old brakes systems.

Even at .090, the metal band is visibly thinner. Why does that matter? A thin drum will heat up much quicker and starts to distort causing brake fade.

My thoughts are, cut corners somewhere else. Brakes are crucial for you and everyone else on the road with you.

Interesting note, the ribs casts into Lincoln and '42-'48 drums are to strengthen the drum outer "band" and to help aid in cooling like at air cooled motor.
