A minimum rotor thickness should be cast into the rotor itself...

well, thats what i used to think, but they're been a couple different times, on different cars, that iv seen this not to be true, usualy on stock rotors though (haven't checked any F-body ones though). and i lost my chiltons book.

My 89 rotors do NOT have the min thickness cast in. Quite irritating. I had to look it up in my 91 Helms manual. Can't remember off the top of my head what it was though.
