It's probably impossible to warp them by overheat. I drove my 505 Turbo
one time in a Rally so hard that I acheived 100% no brakes whatsoever and
kept going at speed to cool them. Even with that, no warp. I did conclude
that 505 brakes, in spite of their nice 261 size aren't up to fast
driving. Janet Guthrie confirmed that when she mentioned in a letter to me
that the IMSA and Firehawk 505 enduro cars were brake limited.
BUT... you can easily test any rotor by jacking your car up. Pull the
pads, and speed the rotor by hand. Use any fixed objact as a reference,
even a crate on the ground (where are thos enice wood/metal milk crates
these days) and look for run-out. Obviously, this is trickier on a FWD. If
you're gutsy, jack up both wheels in that case and let the engine spin the
FWD.
