Well, I'd put my vote with the locktab (first choice) and Locktite
(second choice.) I wouldn't trust rust in the short term. And I'd
use that torque wrench! I don't know anyone who has taken off
calipers often enough to have streched out those special (guessing
Grade 8) bolts, but I suspect that if you really got
over-enthusiastic with a cheater bar, you could.
The problem with lock washers is that you can't get as accurate a
torque value as you can with a flat washer and oiled threads. The
other trouble with spring-type lock washers is that they lose some
"spring" over time, and are little better than flat washers. I've
taken off a number on my car that were absolutely useless.
