RE: How much do they warp? Proof requested!
At 86,000 miles, I put pads on my '93 and checked both front rotors.
Both sides checked at 0.001 inches runout. I believe 0.003 inches is the limit per the manual. Passenger side thickness 0.984 inches, drivers side at 0.995 inches, with minimum specification at 0.974 inches.
I have 105,xxx miles now with no brake issues, but was warned at last inspection the rear brakes would be due soon.
