There is a lot of talk about warped rotors.
If you have ever checked the runout on a set of rotors, please list your findings here.

I have 50 000 miles on my rotors, after they were turned! I don't know how many were on them when I had them turned.

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.
