Very true, never though about the mud and rocks.

I guess I was looking into those because the rotors (Stock) that I have on
there now didn't seem to last too long, but I guess they did.

Thanks

Not racing the jeep anytime soon.

Just though I would've wanted them because these rotors seemed to warp
rather quickly between having them cut and now.

Stop running the lightweight factory composite rotors and go to a good
quality solid cast rotor, you won't have any more warping. Be sure too to
hand-torque all the lugnuts evenly (all at the same tightness, take your
pick between 85 and 110 ft-lbs.) which may help reduce rotor warping too.
