Exactly what I asked for

I can understand on a car that is very old or has a crazy amount of mileage on it and has never been done, but I think for a car that is newer and can be taken care of properly its whole life, it is a good idea. Newer vehicles, with all their computers and sensors, also have stricter tolerances than older cars. Again, I do not have the ultra old car, or been driving for 40+ years, but I have been around a car or two in my time, and worked at a few dealerships

I also race my cars from time to time, and that makes a big difference, so if there is spirited driving involved, as with the OP and his SRT-6, I would highly recommend changing the diff after what I pulled out of mine at 50K.
