I've said it before, have to say it again. You'll cook the diff fluid. Just driving it reaches 194*. Doesn't matter what you run. I recommend a diff cooler also if you have a sport model. I wouldn't want the OEM LSD to work and not work when you least expect it. Like ice mode it can scare the **** out of you. But it does depend on the tracks layout and your ability to drive fast. If you don't buy one I'd replace the fluid ASAP after the event since it will be cooked. You wouldn't drive on engine oil if it saw 300 degrees or so, so why do it with diff fluid.
