IMO, there is no need for concern. I also went a few times above 5000RPM during break-in. This engines revs up so easily...

My point was that if one wants to drive the car hard right out of the bag, it would be preferable to have the right oil in the engine and diff. It is my understanding that the break-in oils in both the engine and diff are not designed for maximum performance but rather to optimize the break-in.

So the ones that beat the sh!t out of the car with break-in oil have issues? Most likely not. But I prefer being on the safe side for these kind of things .
