In regards to the overfill, It was a very reputable shop that did the work on the diff . I don't believe so (Sometimes **** happens)

It was probably 105 air temperature 125 degrees at track temperature along with my hot *** exhaust and me driving the crap out of the car. I posted a video of that track day. May be someone can enlighten me.

Anyway, I pulled off track and drove an hour and a half on a Saturday, they drained the fluid, added a 3 foot breather tube in case I cooked the oil, put in a different fluid and it seemed to work. Now that I have the time, I want to get all of my cooling issues in order so that I don't have to worry so much about the warmer days.

Also, from what I can remember, there are quite a few people that have boiled over their fluid while racing and had the same problem. The worst is the cleanup and even after driving it, you have to wait about 2 months for the stuff to burn off.
