IMO a thermal switch should be used with those 2 type if you want to be on the safe side
I went with the 40-527 and ofcourse that thermal switch even if its not required.

Edit, what a second, now the PDF file on all of them has changed! Wtf! Seems they redid the PDF file because everything was wrong, I hope. Now I guess you're right Megan. Weights are switched too.

524 is intermittent and 5.5lbs 1-2hr, 15 min cool down
525 is continuous and 3.5lbs 1000hr continuous

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.
