Changed mine before each track day per the owners manual

I am nearly certain the owner's manual (including the high performance guide) does NOT tell you to change the diff oil every track event. After the first two changes (see below), it's based instead on number of track hours. I have to check on the exact number but it's something like 20 hrs.

To be fair, they do tell you to change it at 1500 before the first track event, and then (I think) after the first track event. This makes sense since the first 1500 has debris from manufacturing and run-in, and the first track event is likely to be the first time you really place high demands on the rear diff gears and clutch, so likely more unusual wear.
