I don't see an issue with removing a shim so long as its not leaking oil.

Will do, its weird as I have only had this problem on the new 16 diffs, the tiny ones haha. I have heard people have had to sand down the housing a little bit, but ideally i'd have it much simpler and just run with a smaller shim. And after running at 6-7 meetings it hasn't leaked a bit, just very tail-endy, annoying when you feel really fast then have a small spin because the cars doing weird things and clipping a corner haha. Thanks for the help though, will try a different o-ring as you said, if not i'll have to rely on the shim fix.
