Tremec recommends Pennzoil Synchromesh (since their fluid is no longer available). I've been running the Pennzoil Synchromesh for several track events now. It's maybe not quite as good as the Tremec formula, but it's pretty darn close.
If you currently run Royal Purple, I'd encourage you to try some alternatives. I bet you don't go back.

Well I’ll be damned. What pace/run group are you at most track days?
