yep, high temp brake fluids. BMW synthetic engine oil is good enough. Keep in mind that both of these are recommended to be flushed every 2-4 days of DE. Expect 270+ for the oil temp if you're pushing hard with a tune; this is still normal and shouldn't trigger any limp if all else is well.
I've done about 15 days this year with all stock hardware and stg 1 tune, but had no mechanical issue except brakes. For some reason, I simply could not get rid of brake jutter when they got heated up. I would highly recommend PFC pads (either 01, 06, or 08); don't get anything else for the track.
what made you get rid of it?
