Does anyone know what brake fluid the 992 GT3 RS comes with? I'm trying to determine whether I need to put new brake fluid in for a track event at COTA soon.
(I would use Motul RBF 660 or Castrol SRF... input here welcome too).

I don’t have specific knowledge about the new RS, but all previous GT cars have come with the Porsche-branded sauce that seems to be relabeled Ate fluid (garden variety DOT4). Better fluid might be a good idea if you’re gonna exercise the brakes hard.

I would definitely change brake fluid for any car going to COTA. The dealer does track days there every quarter or so. All cars with the Porsche OEM brake fluid develop fade to some extent.

SRF and don’t think about it again (of course flush as appropriate).
