DOT 4 Brake fluid
Any of you track rats switched to DOT4 fluid? Is it necessary in your opinion? Do you have problems prior and/or did you notice an increase in longevity in longer sessions?

Yes, switched to Castrol SRF.
Necessary in heavy cars like ours.

If you are tracking, it is critical that you switch. Expensive brake fluid will be the cheapest insurance you'll ever buy.
especially if you have a ZL1 1LE. Castrol SRF, Brembo HTC64T or Endless RF-650. Read the track day prep in the owner's manual.

Ditto. 100% required for track driving. Castrol SRF and Brembo HTC64T are two options I've used previously and both do well.

1.5L but get 2L to be on the safe side.

BREMBO HTC64T OR CASTROL SRF!!!! My local dealership switches mine out for me and only needs 1 Liter to make that happen. Like someone has already said.....it is the cheapest track insurance you will ever buy.

Motul 660 did not work for me. I had excessive reservoir "sweating" which may have been actual boil-over.
More importantly, my pedal became very spongy at times. Switching to Brembo HTC64 eliminated both spongy pedal and sweating, I know Motul makes high quality stuff but I would not use 660 again... Castrol or Brembo only IMO. |
