Any quality DOT4 is a good call. ATE TYP 200 is my personal go-to fluid and what I have in my Z51, but Autozone carries Pentosin and Bosch which are both excellent fluids and readily available locally. Even a basic Prestone DOT4 has pretty good boiling points which is what I have in my DD.

RBF 600 or 660.

Castrol SRF>RBF660>RBF600>ATE200>all other DOT4
More important than what fluid is used is that your fluid is fresh. IF you are pushing the car hard and experienced on slicks, then you at the very least want rbf660 and would be best of with srf, it’s not cheap though

Not all DOT4 Fluids are the same and some DOT3 Fluids like Ford's brake fluid have better dry boiling point specs (500 degrees) than some DOT4 fluids.
Castrol may not be the best fluid for all Drivers. It has a high wet boiling point but it doesn't have the highest dry boiling point. If you want to settle on a 519 degree wet boiling point and basically getting away without bleeding fluid between events then Castrol SRF is probably for you. However, if you want the highest boiling point when you are out on track then maybe you should focus on dry boiling point since there are fluids that have 25 to 75 degree higher dry boiling points.
Check this web site for a Brake Fluid Comparison Chart:

I copied the chart and made it into a PDF file and it is attached to this post.
I also used Excel to Sort the Chart two different ways and generated a PDF file ranking the fluid by dry boiling point and another file ranking them by low boiling point.

Thank you for the information. This will be my second track event in the Z06. I do run cup tires. I am a rookie at this for sure. Unfortunately at the first track event I did run the car hard enough to get the wonderful over heat and reduced power warning. Hope it is better this time as the temp should be cooler.

Completly agree with your scale. I run SRF and would not run anything else available. It seems to heat cycle better as well with track use. I had to swap RBF more far more frequently, about every three weekends on the long end. While SRF appears to be way more expensive, note that it’s sold in a 1L bottle while others are 500mL, so it’s not as bad as you think. And when you can run more then twice the cycles, it’s actually economical if you value your time.

I’ve used them all over the years. I’d never use the ATE fluid; it’s just not robust enough for a car as fast as ours on the track. Motul make a great fluid, but I only use Castrol SRF. It’s not that expensive when you realize that SRF comes in a 1 litre bottle instead of 1/2 litre and will not need to be bled so often.
