Flush it all with Motul 660, its good high temp stuff. If you want to pay more get some Castrol SRF.

The advantages to SRF is you can change it a little less often if you’re not boiling it too badly, and you let the brake fluid sit in the car for months. With 4-pot base brakes bring extra fluid to the track in case you want to bleed some between sessions (if the brakes get spongey due to air in the lines). Even with the Brembo 6 pistons, I’ll often need to bleed some at the end of the first day of a two day event. Our cars are heavy AF.

Second here for SRF. If you're going to go through the effort of bleeding andfflushing regularly, Motul 600 is great.

SRF > RBF660
RBF660 > RBF600 by a very small amount when 'fresh' (but may need more frequent attention to stay that way)

depends on your definition of “best”. Dry boiling points are similar between SRF and RBF600/660. 660 is marginally better than 600 but costs more. SRF had better “wet” boiling point than most others (read wet as old fluid), but its expensive. RBF600 will get you through the day just as easily as the others if its fresh.

I'm gonna respectfully change the topic here a bit, but I'm wondering why exactly you are looking for specifically a brake fluid change?

Are you finding that you're outdriving the brakes? Have you had trouble with boiling the stock fluid? What other mods do you have on the car and most specifically brake pads and rotors?

I use ATE type 200 brake fluid in my base GT. I've heard great things about all the fluids recommended so far, especially the SRF

I ran the ATE200 fluid while I had either HPS or HP+ pads on the car (street driving with only one cautious track day). When I stepped up to Carbotech track pads, I went to RBF600. Since then, I've heard more than once that higher-mu pads can cause higher caliper and fluid temperatures.

2-3L for a full flush. I try to do it in 2L but its hard to tell when to stop on each caliper when its all about the same color.

I've used stock rotors and both the Track day pads and G-loc R12's. Was able to fade the track day pads as I got faster; hence the R12's. Just curious, how many track events do you have under your belt and what tracks?
