I race with Pentosin Super Dot 4, (just over 500 dry boiling point) in the ‘88 with J55 calipers and have never cooked the brakes even with slicks. I’m also running DRM stainless caliper pistons and have brake cooling duct hoses. I threshold brake and run 30 min sessions. It’s very reasonably priced and what I use in my Z. On the ‘96 race car (WC GT), I run Amsoil Dominator brake fluid (410 wet/ 580 dry) with Coleman calipers up front with cooling ducts and J55s on the rear (threshold brake at much higher speeds). With street tires, I’d think Super Dot 4 would be more than adequate for a track day. That said, I always flush fluid before every event. If you run HPDEs and want to sleep well, I’m sure Motul, Redline or Wilwood 600 won’t let you down. Still, Amsoil Dominator has one of the best wet boiling points of 410 if you want to fill and forget for a year.
