I'm going to be putting on a stoptech kit and figured I should probably replace the fluid while I'm at it. What is the best high performance fluid for our cars?
You don't need "high performance" brake fluid just because you change your brakes. You need better fluid when you change the driving conditions that dictates normal DOT4 is no longer adequate.

true that!!! Will told me to get the racing fluid... because... stopping a car with my kind of power requires the racing motul, so under long braking.. the oil doesnt brake down.
If you want highest wet boiling point - Castrol SRF
If you want it to match the color of your car - ATE Super Blue
Motul RBF is a good choice since its easy to find at motorcycle shops, but its wet boiling point is almost 100F lower than Castrol SRF. Dry boiling points are similar so if you change your brake fluid each time before going out on the track there wont be much difference. ATE super blue is half the price of Motul though and its boiling points are 30-50F lower than Motul so a good value to use on the street or if you dont heat up the brakes too much on the track.
Thank you for the info! I figure regularly fluid is fine but I figured while I'm there I could step it up some. What's the difference between dry and wet?
Although I'm not the expert on braking and brake fluid, I would speculate that an occasional aggressive braking maneuver still does not require any fluid upgrade. If you do it a lot, or a lot of times right in a row, then yes, upgrade to avoid squishy pedal syndrome.
Dave - you are correct. Occasional heavy braking from high speeds, or moderately paced DE sessions should not be a problem. When you pick up track pace and get things hotter for longer, with little cooling time between applications, it is THEN that fluid becomes an overwhelming safety consideration.
I tried Motul 600 and it didnt work for me. I tried AP 550 and it was much better, but not perfect. I moved up to AP 600 and never again had problems regardless of pad selection, or track length, or configuration. It is half the price of SRF.
SRF is probably the best I've seen, but $$$$!
Like others have said, it really depends on what you're doing and how hard you're pushing it. SRF would be a total waste of money if you're not really pushing it on the track.
Even tracking it, RBF600 is probably going to be plenty good for you, and doesn't coast nearly as much as the SRF. I do a decent flush after each track weekend, and a complete flush every other weekend, so it works fine for me.
The only brake problem I've had was trying to make 1 set of pads last 2 weekends. Once the pads get down 50% of so, you definitely start getting more brake heat than before. Now I've got a garage full of half worn brake pads. lol
Since they're so easy to change, I'm just going to take them all with me next time and swap them in and out at the track. I should have more than enough to make it through a weekend without having to buy a whole new set.
DOT4 will stop the car just fine for street use. So I guess knowing my brakes will work is worth $2.95 per pint at AutoZone.
For street maybe. Since we are even talking about upgrading brake fluid I don't think OP is asking for opinions for street use though.
Having your brake pedal go straight to the floor while doing 170mph at Daytona will change your mind very quickly on what you want in there for any kinda of spirited driving

Won't argue that whatsoever but I think the OP is mainly high performance street as opposed to super speedway track. Probably time for the OP to chime in on intended use of his car to clarify since that is kinda important.

Well I'm doing a brake upgrade and the fluid I've had has been there as long as I've owned it and figured I should change it to a better quality fluid. My driving style will consist if hard street use. Drag strip runs and I do plan on tracking the car. It will not be a all out track car. But will see the track

Take it from a avid road racer with the Stoptech big brake system in this Gen 2, Castrol SRF is the absolute best period the end. No fade and you don't need to bleed them as much as the others.
