Be ready to part with a LOT of money for it. I'd try some Motul or Ate first to see if that solves your problem for a fraction of the cost.

I've used Motul 600 and ATE SuperBlue/Typ200 and haven't had issues with either. This was in my '82 RX-7 racecar and my '89 Caprice street car.

Re: What brake fluid does not boil faster???? (chad)
Yeah chad, I agree AP 551 sucks.....sat. practice I boiled it after 4 laps. I have boiled AP 551 more times than I like to admit. Thanks again for the Motul 600....didn't have brake problems sat. or sun. That stuff is great. I will be switching my ITA car over to that also for next SCCA race. Tell Dave I will send him some dough for those bottles.

Re: What brake fluid does not boil faster???? (jeimport)
So, here is a different point of view.
Brake fluid itself rerely boils. Its the water it has absorbed that typically boils and causes the soft pedal.
In the honda and in my Talon (a quite heavy carat over 3000lbs!) I used regular DOT 3/4/5. I would rather the brakes start to fade ( I can pump them up if I have to) then find the next weakest point in the system which will be the o ring on the caliper piston. When it goes you have NO brakes.
So, just make sure your fluid is REALLY fresh and you should have little problem.

The only fluid I've never had a problem with is Motul 600. Years ago I was chasing a brake fade problem, and was using Ford HD. Switched to Motul at Carbotech's reccomendation.
I have *never* had anything but good things to say about it and won't use anything else. It's a little pricey...but far cheaper than running out of brakes and balling up your car.

The higher the boiling point (boiling temperature), the harder the fluid is to boil.
Dry boiling point is more meaningful for brake fluid that is reasonably fresh - which is (or, at least, should be) true for cars driven on the track. Wet boiling point is important if you plan to leave the brake fluid in the car for a long time without flushing - not a good idea for track use.
Here are the dry and wet boiling points for many of the most popular brake fluids:
ARRANGED BY DRY BOILING POINT:
DRY:401F -- WET:284F --- DOT3 MINIMUM
DRY:446F -- WET:311F --- DOT4 MINIMUM
DRY:500F -- WET:356F --- DOT5 MINIMUM
DRY:502F -- WET:343F --- VALVOLINE SYNPOWER
DRY:509F -- WET:365F --- MOTUL 5.1
DRY:527F -- WET:302F --- AP RACING 551
DRY:536F -- WET:392F --- ATE SUPERBLUE/TYP200
DRY:590F -- WET:410F --- AP RACING 600
DRY:590F -- WET:518F --- CASTROL SRF
DRY:593F -- WET:420F --- MOTUL RBF600
DRY:610F -- WET:421F --- NEO-SYNTHETIC SUPER DOT 610
DRY:620F -- WET:425F --- COBALT SUPER XRF
ARRANGED BY WET BOILING POINT:
DRY:401F -- WET:284F --- DOT3 MINIMUM
DRY:527F -- WET:302F --- AP RACING 551
DRY:446F -- WET:311F --- DOT4 MINIMUM
DRY:502F -- WET:343F --- VALVOLINE SYNPOWER
DRY:500F -- WET:356F --- DOT5 MINIMUM
DRY:509F -- WET:365F --- MOTUL 5.1
DRY:536F -- WET:392F --- ATE SUPERBLUE/TYP200
DRY:590F -- WET:410F --- AP RACING 600
DRY:593F -- WET:420F --- MOTUL RBF600
DRY:610F -- WET:421F --- NEO-SYNTHETIC SUPER DOT 610
DRY:620F -- WET:425F --- COBALT SUPER XRF
DRY:590F -- WET:518F --- CASTROL SRF
As you can see, Cobalt Super XRF has really high boiling points, and at $12 for a 12-ounce can, the price is quite reasonable. You can order it from Andie at Cobalt Friction, the brake god who sells lots of great brake products at great prices.
