"Picture this..... You're at Mazda Raceway/Laguna Seca, you've come out of the Corkscrew, managing to pick up a little speed and get the inside line, you touch the brakes for Turn 9, Rainey Curve, brakes feel great; solid pedal with a firm feel, back on the throttle at the apex, heading toward Turn 10, again on the brakes, a little more than for Turn 9, into the apex and down the short chute to Turn 11. Hard on the brakes coming into Turn 11, trail-braking down to the apex and back hard on the throttle for the long front straight run down into the Andretti Hairpin for another lap..."

How many people are interested in a super high temp brake fluid?

683.2° F (361.8° C) Dry Boiling Point
439° F (226.1° C) Wet Boiling Point

That is higher than AP PRF!!!
607 F dry, 399 F wet boiling point

Higger than Motul 600!!!
594 F dry, 421 F wet boiling point

Higher than Brembo LCF600!!!
601 F dry, 399 F wet boiling point

You brake before T9? Chicken! In my case the piston boots melt before Motul 600 yields. I guess a little more boiling point headroom couldn't hurt - especially if you have aftermarket brakes.

I am WOT between 8 and 9, tell me if I should at least slow it down a bit for 9 or not!

I'm interested. Depending on price of course.

I tried Castrol SRF on my Audi's before..and it was overkill. I have never boiled over the Motul 600 before..its fine for me. It might be better if you keep going to Buttonwillow/Willow Springs/Streets/Cal Speedway. :-)

What happens if you put that brake fluid in stock brakes? Anything bad could happen?

Prospeed RS683 Xtreme Performance Brake Fluid

What does your brake pedal feel like?
Isnt it really about control? Why do you see track guys using the blue stuff (or the other cheap brake fluids) come in after a 20 minute session and bleed the brakes? Because they demand the best pedal feel and control from their brakes in the every session. In other words, unless they bleed the system after each run they don't trust their brake fluid to give them the control and pedal feel they want.

Are you getting all the control and performance from your brake system? New Prospeed RS683 is the newest and highest performing brake fluid available today.
