You the man Tom.
I'll call them next week, but i won't be using the oil untill summer hits when i'll upgrade my gears and clutch.

Hey, no problem.....just a small way to show the appreciation for all the support the forum has given our team!!
The topic of brake fluids is enough for another whole thread....but here goes...
We have tried all the super high temp fluids and they do work great. They provide superior high boiling point capabilities when you need it. One of the tradeoffs with most of the very high boiling point brake fluids is that they are very hydrophilic or they love to absorb water (or moisture in the form of humidity). So soon after you fill your system with this type of brake fluid it starts the absorption process. After a short time the moisture degrades the brake fluids boiling point to significantly less than the initial advertised boiling point and many times less than the boiling point of regular DOT3.
So the concern here is that with these fluids you need to change your systems entire fluid frequently to maintain the high boiling point they are designed for. If you really don't need the high boiling point you may be waisting your money....
If you want to use one of these for a track day, etc., then it s a very good idea to flush your system with new fluid afterwards!

i was thinking of getting another thread starting but i'd seem like i'm taking over your section so i just threw the Q here.
Thnx for clarifying those facts, i had that impression but wasn't sure in details.
Now can you give some name or boiling point or something i can work with to choose something right for MSP , I figured out that I best change the brake fluid once in 1-1.5 yr which isn't much but isn't that long either .
would motul DOT 5.1 be better then Motul racing fluid 600 ???
or ATE is something to consider ??
Give me something i can work as to choose the right one , thnx
It really depends on what type of driving you intend to do....
If you will only be using the MSP for normal street driving with some added "fun" street sessions to exercise the car you shouldn't be overtaxing the brake system too far and normal Dot3 or Dot 4 fluid should be fine.
If you will be tracking the car then it depends on your driving (or braking) style and whether you find that you are getting true pedal fade from boiling the fluid. If so then move up to the next higher boiling point fluid and see if that takes care of the problem.
Beleive it or not we only use a 570 degree boiling point fluid in the race car because we determined that the long pedal we were getting wasn't from fluid boil but rather due to "pad knock back" from rotor warp under heat.....again another whole thread worth of discussions.....
BTW, don't worry about starting various threads with questions....this is exactly what I intended this forum to be about!!
