MT600 brake fluid
What's the brake fluid of choice for those tracking the car? I was about to swap out some old Motul fluid and just wanted to see what people were using.
Also are all compatible with our ABS? Seems the chain store (autozone, pep boys, etc) that sell dot 5 brake fluid for ordinary fluid changes aren't compatible with ABS.

There is no such thing as brake fluid that is incompatible with ABS to my knowledge. There is only one exception and that are the DOT 5 silicone fluids which are not compatible with DOT 3 and DOT 4 glycol based fluids. DOT 5 absolutely cannot be added to a system that contains any traces of DOT 3 or 4.

I use Motul 600 exclusively. Best prices I've found is here: http://www.motodepot.com/accessories...l_service.html.

The Man
Tim, I have used Motul 600 for a few years now while tracking the car, I have a bigger brake upgrade from Pettit and have very little fade after a hard 20 minute session( I also use Hoosier R3S03 tires). I find that I don't need to bleed the brakes but maybe 2 times a season with Motul versus the Synthetic Valvoline I used to use. I am interested in trying a new Brake fluid I saw a couple of months ago in Grasssroots MS mag, but I don't recall the name(its supposed to have a lower affinity for capturing moisture and a slightly higher boiling point)

For the record, I used ATE Super Blue. I run the stock brakes with N-Tech Lapping pads (and Victoracers). My car isn't a dedicated track car so that is the reason I picked Super Blue over Motul.

In general the whole moisture in your brake fluid is a myth.
Dow, who is the worlds largest manufacturer of brake fluid did testing on brand new cars and cars that had been out of service for 2+ years sitting on dealer lots. The result was the cars on dealer lots had less than 0.01% more moisture in the fluid than the brand new fluid. It's just a myth to sell more fluid.

Often times you can spot a car with lots of moisture in the brake fluid when you flush it. If the old fluid comes out sort of "foggy" and with lots of tiny, tiny bubbles that is water, not air.
A normal street car doesn't notice the problem as much because it never gets the brakes hot enough to cause the water in the fluid to boil. You don't notice a problem until the fluid gets hot and the water boils. This makes the fluid compressable and gives a spongy pedal that will appear to have fixed itself when everything cools off.

I know most racers bleed before (and during ) every event. While I think that's overkill in our light cars I do bleed my race car every 3 months. Motul has a reputation as being prone to moisture absorption.

Go with super blue. Most other high temp brake fluids will absorb water over time but the ATE won't become contaminated as quickly. Basically you can track the car all year with this stuff if you only go to a few events.
If your an advanced driver really pushing the limits I would bleed just a bit quarterly
I've only had a pedal go soft once on an FD and I was using fresh AP 600. I was using a wilwood BBK that did not have thermlock pistons and they would boil the fluid about every other session giving me a soft pedal. It's not a good feeling but I still had brakes. What I'm trying to say is the fluid is important and keeping the brakes bled etc....but the most important thing is having good brakes, ducting, and pads to start with.

I personally alternate between ATE Super Blue and Motul 600......that way when you're flushing the system you can tell when the old stuff is all out. I think they're both superb, and plenty good for the normal open track weekend (true pure racing maybe different).
Though I have to say it's fun when you're autocrossing and some uninformed tech inspector thinks you've poured windshield washer fluid in your brake reservoir....

ATE Superblue = blue color

ATE is the brand name (from the Alfred Teves Company, founded 1906).
Manufacturer's current corporate name is Continental Teves AG & Co.

DOT 5.1
Polyglycol based brake fluid, exceeds the highest DOT specs. For use in all systems that require a DOT 3, DOT 4 or DOT 5.1 fluid. The container is filled with nitrogen gas to increase shelf life and eliminate contamination while factory sealed. DO NOT MIX THIS PRODUCT WITH SILICONE BRAKE FLUIDS.
