ATE SL6 brake fluid

[lavmugen]

I'm going to do my first HPDE in a couple of weeks. My mechanic recommend that I at least get new brake fluids for a bare minimum.

He suggested ATE SL.6 brake fluid for me (I only plan to do 1~2 HPDE/Track day and 4~5 autocross per year).

Has anyone had experience with this fluid?

I -ed and found nothing =(

Just get ATE Super Blue DOT 4 fluid. It's much better than stock (in terms of boiling point), and it comes in two colors which helps when changing fluid. You can buy it at many online retailers, including the Tire Rack.

You won't get to the point of boiling this fluid until you have significantly more experience at the track.

Enjoy.

what Ruffan said.

anyone with experience on the SL.6?

it's supposely designed to work better with electronic traction control systems

That sounds ridiculous.

Super Blue has a higher boiling point which is what is of main concern at the track. When fluid gets hot it can boil, introducing air bubbles into the system. When you have air in the system you will get a spongy pedal as the air compresses and doesn't provide the pressure needed to squeeze the brakes. I would bet that the super blue would hold up better to the heat cycles of track driving.

i dont know anymore

i originally wanted to go with Motul RBF600, but my mechanic said it would be overkill for the amount of tracking time i will see. And Motul is more expensive.

(Resurrecting an old thread for anyone googling ATE SL.6...)

For street use, BMW is recommending a low viscosity fluid, I just picked some up from Turner Motorsports. From their site:

"The Ate SL6 fluid is a low viscosity formula for modern ABS and DSC systems. BMW recommends low viscosity brake fluid for all chassis beginning with the E60 5-series. Low viscosity (LV) is a thinner fluid that works better than a normal fluid in the small channels and passageways in the ABS/DSC pump. Using the heavier fluid will result in a delayed response to ABS and DSC activation and a spongy feel in the brake pedal (only during ABS stops). Ate SL.6 falls just short of DOT5 specs so is classified as a DOT4. It can be mixed with other DOT4 or DOT5.1 fluid. For track use, a heavier high performance brake fluid such as Ate Typ 200 or Motul RBF600 or RBF660 is recommended because of their higher boiling point and because the thicker fluid will thin out at track temps. But for street use we recommend switching back to a LV fluid, especially in colder climates."

Yeah. It works fine.

They all will feel the same up until you cook the fluid and get air in the line. SL6 resists boiling better than stock and is fine for what you're planning on doing and it's pretty high value. Check out the attached chart and sort by price/oz.

If you do end up needing something really aggressive for a track car, Torque 700 is where it's at.

i second going with ATE Typ 200. it no longer comes in Super Blue; the Feds dictated the end of the blue dye as they thought people could confuse brake fluid with other blue fluids (coolant, wiper fluid). i know its silly, but nonetheless . . .

It comes in blue in some countries?

I switch between the two (blue and amber), if it was an i3 I might use the low viscosity fluid.
