Just curious, what brake fluid are most people using? Please state what type of driving you do.

 

I alternate between ATE Super Blue and ATE 200 for track use.

 

Motul RBF660. Autocross, occasional track, spirited street driving.

 

Motul RBF600 on both my Evo IX and X. Use on street and on track. Really wanna try Castrol SRF next track day

 

Amsoil DOT4 Auto-X and daily duties

 

Unless something changed the ATE blue is not legal in the US

Its what I run as well. Will convert to the standard ATE next flush

 

if you track a lot, catrol SRF is the way to go. it has the highest wet boiling point of 518°F

 

YOLO

It is illegal because... wait for it... it's blue!

When the law changed, I picked up a case.

 

Amsoil DOT4

 

Ford--, 600* boiling point , less than 10.00. If i remember correctly. DD and track every once in a while,

 

Motul RBF660

 

This is true, this is probably the best fluid you can use in general, SRF is racing fluid.
I've done a lot of research recently with fluids for business reasons.

Castrol SRF (if you can afford it)
Motul RBF660 (cheaper solution)
Motul RBF600 (still very good)

Are all very very excellent fluids.

 

SRF cost more, but pennies considering all the other consumable cost associated with tracking regularly. brakes is one of the most important thing on your car. and you don't have to flush as often with SRF, so it'll cost the same as other stuff in the long run.

 

My brother-in-law runs the cheap Castrol DOT 5 stuff in his E36 endurance car and changes it after every race without issue. Says it's still cheaper than running the SRF.

 

DOT 5 is silicone-based fluid thats not compatible with stock braking system.
