you really dont have to get the best fluid for a street driven car. The best fluid only works better because it can tolerate the extreme heat created during Track time..

If you must use the best get ATE superblue or Motul brake fluids.. Race cars usually runs those.

Valvoline Synthetic Brake Fluid is great for everyone... the one sold in silver/grey bottle.

Use only DOT 4 fluid, and not DOT 5 which is not compatible.

Ate Super Blue (blue in colour) alternated with Ate Typ 200 (gold in colour) is a good approach. Easy to tell when one is fully flushed out by contrast with the other. Not expensive either - about $US 10/liter, maybe cheaper if you shop carefully, etc.

Enjoy!

ATE racing Blue is not a DOT approved fluid. I have run it without issue. Type 200 is about the best standard replacement.

ATE blue and TYP 200 are the same thing but a different color.

They exceed the DOT4 classification by quite a bit when it comes to wet boiling point, and have high dry boiling points.

Mutol RBF600 is 25F higher than ATE on the wet temp and about 60 higher on the dry, but at 1.5 times the cost.

Castrol SRF is VERY expensive, and you wont buy it but it does have a wet boiling point 100 degrees above the Mutol!

if you race the car often, and are going to replace the ENTIRE brake system (even the steel lines) then thats the fluid for you.... at the cost of about $120 to bleed the system.

Racers: SRF
Trackers: RBF600
Everyone else : Superblue/TYP200

Valvoline has a wet point 50F below Superblue and 75F below RBF600 by the way!!! and its dry point is 33F below Superblue.

and that dealer is a lying sack of crap, stay away.

also, Superblue should be DOT approved, because it meets the DOT4 and 5.1 temp, fluidity, and compressibility specs.

The dot 4 brake fluid at the stealer is 5 bucks. im not sure whats actually int he bottle, but i always feel better about using things with a bmw logo on my bmw.

I work for a bimmer retailer sorry to hear that....talk about pressure sales! Just use a brand name dot4 fluid like some of the brands reccommended by our fellow board members....thats what I do for my 525
