Super Blue = No boiling brake fluid
I use this stuff in my auto-x car and my daily driver. It works fantastic for preventing boiling when I am auto-xing, and it has a long life, so thats a win for my DD. 2000 Honda Civic DX auto-x and 2003 Pontiac Vibe DD. A little pricy, but it gets the job done.

Super Blue Dot 4 Brake fluid
Excellent transaction, easy to do business with, fast shipping. Overall Excellent.

Excellent & Expeditious Service
I used ATE Super Blue Racing Brake Fluid Dot 4 for 9 years on my 911 Carrera 4. I feel it to be most superior product for high performance vehicles. The seller I purchased it from was most accomodating and would definitely purchase again this and other products they may offer.

If you run your car on the track, you will need this product
Most brake fluids are DOT 3 - good enough for the street and normal driving (if there is such a thing). If, however, you run your car at high speed events like your Porsche, BMW, Ferrari, etc., club track days, DOT 3 just won't cut it.

DOT 4 grade brake fluid has a higher boiling point so it helps prevent bubbles forming in the caliper at high disc brake temperatires. When you're really hammering the brakes (braking from triple digit speeds lap after lap) the heat in the disc and caliper can get so high that it can cause the fluid to boil and at best, give a spongy brake pedal feel. At worst, your brakes can go away completely (that's change your shorts time!). ATE makes a good quality product. They make brake components (e.g., calipers) so they really know what works.

I (and many of my track-junkie friends) have been using this fluid with good luck for years in our German cars. Also important, it has never damaged the seals (I am told that it can happen with some products). Change your brake fluid at least once a year and bleed it before every track event for maximum safety.

NOTE: ATE makes a blue fluid and a gold fluid (identical except for color) so that you can see when the fresh fluid reaches the caliper when you flush your brake system.
