You can use either. Dot 4 is higher performance. Just don't use Dot 5 thats all....

I know you didn't ask for a brand or anything but I like the Valoline Sypower stuff. Some people like Mutol or ATF Blue but htey are pricy and the Sypower stuff is at every Autozone for $5. It is considered a Dot 4. The difference is boiling temp. 3 less than 4 less than 5 ect. Most dot 5 are silicone and you don't want that your not that hardcore.
A good change of fluid and pads will work wonders for the WRX it did mine.

When would you want to use a DOT 5 fluid. Would that be in a hard braking race inviroment? Or not at all?

Race cars & heavy equipment very high temp brake temps. With the development of better Dot 4 fluid the need for 5 has become less and less.

Dot 5 is generally silicone based - the only people who really use it are those who have show cars (it won't damage paint like a normal brake fluid, but it's also immiscible with water, so the water tends to pool, then form steam when the brakes heat up, resulting in a very mushy pedal and decreased brake performance) - the dot 5.1 oils are not silicone based, so you can use them.

essentially, the higher the dot rating, the higher the wet and dry boiling points.

what DOT rating fluid comes in the wrx from the factory? 3? Is it bad to mix DOT 3 with DOT 4? Would a big brake kit benefit more from DOT 4 fluid or DOT3?

Ted,
you're going to use DOT4. either ATE Super Blue or Motul RBF600 is what i'd go with. ATE has a lower boiling point, but with the stoptechs you bought, that shouldn't be much of an issue. i've got a spare can of ATE in my garage.

Go to your Ford dealer and get Ford HD brake fluid. Boiling temp is very close to Super Blue. Price is much cheaper. For the street is doesn't matter much and a generic dot 4 from Wal*Mart is fine. For the track, Motul is fairly cheap and available everywhere. I use wilwood exp600 which has a boiling point 32 degrees higher than Motul. I'm running a racecar, however....so $20 a 1/2 liter is not a big % of my budget.

Any of the above I like the Valoline Sypower stuff it's cheap and easy to find. You don't need to go all out and try to get some hard to find brake fluid. If you are boiling the Sypower stuff you have other issues.
