This is what I am using, full time in the car.

Only thing with this fluid is to make sure it is not left open, and to refresh your brake fluid regularly as the fluid is very hygroscopic(adsorbs lots of moisture from the air), which can result is internal rusting on your brake lines and reduced performance from the fluid (wet boiling temperature)
Used at mondello for a full track day and lasted better than the tires, on a dry day with laps times at circa 2:15.
Don't get DOT 5 as that is the one that breaks down the rubber seals, from what I have read.
