Which are highly hygroscopic then?
Well duh, glycol-based fluids, which your Motul one is.
DOT5 and above are silicone-based, so don't absorb moisture but can give a slightly mushy pedal, thus tend not to be used on track cars.
do you have any quantitive proof instead of another persons opinion on another forum?
In my experience it doesn't seem to. The majority of track day goers seem to enjoy spending money on super-fandango bits and bobs though. Stuff like Magnecor leads and other such stuff. OEM is often just as good at the start of its life, and if you use an appropriate service life for the application. There's a lot of BS around uprated parts, but if they're shiny, or pretty or you can lean on your bonnet and say 'oh ya, I've fitted this super brake fluid and it's like amazing because my lap times have come down by three tenths of a second'.
You could actually stand there and say 'I change my standard brake fluid once a year and it hasn't ever boiled' but that doesn't sound nearly as cool or expensive.
After all, if you boil the super-fandango brake fluid six months after putting it in the system, you can stand there and say 'I went SO fast I boiled my super-fandango brake fluid' when actuallyit boiled because it had hoovered up the moisture while it stood for three months between track days and the now-wet boiling point was lower than the dry boiling point of the straight-outta-Halfords DOT4 5litres for £20 which you might have put in instead.
Anyway, I've got this amazing electric supercharger if anyone's interested..... tuning parts, not remotely full of unnecessary expense and false benefit.

well thats you all over thomas
everyone's wrong except you
jeez even your mate danny p uses uprated pads and i know for a fact you get your rod on over his car knowledge.
So does anyone else on here use standard pads for trackdays out of interest?
you might want to put the electric supercharger on yours, it's obviously not powerful enough for its extra weight if you don't need uprated pads
