I don't buy this.
Putting super special fluid in a track car is nonsense.
It's like putting super special oil in a track car.
However many track days you do the fluid will still have collected enough moisture that it will need changing at two years. The super special fluid becomes a very expensive consumable, with no benefit.
Change your fluid regularly (as you should) and you shouldn't be boiling your standard fluid.
If you're still boiling your fluid then review the specification of your brakes, or your driving style and brake less - it only slows you down anyway.
I have to say I'd take the same stance on pads and discs. Spec the correct, or over-sized brakes and use OEM quality discs and pads. If they aren't working for you then you're either running about 3-400BHP or your braking style needs attention.
Obviously this is only based on my own limited experience, but since fitting 280mm front brakes to my Golf I've never had any brake fade, but then I drive pretty slowly in comparison to some of the hot-shoes in this thread....
