I am not sure. I have heard enough anecdotes to where I would not use SRF in anything but a dedicated race car that got fluid changes every few months (or events), which would be very expensive with SRF.
If you are experiencing fade, I would seriously consider brake size or pad upgrades. If you have the small 300mm fronts, that's the problem. If you have the 320's, toss those YellowBox pads and get some R4 pads or something. I think the ATE fluid should be adequate. If you do need something more, I would strongly lean toward the Motul fluid. It's more expensive (about $25/liter) but does not have the negative side effects of the SRF.
I use the ATE (SuperBlue and Type 200) in my cars, btw, with R4-S pads, but I have not been to the racetrack (not counting the dragstrip).
