One of my local tracks CMP is notoriously bad on brakes though, Ive seen a GT500 mustang in the sand pits with its brakes on fire .... , brakes when your stopping from 150 are not the things to save money on IMHO.

I'm running R -888 tires, PF-06 pads on stock calipers/rotors in Group A and instructing at a variety of road course venues such as Pacific Raceways, The Ridge Motorsports Park, http://www.ridgemotorsportspark.com/
Spokane Raceway Park http://www.spokaneracewaypark.com/
Portland International Raceway, and Oregon Raceway Park http://oregonraceway.com/
I'm not supercharged and I don't drive 9/10ths at a driving school; I save that for racing. BTW we don't use SRF in our race cars either. Ate and Motul with frequent flushes has never let us down
Of course if SRF makes you feel more confident at 9/10ths then by all means go for it.
Keep in mind that if you're driving fast on a track, even in a school environment, it's not a matter of if something bad will happen; it's a matter of when. And it's seldom if ever brake fluid to blame; it's operator error
