I don't know about RBF600, but again, I doubt that most will exceed the capacity of an off-the-shelf name-brand DOT4. I don't, and I've been doing this a few years...

On any single track day, you're spending hundreds of dollars in track fees, gas and amortization of consumables (tires, engine oil, trans oil, brake pads, etc etc etc) , plus risking total loss on a $25K+ vehicle. It wouldn't be smart to incurr in all those costs, and still choose not to use a proper motorports brake fluid.
In many cases it's just not necessary. Hasn't been in my experience, anyway, including in a 550hp RX-7. I've never had any issues running good parts-store DOT4 (usually Valvoline). I usually get at least 6 good track days before flushing with fresh fluid.
