Most of those who track their cars won't have any issues at all using fresh off-the-shelf DOT4. That's what I've mainly used over the years, in 255hp 240Z (stock solid front rotors and calipers, 280ZX rear rotors/calipers), stock S2000, and 550hp FD RX-7 (328mm front rotors/ST40 calipers). Never any issues with soft pedal due to overheating off-the-shelf DOT4, even running the same fluid for three events/6 track days without bleeding.
Interestingly enough I tried ATE SuperBlue on the S2000 once, and on day two at Watkins Glen pedal started to get soft and I had to bleed. Since then I just run Pennzoil or Castrol DOT4. No problems.
