How much power do you have mac? I'm running about 300rwkw on RE55s.
I have a similar setup to you... Stock Brembos on my R33 GTR, DBA5000 rotors, RBF600 Fluid, DS3000 pads, removed stone shields, Braided lines.
I killed my brakes when i was running DBA4000, Stock lines, RBF600, RB74 pads, still had stone shields on at Winton a while ago

You can see i turned my Brembo sticker orange like T04GTR said above.... what does this mean exactly? I have a rebuild kit ready to go through but haven't got around to having it done yet.
After that i changed to the DBA5000s/DS3000s/braided lines, removed stone shields and have done Sandown and PI since, and it seems to be ok - but i only do 3-4 laps in a session, not 7.... I don't think it would last that long.
I'm trying to get John@UAS to make some ducts/deflectors for R33 GTR which i think will help a lot. I found out the other day that Vspecs have some stock brake deflectors (smallish) and non-vspec don't.... Email him tell him you want some as well, the more people that do the more likely he will be to make some
