I've used DBA5000 324x32 on a 260kw/1500kg GTR with standard Brembo calipers, 3" ducting and Pagid RS12 in one tarmac rally... the red paint turned white (cream) on the first stage, and two stages later they were warped with the same seen after each stage.
The same set up, the actual whole front brake kit (with skimmed rotors) including 3" ducting but with Pagid RS4/2 was then put on a 225kw/1100kg GTSt and even after a 10 lap race at Symmons Plains the green will go cream but the orange remains orange.
