Love this stuff. Even Motul 600 wouldnt hold a candle and I would get it all mushy when pushing 9.9/10 (this is a time trial car which I would run in open track as well). For most stock caliper/rotor application, I have found fluid to be the weakest link (assuming you are on track pads). Even on the M3 when it was a DD, nothing worked better than the SRF; once a year flush as safety. On the M3 I boiled the fluid and it got a fair bit mushy but surprisingly "came back". Fluid did check out a bit dark during power flush but that was pushing it for a long time on the track with a passenger.
