I cant say that I have tried a stop from 90+. I live in the Bay Area, CA, getting to 90 is challenging enough. Braking from that would cause a pileup of enormous proportions. Stay tuned to your favorite news channel tonight.
In all seriousness I got the street pad. There was a pad they offered that was one level up that might be better if you are concerned about brake fade. I do occasional twisties so the street pad was fine for me.
