Jeff's did not have the BBK, either. And he and Hunter were pretty darn close, despite the difference in brake calipers.
Sure. Peter, Mike, and Bryan all have race-prepped NSXs - with roll cages, lexan windows, stripped interiors, etc. Within that "money no object" context, sure! As long as you're going to spend tens of thousands of dollars prepping your car (and making it unusable on the street), you may as well get bigger brake calipers, too (although I seriously wonder whether the weight reduction makes the bigger calipers even more unnecessary).
And I find it funny that you write your post in this way, as though you are trying to make me look slow by listing only the instructors (who are indeed faster than me, although FWIW Wiggins and I are pretty close, and his NSX is a Zanardi). Nice move, Steve - really classy of you...
