The reason that I mentioned Road America is that on each lap going into turns 5, 12, and 1 with a supercharged S2000 you are doing well over 140mph and you might get near 150mph at 12. Turn 1 is a fast turn but you must break well for 5 and a bit less for 12.

speed isn't the main consideration IMO it is more a factor of hard brake events to cooling time. In my experience a couple really hard brake events separated by long straights or minimal braking is much easier on brakes than machine gun moderate events with no cooling. Take Mid-Ohio vs Gingerman, I have way less issues with stock brakes at mid-Ohio.

Blackhawk Farms Raceway makes both of those look like a walk in the park and I have no issues there. You must bring two sets of brake pads to BFR just to be safe on a single day event.
