There's not a ton of difference in cast vs drilled iron rotors. You remove one issue only but leave all the rest.

190-210? On what track? Daytona in a fully prepped ALMS car? (which doesn't use drilled rotors btw)

And once those rotors get replaced on those track cars that I see at the track all the time, blanks replace the fancy drilled rotors a lot more often than they don't when people can find them.

Carbon brakes see some race car use, but it's limited due to the insanely expensive costs associated with them. Even Porsche themselves don't want to pay the price of admission on that one.

Do a search for people that track cars that come with those rotors and see what's popular there. The fact is that TypeR believes the hype that removing mass and adding a lot of stress points to a rotor somehow improves braking. That is simply not true. It does have other negatives that you'd see with track use, but for a lot of people who buy said cars they don't really get tracked anyways. Hell Carbon brakes work great at temp but not so great cold and result in longer stopping distances in some testing yet there are people that run them on cars that are intended to be 100% street cars.
