"Most"? BMW says 20% of M2's get tracked. That sounds about right to me.
The additional weight is minimal. The movement of the center of gravity lower by reducing weight up top is more significant than losing a few pounds. That said - it's still not much of a difference. Is any track rat really going to enjoy their track sessions less because they have a steel roof? Are their times going to suffer measurably? Probably not.
Less headroom is also factor in some not wanting a sunroof. If you're tall and wear a helmet, losing ANY headroom can be a real problem. Also a lot of people don't like sunroofs because they can be problematic. A lot of people enjoy an open roof and couldn't care less of some barely measurable "loss of performance" that may exist because of its presence.
Bottom line - it's great to have choice. If BMW is for some reason really sticking everyone not opting for the expensive CF roof with a sunroof, that's a really odd decision.
