I think I recall seeing 1# rotational is worth 4# of unsprung. but if its both rotational and unsprung as a wheel is its worth 10# of static wieght.

also for handling its best to remove weight from the top of the car ( 11# CF probably equal to 46# savings in an exhaust) and its worth more in handling to remove it from the ends of the car than the middle (moment of inertia of the car ie turn in).
