It's 1.4x for rotors and the like, right? The flywheel is a lot more if my memory hasn't failed me once again.

There is no direct, defined corresponding number between sprung and unsprung weight.

Rotors aren't the best way to shave the MOST MEANINGFUL weight though, tires are, then wheels, then rotors, heading inwards to the hub.

No, but there's a rule of thumb I learned long ago, and promptly forgot. As much of an issue as this car has with brake cooling, I'd be wary of making the heat sink too much smaller.
