Not to get too technical, but losing 10 lbs on a wheel has a greater positive effect than losing 10 lbs on a rotor. Because the barrel of the wheel is further away from the rotational axis of the axle. The further out away from the axis the weight is lost, the greater the benefit. But losing 10 lbs on a rotor closer to the axle still helps quite a bit.

Less weight = better response.
I understand the concept; I was thinking along Black Betty's reasoning, but I guess 10 lbs is enough to make a difference.
These are not required for street cars. I can see the need if you are tracking your car on a regular basis and need better stopping and unsprung weight savings.
