There have been true dyno tests done stating that it does affect speed. Specifically a lighter rotor will have more rpm a quicker acceleration and less torque. And similarly the opposite is true for a heavier rotor.
I think the scale is important in some of these 1to1 comparisons, because some of the stuff that we do in 10th scale really wouldnt work in a full sized racing car.
