I've no way to test it and prove it to you but if you are a racer you always want to reduce weight even if it is not by much. I have won and lost autocrosses by one or two thousandths of a second. You might not be able to feel it but the clock will measure it.

On my race car my rule is never put a part back on the car until I seek a way to reduce it's weight.
It's Newton's 2nd law .... the acceleration of an object depends on the mass of the object and the amount of force applied.
In my case (not a race car) the relevant mass is the total mass of my car, not the flywheel in isolation, and the accelerative energy applied to the car comes from the engine.

Cheers!
