I am curious about the weight differential, does anybody actually notice the difference in weight and any change in driving performance?
Reducing unsprung weight and rotational inertia are both good things, which physics tells us should respectively improve suspension reaction and acceleration.
Whether anyone notices is hard to say. Depends entirely on the sensitivity of the observer.
When I changed out my steel sprocket for a Supermax unit, I found the rear suspension to be less harsh over sharp impacts, but couldn't feel the difference in acceleration, perhaps because the sprocket weight is relatively close to the wheel center.
