Wheel weights

I just had a guy on another forum ask why heavy wheels (or hubs) are a Bad Thing, IOW he seems to think that heavy wheels are not a factor concerning performance of a street machine. Is it not obvious?

Is it something like throwing a frisbee or throwing a VW wheel like a frisbee. One will spin faster, easier and fly further than the other with less effort on your part. ;-) Usually the lighter one moves quicker to changes in direction too, like up and down over bumps.

Heavy wheels are usually harder to damage and should be great on off-road vehicles or vehicles that don't need to go super fast.

I could be wrong here though! :-) JMHO

With heavy wheels there would be a lot of "gyro force" in the spinning wheels. It would go straight and turning the wheels would be a lot more difficult. With the wheel spinning the effect is a lot bigger than with just static mass.

Weight (mass) that is on the other side of the suspension from the body is referred to as un-sprung mass. Your suspension and steering components have to deal with the un-sprung mass.

If you increase un-sprung mass, you better beef up the suspension to cope with it.

Otherwise, the handling of the vehicle is compromised, a BAD THING in emergency situations.

Instead of the dog wagging the tail, the tail tends to wag the dog.

Other effects are increased wear of the suspension and steering components.

The vehicle was engineered for the stock wheel tires brake components.

Big changes to any of those will have big consequences.
