well, it does make the car a little harder to launch. and depending on how light you go, the revs could drop super fast when pushing in the clutch. for some people that like to drive s2000's like pickup trucks, that might be a problem.

it should be noted here that it's not just the flywheel that affects these things. it's bolted to the pressure plate as well, and some clutch systems include ultra lightweight pressure plates. in theory, you could get the same effects by lightening the pressure plate instead of the flywheel. anyway, i drove a Carbonetic single clutch, and i think that system has the lightest flywheel + pressure plate combination available (~17lbs!!!!). as soon as you push in the clutch, the revs drop to the floor. you basically have no time to shift. just tap the clutch while moving the lever. best shifting system ever.

the carbonetic clutch is an extreme example of the effects of a lightened flywheel. but some people can't handle that quickness.

Some people don't want to deal with that in a daily driver; you know, the folks that don't live their lives a quarter mile at a time. Its important to know what making changes will do elsewhere, something too many people never think about.

Saki - the Torque equation is derived from the Force equation. Again, the fundamentals of your point are well demonstrated by the force equation, but the subtleties of the torque equation obviously take into consideration the variables that accurately depict the relationship. It's not to hijack your point - it's only meant to refine the principles.
