Cobra 29,
As you have said, the aluminum flywheel, though lighter, still retains the stock diameter so the effect will not be that noticable. Where as the low moment of inertia units, as DavidNJ has said, are much smaller in diameter. These units have very noticable effects due to the much lower polar moment of inertia. I've run an aluminum flywheel on the street and found no drivability issues at all. I now run a 7-1/4" low MOI unit and can't say the same anymore.
