You can tell that there's no momentum (rotational inertia? rotational momentum? It's been awhile since I had this terminology in my engineering courses) with an aluminum wheel. I had a Fidanza 14lb wheel behind the 428 in my Cobra. I noticed that I had to slip the clutch more taking off from a deadstop to keep the motor from bogging....compared to the steel flywheel that I had. It seemed like the steel wheel would almost let me just let the clutch out without giving it any gas from a dead stop.

I think for someone that's driving predominantly on the street, there's no need for an aluminum wheel. For what it's worth, it could lengthen the life of the clutch.

They are also quite a bit more expensive. A good billet steel wheel is around $200 while the aluminum wheels start at $330. A McLeod aluminum flywheel is closer to $500 I think.
