Nodular iron vs billet steel flywheel?

[MarkVIII93]

So I'm getting a new clutch soon and I'm trying to get something that will stand up to serious abuse (5k launches). I have a 26 spline input shaft and I'm limited in my options. The level of clutch I'm looking at calls for a billet flywheel. I'm just curious as to whether it is absolutely necessary for a 300-400rwhp car.

billet should be sfi rated. How much do you like your toes

Go aluminum, it will help the engine rev quicker.

I've heard some low end grunt is lost as well. 456s should counter that though? I may end up going with a billet steel piece just for affordability sake.

I have aluminum and w a 4.6 it would have helped more if I had stayed iron or upped to billet

I think the steel is going to be my best bet as far as affordability and longevity.

If you're serious: Billet

There is a reason there are no SFI approved cast iron flywheels.

Do you mean iron? I may just do a billet piece to be safe.
