I am wanting to get a dual disc Southbend clutch(#3600). Do I need to get one with the SFI approved flywheel? I can get one with a ductile flywheel for around $400 less. I am not going to be doing any sled pulls. It is going to be a daily driver with a little playing now and then. I have almost all the stuff that I need. I think the clutch is one of the last things that I need to get.
Here are the mods that I have ready to go on my truck MPI twins(64/480), Flux 3's, F1 springs, II dual cp3 kit and ARP 625 studs. I also need an Airdog and a Smarty. Thanks

If your not going to be in an event which doesnt require SFI, seems like a no brainer to get the ductile flywheel, which I have and it holds great so far

Nope you really don't need the SFI spec unless your pulling, my truck is about to have one go in to.

I have no near future plans on doing any sled pulling, but I got the SFI approved flywheel just in case that I do want to pull and b/c it's added insurance. The clutch discs and spacer plate will be SFI approved, so the flywheel might as well be also.
