My info says 89 to 96 are the same flywheel. If you use the Fidanza the tranny will be a lot noisier though. I think its worth it for the improved throttle response

Why is the aluminum flywheels so much louder? Are you just not getting them balanced or what? I don't understand why they would be louder?

It's the noise that is inherent in our ZF trannys. The reason GM used a dual mass flywheel is to dampen that noise. going to a single mass lets the noise be heard but doesn't hurt anything.

Yep, it'll fit, just make sure to match balance it to the DMFW.

I've known TWO C4 owners that chose to go back to heavy as well,
so I never tried it myself. Stuck with my DM and spent $ on tuning.
Now my motor revs just FINE.

I have read that the fidanza's come with weights that you just have to put in the same place as your stock dmfw, is this correct?

I used a stage 2 clutch. I dont know who its made from because my auto guy did it for me. (order and install)..Its not as lud though if u have gears. Since my 4.11's got put in, My flywheel calmed down. I think because my rpm's are higher

I was supposed to get an OEM flywheel from a guy on here and he dissapeared after He asked where i live and told him, he'd say he'd write back and let me know how much for shipping and then well go from there. but nothing.
