Aluminum flywheel.... new clutch? - ZR-1 Net Registry Forums

zr1assassin · 10-17-2018

Thinking about swapping out to an aluminum flywheel, do you have to or need to get a new clutch when swapping flywheel? Car a 92' has 20k miles so I'm assuming clutch wear is minimal.
Looking at a fidanza 198551

FYI: converting from a dual mass flywheel will result in transmission rattle which is loudest when in neutral with clutch engaged.
The Fidanza FW weighs in at 13-14 lbs
Jerrys Gaskets has custom manufactured aluminum FW’s at both 18 & 22 lbs. read more about applications & benefits;

My fidanza sounds like a sawz-all at times up until 2,500 RPM......All though the motor will spin up much faster .....The gear rattle in neutral really doesn't bother me......I hear some have used a sprung hub disc to mitigate the noise.....

No,stock clutch can be used....I did and I was at 46 k...

Just swapped out flywheel and that's it?

I have Fidanzas in three cars. I'd follow Jerry's suggestions.

If you choose Fidanza, I would replace the clutch disk and make sure it's a spring hub and minimum thickness. Be sure to clean the frictions surface on the flywheel.

Recommendations on a disc/sprung hub?

I think I have a Fidanza for sale. I might have sold it.
