Default Flywheel with a lower MoI than the Fidanza 1.6?

My twin disk is already dead, and the organic disks I bought aren't being made anymore...

So I'm looking for almost as good, and the 1.6 Fidenza isn't even close, but it's the lightest I know of. Any better options?

(tuned 2001, naturally asperated, no concern about torque, planning on a 1.6 ACT XTSS, mainly street, yes I want it as light as possible)

Is it the retired 949 organic twin that died on you?

Supposedly the clutch was designed for super long life in a high HP car.

Try out their twin ceramic?

You're not going to come close to that no matter what. The huge MOI reduction comes mainly from how light the clutch is since it is an aluminum pressure plate and the reduced size.

Mazdaspeed Motorsports has like a 7lbs steel flywheel but it uses a 5.5" diameter Quartermaster twin disk clutch that weighs less than 6lbs.

Or just buy the cera metallic replacement discs for what you have?

I'm aware nothing will come close to what I have. I've had both setups before.

The ceramic replacements, I don't see how they're not going to cause me issues on my daily driver. I bought the setup for the organics, now that they're in need of replacement, they're not around anymore. :/

I have heard that their are places can resurface your clutch discs.

I think I might have read that big rig or industrial truck shops can do it?

I have a badly heat spotted clutch masters twin disc that came in a car I parted out and I was pointed in that direction. Worth a shot to try calling them.

Call Rebello Racing. They used to rivet clutch material on their own custom disks back in the 90's.

Resurface =/= replace friction material.

You can't just rivet. You must bond the material as well, and nobody does that anymore. Hence the lack of discs for the clutch.

It's also worth mentioning that I wouldn't let Rebello touch my lawn mower engine.

Oh puh-lease.

It's a valid option. Whether or not you want to deal with Rebello is up to you.

I had discs made at clutchnet. Oleg was the dude who reluctantly did it a few times.

If you want a cheap option, I have a Fidanza/Tilton setup you can have for very cheap, but it requires modifications to work properly.

Still, after putting tens of thousands of miles on twin plates on the street, I wouldn't do it again (hur dur).

I've seen too much crap from Rebello twenty years ago to touch anything of their's with a 10' pole.
But, they're still around. And they've got lots of fans.

If you're asking what I'd do... I'd grab a set of replacement ceramic disks and deal with it.
It seems like you're going from champagne to Four Loko in your clutch selection. But again. Not my Miata.

Can we talk about Four Loko vs. Joose?

Erin, the only flywheel with a lower MOI might be the SuperMiata 1.6 flywheel at 7.8lbs. I've seen the Fidanza quoted at both 7lbs and 8lbs, so the SPM 1.6 part may or may not be lighter. You probably won't do any better than that.

The other option is ceramic discs, which are not street friendly. Neither option is going to make you perfectly happy, but those are the options you have.
