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 don't know of any lighter than the 1.6 Fidanza.

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

Relax, semantics.

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

Well, it's not for my Miata. ;)

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). |

So you're saying you give terrible advice? Noted.
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. |

Actually I think it might..... |
If you're not driving in stop-and-go traffic, ceramic disks aren't terrible, just really really not great. I went through two sets with a 90 minute one way commute in the SF bay area. It can be done. You might turn into a homicidal manaic if you have that commute. I didn't, but I think that was mostly chance.
|
How many miles did you get out of the ceramics each time, y8s? I'm leaning towards the replacement friction disks.

If anyone checks on this later, I'm providing an update.
https://www.miataturbo.net/attachmen...ine=1443951447 Got the twin ceramics in. Starting is harder, but not markedly so. More difficult all around, but possible to slip rather smoothly if taking great care. On the positive side, it seems to catch rev matched downshifts with more authority, it's a snap more like a gear meshing, instead of less solid immediate bite of the organics. TLDR: I'm actually pretty happy with it as a street, daily driver clutch. Just wonder how long it'll last, given y8s experience. https://www.miataturbo.net/attachmen...ine=1443951447 |
in stop and go traffic for more than an hour a day, probably 10,000 miles max.
in normal driving, maybe 30k max. It's pretty much inversely proportional to starts from a stop. And it wears out the plates as much as the disks when you slip it a lot. So plan to replace all the surfaces (PP, floater, friction surface on flywheel/resurface) when you do a clutch job to save headaches later. And do lots of burnouts. That will totally reduce wear on the clutch.:party: |
I replaced the floater (949 includes it with new friction disks), got the flywheel steel insert resurfaced, but didn't get any new PP fingers (whatever the fingery part is called) though. Did you have any issues with that piece?
Thank you very much for your replies, y8s. :) |
on the tilton, the pressure plate springs press against a floating plate too. It has a circular pivot that dictates the travel ratio. I'm on slow internet and can't find the picture but it looks a lot like the plate between the two disks.
