ACT Prolite Flywheel or Spec Aluminum Flywheel

[smoke187]

i myself am going with the 13lb flyinmiata flywheel for street ability

[Skuce]

You already have a Miata clutch right?

[Kitty]

is the FM flywheel just a stripped stock flywheel?

yes i do

I myself have a fidanza 8.5lb fly and it is a huge diff compared to the stock unit. Im actually thinking bout selling it though, and getting the spec stage 3 miata lightenend fly, and lightened pressure plate, thats deff something to look at with fly clutch kits, because the majority of the weight of the press plate lies around the outermost edge of the fly so if you get a light fly but a heavier pressure plate your kinda negating the light fly, spec makes a lightweight fly/light weight pressure plate that would be a flippin sweet combo I beleive, as far as drivability goes, once you know how to drive with a light fly its not harder to drive its actually easyer.

[smoke187]

you don't want to go to light for a street car traffic and light weight flywheels suck

[swalltr207jg]

that's why u have neutral, and its not an issue with a 8.5lb, so I highly doubt itd be an issue with a fly/clutch combo that's a few lbs lighter

I've got about 400 miles on my ProLite flywheel so far, mix of street driving and track use. We even had to pull the tranny once since it was all put together, I think it's a great flywheel. I'm not having any driveability issues with it at all. The clutch isn't anything too fancy, just an Exedy Stage 1 kit for the Escort GT. I started out with one for a Miata, but due to some kind of issues with it, manufacturing or something, we changed it out for the Escort version.

I'd be interested in it if you do sell it

[swalltr207jg]

ill let u know

Every time I go from my truck to my car I seem to rev the car too much for the 1st couple starts as I'm used to a less revvy v6 with a heavier flywheel. I assume the same would happen with a light weight one so for driveability's sake I wouldn't get a light weight flywheel at all but thats just me.

Meh. A little practice on starts and a light flywheel is fine.

Hm, kinda ressurrecting this a bit.

For my '85 corolla, I ended up getting a 1-piece 8lb9oz chromoly unit, that came with a good clutch, throwout bearing, pilot bushing, and alignment tool, for 500 shipped. great deal!!

I'm thinking maybe the ACT streetlite 11.4lb miata flywheel, for my '90 4WD (the least expensive of the three weights offered, 10.4, 11.4, 13.5lbs). I need to replace the clutch, and I'm sure I'll be rallyXing and autoXing it at some point. Plus, It'll get a BP, and possibly even a turbo eventually, but until I get one built for it, I''m just going to be using the B8, so any improved ability to spin faster will be great.

Jay, you said you used a 93 MX6 ACT clutch on the fidanza, right? Is that just because of greater friction area?


hmm, I was just digging into it more, and the "Flyin' Miata clutch Happy Meal", with the 10.3lb steel flywheel sells for $699, and comes with the ACT clutch (rated for 233lb-ft), their little clip for blocking off the clutch switch, and the throwout bearing and pilot bushing. I think the throwout is different, so I'd need to source a new one of those, but I think it comes out to be a pretty good deal.

i am looking for a used aluminum flywheel.hit me up with a message if you have one.

Corksport did some measuring and found that that combo has the proper clearances and such to not overstress things like the clutch fork, and puts the loads on the shafts in the right places. It also has a bit more surface area, yeah.
