Dual Mass Flywheel Conversion feedback
My '94 Corvette is in need of a clutch replacement. It has 117k on it and as far as I know both the clutch and flywheel are original. Since I know the Dual Mass Flywheel can't be turned, I figure that it is better to go ahead and replace it too. Unless I just have it sanded down.
I am thinking of going with Eckler's corvette clutch kit dual mass flywheel conversion (at $360), along with the dual mass conversion flywheel (at $160). Does anyone have any knowledge of these parts or Ecklers Corvette?
Ecklers also has a clutch kit, that would be used with the original dual mass flywheel, I just don't know if I want to rely on it after 117k..
I am also thinking of replacing both master and slave cylinder at this point and not have to deal with it later.
Thanks for any help..

Call them and ask what brand of parts they sell for these two kits. You’ll get better feedback on the part versus the retailer.

It's the little things. Read all the recent posts, and an alarming thread seems to appear. A great many clutch jobs seem to go south not so much because of clutch disc / pressure plate / flywheel issues, but rather clutch fork and clutch fork mounting ball pivot issues. simply stated, these parts are subject to wear but unfortunately seem harder and harder to find, especially the mounting ball pivot. I would not recommend doing a clutch job unless I had these replacements in hand, or at least had verified a source for these parts if needed.
The other route would be to convert over to a push style clutch utilizing a combined internal clutch slave cylinder / throwout bearing; pricey, but this may be the wave of the future unless OEM style parts become available.

I saw the Eickler's ad but I couldn't figure out who made it so I went with SPEC's flywheel (extra mass) and a Stage 2 pressure plate as it comes with a heavy duty made in USA throw out bearing purchased via IMPerformance.com. I had about 3-4 exchanges with SPEC's technical support which was very positive.
Although the extra mass flywheel is supposed to eliminate gear whine. It did not. I'm looking at using a different trani oil to see if that will get rid of it.
Any diesel shop will know how to resurface your DMF if you're happy with it. That is probably your best bet costwise. You'll need a sprung hub clutch. I'd go with SPEC just to get their throw out bearing. The made in China one's are junk.

went with the spec setup also. Stage one. so far 2 seasons of autox abuse and it holds up. I got the lightweight fly and it lets a little stink out everytime I let the clutch out. I was worried about it till I pulled the motor and I still have quite a bit of material left.
(this is a 2 driver car, so really about 4 seasons worth of beatings)

Looks like they use Carolina Clutch, so I just went to the Carolina clutch site and they use Valeo for the standard stage 1 clutch, and use their own Carolina clutch brand for the stage 2 clutch.
With the stage 2 clutch, you have to get the 1 piece Billet Steel flywheel. I am leaning towards getting the stage 2 with the new flywheel..
although if I go with the stage 1 from Valeo, it's a lot cheaper.

Doesn't surprise me. Ecklers may have the highest markups of any vette specialty retailer.

I have an Eckler's flywheel...sitting in a box in my basement storage. When I first installed it, I had mistakenly blamed it for the fork hitting the pressure plate, and ordered a Spec lightweight wheel. I'm not sorry for doing so.
The Eckler's wheel is iron, I imagine this would be why it is half the price of the Spec wheel.

I have the Mid America system that they sold back in the 90's...it uses a Camaro single mass steel flywheel and has a specific ball stud that is about 1/4" taller than stock to make everything line up properly.
It has worked fine for me for over 17 years...but I'm pulling it out and replacing it with a McLeod Street-Twin. The CenterForce clutch has had a good run for 35k miles, and considering the abuse I've subjected it to...I'm pretty happy with that. I don't drag race it...so clutch dumps are very rare.
I should be putting my single mass flywheel & pivot ball in the For Sale section soon...flywheel needs turned and ball stud still looks (fairly) new.
