Hey guys, when I changed my clutch a few years back, my tech said my stock flywheel was "borderline," but that it would probably be fine for a while. Well, I'm planning to do the gt2 slave conversion, and so I thought I'd upgrade my clutch to a stronger unit, but figure I should definitely replace the flywheel this time around.

So here is the question: I found a used flywheel on CL that is represented to have less than 3k miles, but it looks a little rough (pics below). I've spoken with the owner, and he insists the low mileage is correct as the flywheel and clutch came out of his friend's car when he did a bunch of mods. What do you think, looking at the pictures? Safe bet? (the thing is cheap, so Im tempted to take a chance). Thanks!

 

There are two things that can be wrong with a dual mass flywheel first is the flywheel surface that the clutch disk bites into with having a micrometer to see the thickness and also spining the flywheel up to see if it's still true or not warped.

Next is the dual mass assembly this can wear out and no long do the balancing action of the vibrations

The surface can be machined but you won't find many that will do it on a dual mass flywheel

 

Contrary to popular belief, Dual Mass Flywheels can be resurfaced. I would only do it once though. You have to make sure that when the machine shop does it that they machine the step to maintain stock step height between the surface that the pressure plate bolts to and the friction surface. Very important to do this so the clutch doesn't start slipping prematurely. You also want to check the amount of lash between the center flywheel and the outer part. They will move a little, but I would ditch it if the lash is excessive. A good clutch specialist or even a transmission shop will know what looks right on that part.

 

Thanks guys. If the representation is true that the unit has less than 3k miles, I should be fine. Doesn't sound like the appearance of this unit (a little rusty) is any indication of its operative condition.

I can always let me installer determine if its acceptable (I'm going to have evoms do this work). Thanks guys.
