i thought i read somewhere that some clutches might not work as well with some flywheels or vice versa. I'm not sure so don't quote me on it. But, since you're going to get screwed on the labor anyway, might as well have them do the flywheel as well. Or if you do it yourself you'll save you some time.

no, you could just lighten your current flywheel a little bit but I recommend not getting a new one.

general thought is since ur there when u open up ur tranny might as well but if ur flywheel looks OK then it will save u some money.
but then when its time to actually replace ur FW then u have to open ur tranny back up.

just do it once and get it done with.

so it all depends.........

ok heres the deal, my clutch was slipping on the highway the other day when i had all my parts on, full catless exhaust, vf23, unichip, and i took it into the dealer. I was also having porblems with the first gear synchro so he said that i would only have to pay for one hours worth of labor on the clutch replacement since he transmission was already open for the synchro thing. But a new element has been added. He told me to get an aftermarket clutch. And one more thing, since the parts have come off i have had no clutch slip. what do I do?

ur clutch just could of needed adjustment which they did when they took it apart.
change out the tranny fluid and replace with synthetic

buy ur clutch,PP, and FW and when the time comes replace it. otherwise keep on driving til u have no clutch at all.

is ur synchro fixed?

If your clutch was slipping on the freeway it's very close to not holding in any other gear. I take it it slips only at full throttle? You can "screw" the buyer by just taking all of your parts off and it might or might not slip on the freeway anymore. You CANNOT resurfafce your stock flywheel. You DO NOT have to open the tranny to replace a flywheel. You pull the tranny out which takes about an hour and a half and about 15min to replace the clutch and flywheel. The only thing is you probably have "hot-spots" on the flywheel which causes clutch shudder. If I were you, I would save some money and just replace the clutch disc, which is $149 from the dealer or $99 from Subaruparts.com. If you are planning to sell the car, keep the flywheel in there. If not get a HEAVY, NOT light flywheel. I would NOT get any lighter than 16lbs.

Hope this helps and clears up the previous innaccurate posts. (no offense)

It basically boils down to what the flywheel is made out of and how it's surfaced, then matching it when other clutch materials. So, yes, you are correct.

I think the reason why you have not encountered the slip after removing the parts is because w/o them, the engine is not creating enough torque to cause the slip in stock form. I am assuming you have tried WOT to test for the slip since removing the parts. In that case I assume the slip will return when you reinstall those parts.
I think that the clutch manufacturer is the best source to find if you really need to replace the flywheel. Unfortunately, I suspect they will be biased towards suggesting to replace it with a flywheel they manufacture, etc. I always assumed that if the flywheel is not replaced, it would still need to be resurfaced, similiar to brake rotors. This may lead to a lighter flywheel.
