You can probably get an aftermarket clutch and solid flywheel kit for less than the cost of just a new flywheel or just a clutch from Ford, and for the labor costs you might as well. It was the best thing I did for my turbo outback. Dual mass flywheels are supposed to help get smooth launches, but it just masks the clutch engagement point. For now you can try letting it out smooth and quick, and only apply throttle right at the end.I actually forgot about this post for a while - sorry for missing your reply. My clutch issue seems intermittent. I suspect the flywheel is going bad.
I am considering doing a single mass flywheel, but I'm told I will regret it. Not really sure where to go from here.
You're almost out of power train warranty so you can see what will be warrantied while you can (and risk leaving your car with a dealership). Or just get a nice clutch/flywheel setup. Then get a conservative aftermarket tune and see if that helps your other issue. Hope that helps.
