i have a dual mass flywheel and I need to get it machined, but because of the springed center the flywheel will turn turing resurfacing and the lathe will chatter on the surface....waht options do i have, will some machine shops be able to work around this?

Can i just get a single mass and will it work in place of a dual mass without changing anything else

Note: I have supereta stock lower end and tranny with no reference sender or harmonic balancer on the flywheel, so no sensors are there

Any decent machine shop should be able to do this, if this is the excuse that he person gave you then he's just fishing for more money. Did you tell him that it's from a BMW...could be why.

I took mine to a shop and all he told me was that the only problems that could encounter was having metal shaving get into those springed center openings.

Yeah, you can replace it with a single mass as long as the clutch, pressure plate, and I believe throw out bearing also get replaced with single mass specific components.

Just get a clutch kit from sach for single mass, get the flywheel too from an early "I" if you can, if you have it already then your good. about shaving it down go for it, independent places sometimes make excuses but napa should be fine. I see your boosted, I hope you have a longer ratio diff cause that flywheel will spin real quick, plus you will love the bottom end torque feeling, I'm running 4.10 lsd. ripped 2 pressureplates from misshifts, scary indeed.

see the thing is I already have a nice spec 3 stage 3 clutch kit for a single mass flywheel...

If you already have the clutch kit for the single mass, buy a single mass flywheel, get it resurfaced, and you're good.

The bolts can be used one time only.
