soo.. what's the worst that could happen?

I'll be honest, the only solution to resurfacing the dual-mass fw I have is to ship it out and wait for another to come and pay a core-charge(closest shop that has a machine to do it is approx 130 miles away and they'll have to keep it for a week anyway).. I'm putting a spanking new O.E. clutch disc and Pressure plate on and the car will be completly bone stock since I'm trying to sell it.

I'm looking to avoid paying the $100-150 to resurface it. If I just use something like mabye a power sander to take the glaze off and a level block for fine sanding could I get away with it? As said, the car is not chiped, and is going to be sold so I'm looking to spend the least amount possible to get it out of my hands.

What's the worst that could happen by not getting it professionaly resurfaced? From what I heard it's only some FW chatter.. nothing major mechanical wise. There are no major groves on the surface, just normal wear from a 100K o.e. clutch.

The reason you would resurface the flywheel is to provide a fresh mating surface for the new clutch disc. The surface of the flywheel has been heat cycled many times from normal clutch usage. Resurfacing removes the top "layer" of the surface.

If you were going to change clutch material, as in a Stg 1,2 ... , then I would recommend resurfacing. If you're going from an OEM disc, and replacing it with an OE-style disc, I wouldn't worry too much about it.

The reason for this is the same as resurfacing brake rotors. The friction material doesn't actually "grab" onto the metal surface, it grabs onto it's own similar particles that are embedded into metals surface. That's why it should be resurfaced if you're upgrading clutch material.

Hope that helps.

yeah, sounds like I'll be fine, I am going from o.e. to o.e. and I'm already removing the top layer. It looks pretty clean so I won't worry about it too much anymore. Thanks.

No problem. It wouldn't hurt at all to grab a sanding block and some 80-100 grit sand paper and spend the 5 mins just "scuffing" it up a bit either. You won't remove enough material to compromise the angle/square of the mating surface, and it will help the new clutch break in time.

I went from an Stg1 to an OE-style in my Camaro back in the day w/o any issues, and I actually preferred the OE one. I forget how many miles I put on it, but it never slipped or had any issues for >30K of driving after that.
