If your putting a new clutch in... what determines whether you Resurface your stock one, get the steel one, or the Alum. one?

 

still wanting to know..

 

Have you resurfaced it before? Basically, what's going to limit you is how much they have to take off the surface (which shouldn't be much unless you have been really, really hard on it). There's only so much material you can take off before you can't shim it any more, at which point you'd have to get a new flywheel.

As far as the difference between aluminum and steel...well, the difference is the weight. If you like to drag race your car, you'll want to stick with the steel because of the inertia...a heavier flywheel will want to keep on spinning when you engage the clutch, helping you to get out of the hole faster. Aluminum will not, but should allow the engine to spin up faster (prolly good for road racing and auto crossing, where you aren't really launching the car).

FWIW, I did a billet steel flywheel when I installed my new clutch, and I only had 30K on the clock. I just wanted a better flywheel than the stock one...this one should hold up for quite a while.

 

Thanks for the info... I had found from searches that the Aluminum Fly wheel, was lighter and allowed the engine to spin up faster, but with more research I found that was'nt "always" a good thing... So I'm glad I did'nt buy into the Alumn. one without doing some research...

As for Resurfacing OR billet steel.. I have 43k on the stocker now, and the clutch is'nt show any major signs of wear or slippage, but with the new power it's just a matter of time... I guess it comes down to peace of mind really going with the billet steel over resurfacing... but it's early yet, and I still have time to look arround some...

So their were 3 choices, and now I"m down to 2... New billet Steel OR resurface the stocker...

 

If you have the money, get the billet steel one. If you are doing this on a tight budget the stocker should be fine.

 

You could also buy a new GM flywheel from ebay. I bought mine for just under $70 shipped to my door.
