I get my flywheels resurfaced for $20, shop around for a good price, and yes you really should resurface it.

I sell clutches and turn flywheels all day eveyday so here goes what I think. I gotta chime in on this one.
If that ACT you are using is NOT a ceramic clutch,(and it's sounds like it's not based on the torque rating) be sure to resurface your flywheel. It will make sure the step Spec. on the flywheel is correct (should be -.065 on a D-series flywheel, or +.112 on a B series, I'm assumeing you have a honda) so the clutch will last as long as possible, and you get the max clamp load. As well as insure that it will not chatter.

If you are using a Ceramic (Puck) style clutch. I wouldn't bother with resurfacing unless the flywheel is burned really badly. The ceramic material is going to RAPE your flywheel anyway. Be ready to replace your F/W after using a ceramic clutch unless you use a stainless steel F/W. The main reason for resurfacing the flywheel is to prevent clutch chatter. If you are going to use a ceramic clutch it's going to chatter some anyway so don't bother unless the surface of the flywheel is uneven. You want to make sure you have the flattest area possible to provide the most surface area for the friction to grab onto. blah blah blah I could go on all day.

BTW, I did see someone say that a brake place near them will resurface F/W's. If they are doing it on a brake lathe this is the WRONG WAY to surface a F/W and you are likely to end up with more harm than good! (it won't come out flat) Make sure that it is resurfaced with a flywheel grinder. It's the only way to get it right.

ok its not a ceramic clutch. what dose the spec -0.65 (d series) apply to? and ill make sure the place i get it done at has a f/w grinder. thx for all the tips man explained alot

The pressure plate mounts on one "level" and the disc rides on a different level. They call this the flywheel spec.
On a D-series flywheel, the step from the press plate to the disc is down by .065 inches. So the spec is -.065.
The B series flywheel has the disc higher up that the press plate by .112 inchs. So the spec. is +.112.
This applies to all flywheels. Some are flat, some have a step, but it is critical that this step spec. is correct to get the max clamp and the max life out of your clutch.

BTW D- series engines are your single cam jobbies (most of them anyway) I'm talking about the code on the block. D16Z6, D16Y8 etc....

B- series engines are DOHC motors....B16A, B18C, B18C5 etc...

Don't be cheap and resurface that bitch. You don't want to drop your tranny twice. It just cost me about $50 and some change, it's good peace of mind.

ya i found out today when i bought my ACT clutch that Lordco dose it. its will onely cost me $15-$20 but my car will be of the road for 2 days
