Waiting for our new flywheel from Summit for the T5 conversion. Do we need to have the friction surface machined at all, prior to bolting on the clutch/pressure plate assembly? Seems like I read something to that effect, that it needs to be "roughed up" a bit, prior to first use? TIA

I've heard people say the same thing but have never had to do that. I would think the only reason you would have to resurface a brand new flywheel is if it was warped after it was machined.

The face on a new one should have the original surface grinding marks and I just clean it with brake clean and bolt on the clutch. Never had a problem that way.

Centerforce recommended only cleaning the new flywheel with brake cleaner to remove the preservative coating. There was a discussion of this issue which should be available with the "search" option.

Thanks dude, works for me. Nice to hear someone's acutal experience.

I was in a machine shop in Stockton and the guy there recommended surfacing a new flywheel. His point was that when the flywheels sit in storage, stacked on top of eachother on pallets or whatever, it is possible they can warp. hmmmm. No harm I suppose. ON the other hand, I did not resurface my centerforce flywheel. I did, however, do something I read about. I took a die grinder and installed a "scotchbrite" type disc in it, then went over the flywheel in a counterclockwise direction. I read to do that with flywheels and rotors. Don't know whether it made any difference. My advice is generally as good as the last article I read or the last mistake I made and corrected. hahah.

Never hurts to check a flywheels flatness with a straightedge and feeler guages, but, IME, the OEM's have better surfacing equipment than most shops other than the large rebuilders. The Blanchard finish that comes on an OEM flywheel is all you need for good clutch performance.
Check it, clean it, install it...be sure to use new bolts, check your throwout bearing and use some Permatex #2 on the crank bolt ends, if the crank hub holes aren't blind...

Good luck!

It should work just fine if you just bolt it up, but as camachinist said, it never hurts to check. We had to resurface the pair of brand new heads that I ordered because they had a little "washbuckle" type effect in them.
