When I'm idling at a complete stop in neutral (M6) i feel a slight vibration from my elbow resting on the center console that feels like its coming from somewhere along the drivetrain. When I rev it up the vibration gets stronger (both with and without the clutch pedal pushed in if that matters). And when I get up to (legal) highway speeds the vibration is strong enough so that I could feel the seat vibrating against my butt as well. I popped the hood and the engine didn't appear to be vibrating very much. Since it even vibrates in neutral I figured it's probably not the transmission, driveshaft, or rear. Could it be the clutch and/or flywheel?
-Thanks in advance

If it's the pressure plate bolts backing out it could cause a serious loss in performance. Like your clutch coming from together at a high rate of speed. I would pull the tranny and give everything the once over. Also, get your flywheel and pressure plate balanced together before you put it back together.

I had very similar problems in my 98, just got a new clutch with a new prebalanced flywheel and that solved the problem. Your flywheel is probably warped, or out of balance. Check out getting it resurfaced, or just getting a new already balanced one from gm parts direct. Anyways good luck hope this helps.

You might also have a wasted pilot bearing. I just did my clutch this past weekend and found the needle bearings and housing that holds them ground away. Little needle bearings all in the small space of the crank. So, cheap part to replace, but bitch to get to. FYI - get the pilot bearing removal tool and slide hammer from AutoZone. Took me two whole minutes to remove the old bearing!!

Did you get our clutch checked out yet to see if it was your problem? I think this might be why my car vibrates at idle when I'm in neutral. Let me know your progress.

My car's at TTPerformance right now getting a roll bar installed. Once it's in they're gonna find out what the problem is. I'll make sure to keep you guys updated

If you want, I can post pictures of my pilot bearing after 5 days of driving the new system like a BABY...but you prob. wouldn't be able to recognize the pilot bearing anymore - worn out, metal shavings everywhere, and crazy stupid vibrations.
I'm willing to bet you have a balancing issue. I resurfaced my ORIGINAL flywheel and put the Spec 3 back in with a NEW pilot bearing. Everything went back together just fine and immediately noticed a very very smooth idle. HOW-FREAKIN-EVER, it seems that the vibration is slowly creeping back. This leads me to the pressure plate! Call Spec and see what they say. That's what I'm doing on Monday.
Hope this helps, at least you aren't alone, lol. I'll post when I find the solution.
