I drive a 1994 camaro z28. I recently just got an aftemarket clutch and flywheel installed along with billet steel pulleys from march. The clutch is a stage 2, 6 puck cutch from clutchmasters. The flywheel is also from clutchmasters and weighs 22.5lbs, it is cromoly steel. The pulleys are alternator and underdrive. Now for the problem..... Since the install, whenever I reach 3,500 rpms in any gear I get extreme vibrations. It seems to be coming from the engine, but nothing is confirmed. This did not happen before the install of these parts. I contacted clutchmasters and they claimed that vibration is normal with a 6 puck clutch, but it just doesnt feel right to me. Any driving under 3,500 rpms is perfectly fine. BTW the clutch is not fully broken in yet, 350 miles since the install. If anybody has any ideas what the problem could be please let me know, anything is helpful.

Yes. I advise you should have put this in Tech Talk.

1. Did they balance the flywheel?

Is the automatic trans flywheel different than manual one? I could see them sending you the wrong one easily.

I'd check all motor/ tranny mounts..

You may of gotten different weight on your flywheel then what your motor is balanced to. Which would cause this vibration.

Also they may of not installed the 3 little pins on the flywheel either, which would also cause the vibration.



Either way, tranny has to come back out for you to fix the problem, id start there.

Probably a mixture of the pulleys and new flywheel throwing off the balance. You're gonna have to pull the trans out anyway. When you do that pull the pressure plate off just to see if it chattering has any uneven ware. If it doesn't call some machine shops and see if they can balance it for you.
