Flywheel Balancing 1992 ZR1

[jerrydirks]

I have recently discovered that there are no weights in the flywheel and there is noticable vibration above 5000 rpms. I have the flywheel out of the car, were the weights meant for balancing only the flywheel or was the balancing performed for the flywheel and engine combined?

Would having the flywheel/clutch balanced alone be sufficient?

Has anyone had there engine and flywheel balanced in the car?

Any help is greatly appreciated!!!!!!
