Been reading about this on all different car sites.

It seems some manufacturer's flywheel / clutch assemblies, intended for internal balance crank assembly, do NOT have good neutral balance.

McCleod, Spec, others.

If seems to be agreed that balancing your flywheel and clutch separately from the crank is a good idea. Even separately from each other, flywheel, then clutch.

Not every machine shop is equipped, or is willing, to do this.

Anyone know of particular shops that will do flywheel / clutch dynamic balancing ?
