Default Quality Control Not

Seems like either nothing fits, or it fails, or it's wrong; making repairs to my '96 C4 LT4 a challenge.

Just replaced clutch, & flywheel.
On startup the whole car vibrated and 2,000 rpm was impossible.

Inspection showed that the new Fidanza aluminum flywheel was missing the counter weight. Called Fidanza, and they said it should not have left the factory without the weight. They shipped the weight, but still waiting.

Previously the twin disk Ram clutch disk failed. The splines on the disk were not hardened and stripped, which destroyed the splines on the trans input shaft. Thanks ZFDoc for a new trans. But no thanks to Ram, and no refund.

It is a disgrace today of what you indicated. Hard to find quality as many after marked manufactures just want faster, cheaper, better. But seems like it's only cheaply made. I have gone thru similar situations, lots of lost time doing it 2 or 3 times.

It's a conspiracy against you. All the clutch manufactures have seen your name on the list.
