Here's an interesting thread from the ListServ in 2002.

I have a Fidanza on my ZR and have used one for close to 10 years including on my 84 Xfire w the ZF-6 Trans-plant I did. Although I do have the neutral idle rattle, it only becomes noticeable after the car has been run hard. Part of the reason I use the Camaro disk is because it is a "sprung hub". The hub helps absorbs some of the engine pulsing responsible for the ZF gear rattle. This in combination w the use of the heavier weight Castrol trans fluid does a good job dampening the rattle which occurs only at neutral idle. I have never heard my trans rattling under gas whether just cruising or hard acceleration.
Just switched to Amsoil Manual Synchromesh for the trans. In a short drive home from Pete's garage, I honestly didn't notice any difference in shifting. Jury is still out on whether trans rattles more or less than w Castrol.
