New Clutch and Flyweel Install and New Problem

[geoffbaltz]

I finally did the clutch and flywheel replacement. I went with the AASCO LWFW and the Spec Stage 1 Clutch with Spring Center.

I'm glad I did it since the old clutch was down to the rivots on the flywheel side. I also left the RMS alone as it was nice and clean in there and I'm a firm believer in the "if it works don't f%#* with it" theory.

The job itself was pretty easy as a clutch and flywheel job goes. I've done several on 944's and the 996 is a piece of cake.

I'm a bit concerned as I have a moderate shudder when starting in 1st gear and down shifting under load. I'm also getting a noticeable vibration/noise under 75% load in 1st and 2nd gear. I know it's not the noise from going to new flywheel as I was prepared for that (for all the people that ask if you can really hear the chatter when using a LWFW, yes, you can hear it). I think I may have bad motor mounts and now that the clutch hooks up stronger, the worn mounts are showing. I've been under the car and double checked everything and there is no evidence of missing anything on the clutch/flywheel job. I always torque everything to spec and mark every bolt on reassembly.

The mounts aren't leaking but I don't think that is always the case. I removed the driver's side mount and looked at it and it does have a date stamp of '99 on it so they are probably original. The car is a 2000 C2 w/74K miles on the clock.

Any thoughts or help?

Mine went the same time I was about to do a clutch job so I went to the solid RS mounts... great upgrade, highly recommend it.
