Clutch shudder at takeoff

[san rensho]

I have the same problem. Its just a bit of chatter when launching at low rpm, 1200 of less. If I go above 2k rpm, the launch is smooth as silk. I changed the motor mount and it really didn't make a difference. Read somewhere its the dual mass flywheel.

My buddy, who has a 996, drove it said he didn't feel a thing, but he flogged the hell out of it. I try to launch as smoothly as possible, the clutch has 117k miles out of it so I want to milk it as long as I can.
