My RS is currently on clutch #5!!!
All replaced under warranty. Every time the clutch is replaced, the shudder gets a little "better". Still, the new clutch shudders a few times when cold and, especially, when its cold and wet out.
Another "problem" I have with the latest clutch is that the pedal feel changes significantly in the course of a daily drive: as the car warms up, the pedal becomes easier to push, to the point where almost no effort is required to push it to the floor. Anyone else experience this?
