Some days the clutch is perfect, absolutely smooth. Sometimes the engine will shake violently, even when the engine has just finished warming up. The clutch sometimes feels smooth even though is freezing outside and sometimes when it's like 5 C out I get the shudder. I don't launch the car, and am pretty easy on the clutch. When the clutch feels smooth, it feels numb and doesn't give me any feed back, 90 % of the time I get a slight vibration, which I am used to, but when I get a violent shudder, it just doesn't feel right. I got the shudder often when the car had about 2000 Km, now I have about 13000 KM and I rarely get it.
