The clutch of my high milage williams seems a bit harsh. In low gears when i change up, i lift my foot slowly off the clutch pedal and the clutch engages in a pretty violent manner (ie it seems to jolt on). The best way to describe it is when your watching a race car from on board and the driver changes you see a violent jolt of the car as the clutch engages almost like the clutch is a switch (ie not progressive). Any idea why this is. I cant remember it on 0002. No other symptoms ans it does allow pretty quick changes.
