I've got a question about gear shifting and letting out the clutch. One the street I drive pretty smooth (I think I may be over cautious) and release the clutch slow enough to minimize the driventrain lash/thunk/stress from quickly letting out the clutch.

In terms of performance driving, how much stress/thunk/lash can you put on the clutch/engine mounts etc...as you shift gears without long term damage? I don't ever drop launch the car from a stop but I'd like to know how far I can push the drivetrain with quick shifts from say 1st to 2nd, or quick downshifts from 4th, to 3rd or 2nd.
