Does the Boxster clutch have a delay valve? My '98 M3 had one of these until I got rid of it, it's a restricted orifice in the clutch hydraulic line that slows the rate of clutch release, supposedly, to make clutch engagement smoother for city driving. I found it made it worse, and also led to bluing of my flywheel and early replacement.

If it's got one, get rid of it.
