I recently purchased a 97 M3 with 50k miles. It has a slight vibration that you can feel in the clutch pedal when in gear and moving. No vibration when stopped and in nuetral. The vibration varies with engine speed and is more pronounced in first and second gear. It does not kick your foot off the pedal but if cruising and you rest your foot in the pedal enough to have the RB touch the pressure plate you can feel it. My mechanic seems to think that it is the flywheel. The clutch starts to grab halfway from the floor and doesn't slip. Does anybody know or have experienced anything like this. Thanks
