I've got a m6 and have 12,000+ miles on it and pushing the clutch in to change gears anywhere above 3000 rpms and it feels like there is some vibration in the clutch pedal and the shifter. It seems to be more so when u get to 5000+ I have not had a lot of time to take to the dealer yet but thought I would ask here cause I'm sure others have had that particular issue.
