i have a spec stage 3 and have had it in for about 3000 miles and it was broke in for about the first 1000 just to be safe and yesterday there started to be more vibration in the clutch pedal than normal. and if i try to release the clutch with out any gas like i do in reverse the car jerks real hard. i know this clutch is grabby but it has never done this before. i have checked the fluid and it is fine. could the pilot bearing already be out it was new with the clutch. any info would be helpful. thanks
