Dual Mass flywheel. It sucks. I konked my car out a couple of days ago. That hasn't happened in many years. It seems the previous owner wasn't that good with a manual. I drove a new one with no issues. I have read on here and everywhere I can. Lightened flywheel and Act clutch will go in mine when it is time. Z1 slave cylinder also. Already told the wife, the clutch is not right. So when the time comes and boxes start showing up I won't get any grief.
