ok..so i went with the luk flywheel sincethey are the oem for audi....also installed rs4 clutch...two problems ive come across....when pressing the clutch pedal in ive noticed a slight vibratios at about 2/3 travel....depending on what rpm i shift at and how fast i push the pedal...doesnt happen all the time though...next is i took it into the high rpms ~5k..im getting a very high vibration....seems to be something out of balance....or something else?
