Sup 5.5 gen peeps. I was wondering if anyone here has had their stock dual-mass flywheel resurfaced or not. Also, has anyone removed a stock flywheel and tried to turn the top part of it? I bought a used 6-speed flywheel and i can turn it fairly easily in one direction but it requires a bit more effort in the other. How can i tell if the damper within the flywheel is worn or not? Thanks in advance.
