Recently got my car back got a stage 3 southbend clutch and a steel light weight flywheel and an AWE DTS put in, so far pretty happy its grabs pretty nice but with a little bite as expected, but has anyone had alot of random grinding/chatter froming from the flywheel after replacing it with a lightweight single mass? It even sounds like its knocking at points almost like driving a diesel car. I know that there is some chatter expected at idling but not in gear at random rpms and gears. My shop told me that they only experienced chatter in first gear but after drving it for a whole day it didn't seem that way. TIA
