I did a google search regarding the SPEC chatter an it appears people with LS-1'shave it also, some people don't mind it and others think it make there car sound like a 'POS'. Guess it may be something I could live with depending on when and how long it lasts. Is it just at take off or is it RPM related (meaning for example something that occurs from 1K-2K in first or all gears, just the first second or so after engagement, etc) Seems also that people with Fidanza's have had the chatter go away and some with SPEC flywheels it never went away entirely, hence I think I'll save the $75-$100 bucks and go with Fuadanza.
