I know this topic has been talked to death, however I can't seem to fix it. I have replaced all the bushing, and gone through a couple shift nobs. currently I have a MOMO, I screw the thing down REAL tight (so much that there are grooves from the little screws on the shift lever). After a couple of days though, the thing starts vibrating again, what should I do?
also, are the M3 and M coupe shift levers compadible? if so, this would lower the heigth of the nob. My local dealer told me to try it out, but I thing he was just trying to sell me something.
