Formula Drivetrain Vibration First off, the car is a 96 formula m6.
I've noticed that over 75, in either 5th or 6th gear, there is a pretty bad vibration in the drive train, that continues to get worse as the speed goes up. We've tried a different set of wheels already with newer tires and that didn't solve it. Wondering if anyone else has had a similar problem or any advice? thanks.

I have the same problem on my 97 Formula, Anything over 70 becomes a little scary like you are driving on the edge of the highway on the part that lets you know you are off the road. Stock suspension.

I chased the same vibration in my 98 ss m6 for two years, 2 new drive shafts, wheels,tires, rebuilt my moser and sent my tranny to tick performance for a level 2 build and vib was still there long and short of it two weeks after tranny was in I tried to take out driveshaft and the tailshaft bushing came out with it, tick sent me a new tailshaft with a new bushing and all is great 130+mph. dont spend all the time and money I did and check that bushing.
