could be the tires id check those first how bad of a vibration is it?

before you tear your hair out(which many do for this problem) have the tires match mounted and road force ballanced. it cures 90% of vibe cases, myself included.

+1 check the tires make sure they are squared away, also keep in mind it could be a driveshaft issue.... more than likely a balance issue though.

+1 for road force ballancing.

I had the same problem and my performance shop installed a pst carbon fiber driveshaft and balanced all of my tires. I now can take it too 100mph and its as smooth as a caddy!!!

I talked to Maximum Motorsports before I bought there solid diff mounts. They CLAIM that because the way the diff is mounted the pinion angle is different from the output shaft of the tranny angle it causes a high speed vibration.
Could be a sales pitch but I do know that the angles are supposed to match.
All I know is on the way home from the dealer I saw 150+ and was smoother than cars ive driven that are 3 times the money.

IRS might need re-alignment, I had similar problem and that's what it turned-out to be

just another suggestion
