Vibration at high speeds.

I have a 2016 GT M6 and when I'm doing over 100mph and in the high rpm i get vibration through the whole car. Currently I have stock driveshaft, i came to a conclusion that it could be the driveshaft and have been contemplating on upgrading to the DSS Aluminum one. Any thoughts?

I think some people have had some luck re-aligning the rear subframe. check your toe adjustments to see where they're set. That will give you an idea of the subframe alignment.

I am 90% convinced that I want to do the aluminum drive shaft on my car too, because it starts vibrating at about 65mph.

So depending on my toe, would i need to do a subframe realignment or change toe only?

if toe on both sides are adjusted in the same direction, it may indicate the subframe is off kilter.

these might help in that case

I am assuming that you've done all the easy stuff like making sure that your wheels are perfectly balanced and using a torque wrench on the spacers and lug nuts?

Yes I've done all that but at normal speeds everything is fine. When I get close to 100 and go faster it vibrates more and more.

Did your car do it before installing the spacers?

To be quite honest don't really remember. I would figure if it's spacers that it would do it any 50 or higher.

I had this issue, drive shaft eventually got replaced and vibration/noise went away.
There is a mega thread on vibration issue
