Anyone else experience their car acting unstable at speeds over 80 MPH. The car feels as if it is being buffeted by high winds.
I have replaced the wheels and tires, and no difference.

 

You may need to check your steering rack, rim circumference and tyre specifications.
if that checks out, realign the camber and weight distribution.

Let us know how it goes.

 

Same problem I’m having. It just started a couple months ago. Changed tires as well. Alignment is fine, they found that one of my front rim was bent which I had just had tires rotated to the front so that could be the reason I didn’t feel that because that rim was in the back. Maybe try rotating front rims and tires to the back???? Did you come to a resolution yet?
