Hello, so I have a base 2014 convertible mustang (manual) and I've noticed on the highway that the back end feels loose for a few moments every once in awhile.

I thought it was the wheels at first, and I pulled over and jacked it up to make sure they were properly on.

But I still kept feeling a 'looseness' every once in awhile. It was very unnerving.

Is what I'm feeling gust of wind ? I had an 06 gt with lowered eibach full suspension loadout before and never was affected by the wind like this.

Anyway, it's really unnerving. If its happening and I hit the gas, it goes away, that's why I think its the rear end.

Should I get my car looked at? If so what should I point them too...

If its because convertibles with their tops up are aerodynamically unstable, is there suspension stuff I can do to help?

 

does it have a trackbar back there? that's designed to keep the rear suspension in line...

 

I have a 2014 premium convertible and I don't notice anything you describe. I have modified, lowered and adjustable panhard, but I can't recall any issues prior. Wi,d buffeting in a vert can be a bit unnerving and you feel a pressure change due to flexing of the top. I got used to that pretty quick though.

 

I'm not sure. The mustang was a bone stock 14 convertible...
