I noticed that in michigan today. My last car, a 2000 monte carlo SS sliced thru the wind but my first truck was a 98 1 ton dually I know what its like driving a brink down the road at 70..

 

Mine felt that way stock, but feels better lowered/leveled & sway bars..

 

My 2008 HHR feels a little unstable to me on the highway too especially at 75 mph. The wind makes the situation worse. The alignment is ok and the tires are balanced too. I'm getting ready to install a rear anti sway bar. I'm hoping that will help.

 

think: "Lower center of gravity"

 

I agree with Sleeper

being lowered and the addition of a rear sway bar will definitely lessen sway on a windy day at highway speed. but even with both I was getting knocked around pretty good this past weekend.

IMO in windy conditions you are going to feel it, regardless.

Just be ready to hit that blinker... so I looks like you meant to change lanes.

 

X2 when I leveled & installed sway bar it was much better. After about a year of driving it went on a road trip with my wife's HRR and said whats wrong with your car. When we got back did the same to hers, She says what a diff.!!!

 

Double check your tire pressures, if one is a little low, it will add sway.

 

Agree with the think lower...alot of the feel you have is the air getting under the vehicle and trying to lift the car/truck/suv/wagon
