[unplugged]

I recently bought a '16 BRZ Limited in early March. Today was one of the first days I really got to drive it more than 20 miles on open highway and not to the dealership.

At 500 miles, my alignment was out, they fixed the rear toe and everything now is in spec. Now at 628 miles, cruising around 70-75mph (yes within speed limits) my car will literally shift left or right and it doesn't matter which lance since I know the road crown can give a slight pull.

Around a slight right bend on the highway, the car literally went half way into another lane.

Had the alignment checked elsewhere, still in spec. I even looked under the car and found nothing out of the ordinary.

Now I know the car is light and it was a bit windy, but I never felt unsafe driving a new car. My C5 vette will handle these slight bends like nothing even in tornado storm weather. Granted it has a much lower COG, wider tires, and beefier suspension.

I'm wondering if this is normal for the BRZ, or if lowering it and having wider tires will help. Or is there something actually wrong with the vehicle.
